Congratulations on selecting your new SPA25 Prisma Home Cinema Integrated Amplifier.
The SPA25 Prisma is a multi-channel integrated amplifier and processor designed for both cinephile and audiophile, composed of carefully considered and crafted features and functionality to provide the best home cinema experience for the greatest number of people.
This user guide describes the features and explains how to set up the SPA25 for the best sound quality and ease of operation in order to allow for the most enjoyable reproduction of sound from all your sources.
For additional support and assistance please contact your local authorized Primare dealer, or visit our website at www.primare.net.
Your SPA25 Prisma is supplied with the following components:
If any of these items are missing please contact your supplier. We recommend you retain the packaging in case you need to transport the unit at a later date.
Note that the SPA25 is supplied with a protective film on the display glass. Remove the film for a clearer display.
Connect the MAIN HDMI output from your SPA25 Prisma to your television or display HDMI input, noting that OSD (On-Screen-Display) is not available with the AUX HDMI output.
If your television includes an HDMI tuner output you can use the SPA25 to perform switching between the television tuner and your other video sources such as DVD or Blu-Ray. In this case connect the television tuner output to the HDMI input corresponding to your TV source. By default preset 1 uses the HDMI 1 input and Preset 2 uses the HDMI 2 input, but you can reassign these.
If your television does not provide a tuner output you will need to switch the television between its internal tuner and the external video input.
The SPA25 Prisma has nine channels of amplification to directly drive up to nine loudspeakers in variety of configurations of surround system configurations.
In addition, there are five analog line-level outputs – Front Left and Right, Centre, and two Subwoofer – to allow for the connection of external amplifiers, such as the A35.2 and A35.8, and up to two subwoofers.
The SPA25 provides up to 11 channels of audio processing to support:
For full details of how to connect up the alternative surround systems see Speaker configurations.
If your system includes one or more subwoofers:
You can connect five analog sources, one coax digital source, and two optical digital sources, as well as one USB-B digital input source to the inputs on the back panel.
Alternatively you can connect a 7.1 source to analog inputs A1 to A4 using four pairs of RCA cables.
You can also connect a PC or Mac to the USB-B input to use the SPA25 as an audio output device for your computer.
You can play music from a USB flash drive connected to the USB-A input, or stream music from a network-connected music server. For more information see Source options: Playing music from a drive or music server.

Enabling Speaker Mute allows for headphone listening using a headphone amplifier connected to the RCA outputs. Fixed can be selected when volume is controlled at the headphone amp, or Variable when you want to control volume from SPA25 Prisma.
Warning: Selecting Fixed could cause high volume levels on the analog RCA outputs.
The Video Settings menu allows you to configure the video outputs:
By default HDMI Pass-Thru is OFF, so HDMI OUT is off when the SPA25 is in standby.
If you want the TV to be connected even when the SPA25 is in standby, set HDMI Pass-Thru to either HDMI MAIN or HDMI AUX to connect HDMI IN 1 to HDMI AUX or MAIN output, while in standby.
Please note that HDMI pass-thru is only possible from HDMI IN 1 input.
Displays the HDMI Control (CEC) menu to allow you configure the HDMI control settings for this preset.
You can use CEC to automatically bring the TV connected to the SPA25 out of standby when you select a video source on the SPA25.
By default HDMI CEC is OFF. Setting it to ON allows you to set each of the subsequent options Ignore Power On, Ignore Power Off, and Ignore Switch Source to NO or YES to determine how the source behaves.
Choose ON (the default) or OFF to determine if the OSD has a transparent background.
Can be set to Always to leave the OSD permanently on the display, a time between 1s and 10 s to hide the OSD after a delay, or Never to never show the OSD.
Choose ON (the default) or OFF to choose whether help text is shown below each menu.
This section describes some typical speaker configurations that you can choose with the SPA25. For details of setting up each configuration see the next chapter Setting up speakers.

After connecting up your loudspeakers, to get the correct balance of sound from your surround system you need to configure the settings in the three submenus on the Speaker Settings menu.
The procedure for setting up the surround system is as follows:
Specifies which speakers you have in your surround system, and how they are connected to the SPA25.
Allows you to specify the crossover characteristics to be applied to each speaker.
Measure the distance from the listening position to the treble unit of each speaker and enter it in the Distance menu.
Using either an audio source, or the test tone, proceed through each of the speakers in your setup, and adjust the level in the Level menu to achieve a balanced sound.
The speaker presets make it easy to save your settings as a single, named configuration. You can define up to five presets, initially called Preset 1 to Preset 5, but you can give them names using the Alias option. You can access the speaker presets from each of the Speaker Setup, Crossover, Distance, and Level menus.
You only need to define one preset, but having more than one allows you to experiment with different configurations of your surround system. For example, you could have one preset optimised for solitary listening, and another which is ideal for watching movies with a crowd of friends.
The Speaker Setup menu allows you to define speaker presets, which configure the assignment of loudspeakers to the surround system.
