I15 – integrated amplifier
I15 is an all analog integrated amplifier, featuring 60 watts of power per channel, and the option of adding the MM15 moving magnet phono stage at any time.
With the three-quarter-sized compact cabinet of I15, even greater possibilities open up for providing the highest quality music performance in even the smallest of living spaces.
I15 utilises the same Hypex all analog class D power module as used in the award winning I15 Prisma. But, without the need to provide power to the digital to analog conversion stage and network player found in the I15 Prisma, the power supply has been configured to allow I15 to perform with even greater drive and detail.
The look and feel of Scandinavia
We believe that every aspect of our products – the way they look, the satisfying feel of the controls – contributes to the overall experience of living with Primare. As a result, Primare products exude the hallmarks of Scandinavian design – simple, elegant designs, with approachable and easy to understand functionality.
An example of this is the compact, essentially three-quarter sized, of the 15 series, cabinets creating the sense of perfect proportions being just right for allowing placement within any living environment – or as we say lagom, not too much not too little, everything in balance, proportion, and harmony.
With the 15 Series, we offer a carefully considered array of models in order to allow for the best selection to fit any of your system needs. For example, the ultimate 15 Series system might be the DD15 CD transport, SC15 Prisma preamplifier and network player, I15 analog integrated amplifier, and R15 MM/MC phono preamplifier, allowing for the best performance, analog or digital, with the greatest number of connection options. However, there may be no need for additional digital inputs, MC phono preamplification may not be requirement, or simply to address budget or size considerations, a system composed of CD15 Prisma CD and network player with an I15 MM integrated amplifier with MM15 MM phono module installed could be assembled. This compact and reasonably priced system provides multiple analog source playback, including vinyl disc, as well as digital disc, stored or streamed media playback, with remarkable power, control, and connection flexibility.

I15 – integrated amplifier
I15 Prisma is an integrated amplifier and network player – capable of providing exemplary performance whether the source is analog or digital, stored or streamed, wired or wireless.
Continuing a Primare tradition of delivering astonishing performance from compact and elegant devices for easy installation into virtually any living environment, I15 Prisma’s three-quarter sized cabinet offers even greater possibilities for providing the highest quality music performance and access to any and every room in the house.
I15 Prisma provides 60 watts of output power per channel, digital to analog conversion with up to PCM 384kHz and DSD 128 capabilities, as well as complete digital media access and system management by way of the Prisma connectivity and control technology.
Prisma provides multi-room/multi-zone connectivity and control for playback of stored and streamed media, wired or wireless, all managed from any mobile device through a dedicated system control app. In addition to Bluetooth, AirPlay, and Spotify Connect, Prisma features Chromecast built-in, a unique streaming portal allowing effortless direct connection to hundreds of streaming applications for the best possible performance and user experience.
- Design Philosophy
- Amplifier Technology
- Digital to Analog Conversion Technology
- Prisma Connectivity and Control Technology
All of Primare designs are a result of our Practical Design Approach, resulting in a focus on two fundamental design elements:
Thoroughly implemented power supply designs – so that all elements of any design to operate effortlessly at their fullest effectiveness. Every product and sub-circuit demands unique power supply solutions – a more conventional linear supply or advanced switch mode main supply may work best dependent upon the application, and carefully crafted individual discrete power supplies are strategically inserted into the circuit to deliver power exactly where and how much is needed.
Artfully crafted ultra-short signal paths – so that each individual component and sub circuit operates sympathetically to achieve a cohesive whole. Elegant and simple electrical designs are used in even the most complex product, utilizing ultra-short signal paths with all gain in one device whenever possible. Ultimately, this results in fewer, higher quality parts for a reduction in associated distortions and an increase in overall electrical efficiency.
To that end, basic technologies have been selected to realize those benefits:
- 2 and 4-layer double-sided circuit board construction allows for the most direct and efficient layout of circuit components not only for the shortest signal path, but also to more easily achieve a sympathetic layout of circuit and sub-circuit components for best performance.
- Surface mount components are used whenever possible as this allows for direct connection of the circuit device or component to the circuit board trace with the solder being used solely to mechanically hold the part in place. The elimination of the small metal lead or wire at each connection point in a more conventional large scale circuit device or component cumulatively shortens the signal path. Additionally, conventional large scale components demand through hole or “eyelet” construction, limiting direct contact of the component’s lead to the circuit board trace and resulting in the solder providing electrical connection as well as mechanical connection for the device. Neither solder nor the metal used in the leads of most large scale devices provide the best signal transmission, therefore limiting potential performance of even the best designed circuits.
- Class D amplifier technology has many inherent advantages, one of which is the ability to locate the heat sink directly on the circuit board within the amplification module, considerably reducing circuit path length and allowing for the power output devices to be directly connected to the speaker output connection posts.
Carefully crafted input circuitry utilizes relays for input switching providing better isolation and sound than found in more conventional CMOS (Complementary metal–oxide–semiconductor) switches, and improved 2 x 4 channel balanced mode volume control IC selected for optimal channel balance and low listening level performance.
The latest generation OLED display technology used in the I35 was originally developed for the automobile industry to ensure long life in even the most hostile environments, and improved readability due to greater consistency of color value and brightness level.
Auto sense input circuitry automatically selects any input source as it is activated.
C25 IR remote control with completely new, proprietary control codes for faster response and reduced interference.
RS-232 connection, in addition to being used for component quality control testing of each and every product, allows for the use of whole home system control technologies such as Control 4.
12V triggers for coordinated system turn on and turn off.