Lets you select which loudspeaker preset you are configuring. To specify the preset:
or on the PRISMA remote to step to the preset you want to edit.Allows you to give the loudspeaker preset a memorable name. See Configuring the SPA25: Editing an alias for details of entering an alias.
Choose None (the default) if you are not using Dirac, or Slot 1 to Slot 4 to specify which Dirac configuration you want to use.
Allows you to reassign the Front Left and Right loudspeaker outputs to other loudspeakers in the surround system.
Choose Front (the default) to use the outputs for the main Front Left and Right loudspeakers, or Top Rear to use the outputs for Top Rear Left and Right speakers.
Choose ON (the default) if you have a loudspeaker connected to the Centre output, or OFF if there is no Centre loudspeaker.
Choose ON (the default) if you have loudspeakers connected to the Surround Left and Right outputs, or OFF if there are no Surround Left and Right loudspeakers in the system.
Choose ON (the default) if you have a subwoofer connected to the SUB 1 analogue output, or OFF if there is no subwoofer in the system.
Allows you to reassign the Surround Back Left and Right loudspeaker outputs to other loudspeakers in the surround system.
Choose OFF if you are not using these outputs, Surr. Back (the default) to use the outputs for the Surround Back Left and Right loudspeakers, or Top Rear to use the outputs for Top Rear Left and Right speakers.
Allows you to reassign the Height Left and Right loudspeaker outputs to other loudspeakers in the surround system.
Choose OFF if you are not using these outputs, Top Middle (the default) to use the outputs for the Height Left and Right loudspeakers, or Top Front to use the outputs for Top Front Left and Right speakers, or Bi-Amp Front.
Choose Overhead (the default) if the height speakers are ceiling mounted, pointing down into the room, or Upward Firing if they are pointing at the ceiling.
When the Height Type is set to Upward Firing the SPA25 Height outputs are set as Dolby Atmos enabled speakers. When the Height Type is set to Overhead the SPA25 Height outputs are set as normal speakers.
Allows you to specify the crossover characteristics.
Lets you select which crossover preset you are configuring. To specify the preset:
or on the PRISMA remote to step to the preset you want to edit.Allows you to give the speaker preset a memorable name. See Configuring the SPA25: Editing an alias for details of entering an alias.
Choose None (the default) if you are not using Dirac, or Slot 1 to Slot 4 to specify which Dirac configuration you want to use.
These menus allow you to specify the crossover frequency for each speaker or pair of speakers.
You can choose Full Range, or a crossover frequency from 40 Hz to 200 Hz in steps of 10 Hz. By default all speakers are Full Range, and the LFE is 200 Hz.
You can hold down or on the PRISMA remote to change the setting rapidly, and you will hear the effect in the current source you are listening to.
If you don’t have a subwoofer in your system, at least one pair of loudspeakers should be set to Full Range to handle the bass in the surround system.
If one or more speakers are defined as Full Range, the subwoofer receives the LFE signal (when available). You can also choose to send the subwoofer(s) a copy of the bass from the Full Range speakers by setting Double Bass to ON; see Setting up sources: Audio settings.
If no speakers are defined as Full Range, the subwoofer receives the LFE signal (when available), plus the bass from each channel.
Allows you to specify the distance of each loudspeaker from the listening position.
Lets you select which distance preset you are configuring. To specify the preset:
or on the PRISMA remote to step to the preset you want to edit.Allows you to give the speaker preset a memorable name. See Configuring the SPA25: Editing an alias for details of entering an alias.
Choose None (the default) if you are not using Dirac, or Slot 1 to Slot 4 to specify which Dirac configuration you want to use.
Choose Meter (the default) to measure distances in meters, Feet to measure distances in feet, or ms to measure according to the equivalent time delay.
These menus allow you to specify the distance of each speaker from the listening position.
The speakers go in order clockwise around the layout, starting from Front Left. In this menu you can specify the left and right speakers in each pair individually, because they may not be exactly the same distance from the listening position.
The range of options is as follows:
| Unit | Range |
| Meter | 0.00 m to 12.00 m in steps of 0.10 m |
| Feet | 0.00 ft to 39.36 ft in steps of about 0.32 ft |
You can hold down or on the PRISMA remote to change the setting rapidly, and you will hear the effect in the current source you are listening to.
Allows you to adjust the relative level of each loudspeaker.
Lets you select which level preset you are configuring. To specify the preset:
or on the PRISMA remote to step to the preset you want to edit.Allows you to give the speaker preset a memorable name. See Configuring the SPA25: Editing an alias for details of entering an alias.
Choose None (the default) if you are not using Dirac, or Slot 1 to Slot 4 to specify which Dirac configuration you want to use.
Plays a test tone instead of the current source.
These menus allow you to adjust the level of each loudspeaker, from -12.0 dB (quieter), to 0.0 dB (the default), to +12.0 dB (louder).
The speakers go in order clockwise around the layout, starting from Front Left. In this menu you can specify the left and right speakers in each pair individually, because they may not sound equally loud at the listening position.
You can hold down or on the PRISMA remote to change the setting rapidly, and you will hear the effect in the current source you are listening to, or the test tone if you have chosen that.