Either from the front panel, C25 IR remote control or Prisma app, the I15 Prisma can be configured to best suit system needs, including:
Status – enable or disable the input to make it visible or not, so only those you use are visible for easier input selection
Alias – edit the alias, or rename, each input to give it a specific name, for easier identification
Auto-sense – enable auto-sense to determine which inputs will be automatically selected when a signal is detected
Volume – choose between variable or fixed volume, allowing any input to pass through the preamp stage to connect directly to the amplifier for use of within a home theater system configuration.
Or fixed gain setting allows for any input to be use in a theater or surround sound pass through configuration
Input Gain – adjusting the input gain so that all inputs to be at the same relative volume level, and as result the ability to raise or lower overall gain for preferred output volume setting
Balance – to adjust the output balance between the left and right speaker
Startup volume – sets the volume level at a predetermined level upon turn on from standby or at the level when last switched off.
Maximum volume – sets the maximum volume
Mute volume – sets the output level when muted, from 0 to any preferred setting
Digital output – to select between 48kHz and 96kHz settings for the digital output from analog inputs, as some devices in your system might not be compatible with the default 96kHz output.
Show inputs – choose between showing all enabled inputs or only those with signal
Front panel – to lock the front panel to disable all front panel controls
Auto dim – select the amount of time at which the front panel display will dim
LED brightness – set the level of display brightness for three specified dim levels
Standby mode – select
“normal” standby, which allows any activated input device set to “wake up” enable to wake up the Prisma integrated amp or preamplifier from standby
or “Eco” in order for the device to consume less than 0.5W in standby mode, disabling auto wake-up
Auto-standby – sets the amount of time without user interface action or signal from last selected source before the device automatically goes into standby
Wake up – enables auto-sense to wake up the device from standby upon detecting an input signal source
Factory reset – allows for the device to be returned to factory default settings
The I15 Prisma employs a specially made Hypex UCD102 amplifier module, fed by our custom heavy duty switch mode power supply and carefully crafted analog input stage, provides a dynamic and detailed sound. The large scale mass production of this module allows us to provide the balanced and coherent sound for which Primare has become known at a more reasonable price than can be achieved with our limited production UFPD 2 amplifier module technology.
Power Supply Section
Given the speed with which the Hypex amplifier module is able to deliver power to the speaker a switch mode power supply was the only choice in that it allows for rapidly varying demand, providing much more stable voltage, with ancillary capacitive storage to meet peak transient burst requirements.
Digital to Analog Conversion (DAC) Technology
In order to allow for playback of virtually any digital source with absolute accuracy and musicality a high performance 32-bit stereo AKM DAC AK4490EQ chipset was selected for the I15 Prisma, incorporating AKM’s VELVET SOUNDTM technology, and capable of achieving -112dB THD+N with 120dB (stereo) S/N, while supporting up to 768kHz PCM and 256/11.2MHz DSD.
The AK4490EQ integrates a newly developed switched capacitor filter “OSR Doubler” that greatly reduces sound degradation from noise shaping, achieving a flat noise floor up to 200kHz. An innovative design technique utilizing a symmetrical layout for the left and right channels prevents signal quality deterioration, and a 32-bit digital operation block provides full 32-bit processing.
Prisma Connectivity and Control Technology
Prisma provides multi-room/multi-zone connectivity and control for playback of stored and streamed media, wired or wireless, all managed from any mobile device through a dedicated system control app. In addition to Bluetooth®, AirPlay, and Spotify Connect, Prisma features Chromecast built-in, a unique streaming portal allowing effortless direct connection to hundreds of streaming applications for the best possible performance and user experience.
Prisma App, in addition to the configuration settings control listed above, provides:
Switching of all inputs, analog and digital, stored or streamed
Playback functions: Play, stop, track forward and back, shuffle play, repeat single or all tracks, volume mute, volume adjustment either by tapping the -/+ icons or sliding your finger across the volume bar
Multi-room multi-zone control between other Prisma enabled devices
Search by artist, album, track, and title from stored media
Complete track information, including file format, bit and sample rate
Playlist and Queue creation from stored media
Digital – USB-A
Sample rates up to PCM 24/192kHz and DSD 128/5.6mHz
File formats: WAV, LPCM, AIFF, FLAC, ALAC, MP3, MP4 (AAC), WMA, OGG, DSD
Wired/LAN – two Ethernet connection ports allow Prisma to act as network switch for flexible wired network system connection options
Wireless/WLAN – dual band wireless technology (WLAN IEEE 802.11 a/b/g/n and 802.11ac compliant)
Bluetooth – connects Apple, Android, and Windows devices directly for playback of either streamed or stored content from the associated device with lossy compression. Given the wide availability of this technology and lower resolution capabilities, Bluetooth is an easy way to stream content for informal listening.
AirPlay – connects Apple devices over the WiFi network for playback of either streamed or stored content from the associated device with lossless compression. As a result, AirPlay has the capability of playing over greater distances than Bluetooth, and as the Apple Lossless Audio Codec is used to allow streaming quality up to CD quality (44.1kHz), is appropriate for more critical listening.
Spotify Connect – connects any device with the Spotify application over the WiFi network directly to that service, and allows for playback at the highest level offered by the required Premium service (up to 320 kbps).
Chromecast built-in – offering the greatest level of connectivity and control options:
The Chromecast built-in associated Google Home application connects the Prisma device to your WiFi network for casting hundreds of enabled music streaming services.
Because it provides a direct connection between the I35 Prisma and the preferred music service through the network, playback quality is limited only by the quality of resolution provided by that service, meaning the possibility of higher resolution playback from services like TIDAL HiFi and Qobuz (up to 24-bit/96kHz).
More than one device can be connected at a time, content can be cast to any Chromecast built-in device on the network, and control of all functions can be accomplished from anywhere within the network.
Automatic Prisma firmware updating through Google Home application.
Voice control though the Google Home speaker and Google Assistant is anticipated as that system becomes readily available
