Placing The Unit
- Place the amplifier on a level, firm surface, avoiding direct sunlight and sources of heat or damp.
- Do not place the A5/A15/A25 on top of a power amplifier or other source of heat.
- Do not place the amplifier in an enclosed space such as a bookcase or closed cabinet unless there is good provision for ventilation. The A5/A15/A25 is designed to run warm during normal operation.
- Do not place any other component or item on top of the amplifier as this may obstruct airflow around the heat-sink, causing the amplifier to run hot (the unit placed on top of the amplifier would become hot too).
- Make sure the remote-control receiver to the right of the front panel display is unobstructed, otherwise this will impair the use of the remote-control.
The A5/A15/A25 is designed to run warm in normal use, however extended use at high volume levels can result in the amplifier casework becoming hot to the touch.
This product offers the user the option to deactivate power management functions. Note that doing this will increase energy consumption of the product.

Input Selection
Using the left← and right→ cursor buttons on the remote control.
Connecting Loudspeakers
Step 1, ensure power is disconnected from the amplifier.
Step 2, using speaker cables, connect the red positive terminal of the right
speaker output (R+) on the amplifier to the positive (+) terminal of your
right speaker.
Step 3, connect the black negative terminal of the right speaker output (R-)
on the amplifier to the negative (-) terminal of your speaker.
Step 4, repeat the process for the left speaker, using the terminals labelled
L+ and L- and on the amplifier.
Top Tips
- Check all connections thoroughly. Ensure that exposed wires or cables are not touching each other or the amplifier’s chassis (which can cause a short circuit), and that you have connected the positive (+) and negative (–) terminals correctly. Be sure to check the wiring for both the amplifier and the speakers.
- After making connections: switch the amplifier on with no input and reduce the volume to minimum. Select a source signal, and then slowly increase the volume to a suitable listening level to avoid loud sounds or product damage in the event of incorrect connection.
- If you are unsure as to how your system should be connected, please contact your ARCAM dealer who will be happy to help you.
Bluetooth Operation
Connecting your phone or tablet:
- To pair your Bluetooth source device, open the Bluetooth settings on your source device and scan for A5/A15/A25 ###### from the list. Each product has a unique ID.
- By default, the amplifier does not need to be on the BT input for Bluetooth pairing of a source device.
- The Amplifier can recall 5 device pairings. If 5 are in memory already, the oldest will be replaced.
- Because portable devices often have a volume slider, there is a maximum volume setting in the amplifier to prevent excessive volume output being selected accidentally. The default is 40.

menu, see page 10.
Selecting Inputs
Audio inputs can be selected using either:
- The INPUT selector on the front panel. Rotate the dial to the input and press to select.
- Using the left← and right→ curcor buttons on the remote control. In each case, the source name corresponds to the labelled input sockets.
The inputs are:
- Phono (analog – turntable with moving magnet cartridge)
- Analogue 1, Analogue 2 and Analogue 3
- Digital 1, Digital 2, Digital 3 and USB-C (USB-C on A25 only)
Note: The digital inputs only support stereo (PCM) audio. Multichannel
audio or encoded audio of any type is not supported.
Phono Input
The Phono Input includes a pre-amplifier to work with a MM (moving magnet)
cartridge on a turntable for playing vinyl.
NEVER connect anything other than a turntable through this input. This
can result in serious damage to both your amplifier and speakers and will not
be covered under warranty.

Troubleshooting
Problem | Check the following |
---|---|
No sound from Bluetooth headphones | Check the headphones have not connected to |
another device like a phone or tablet before the amplifier could connect to
them.
If your headphones have a power saving auto mute function when removed from
the head (head detection), they may need to be unmuted to restore sound when
refitted.
No sound| Is the amplifier correctly plugged in and switched on?
Is the audio source correctly connected, with the correct input selected? Is
the amplifier muted?
Is the amplifier in protection mode (as described below)?
Sound cuts-out unexpectedly| The amplifier may enter a protection mode. The
front panel display indicates the fault type:
· FAULT DC OFFSET: The amplifier detected an overload. Power off and reduce
the volume after turning back on.
· FAULT SHORT (CIRCUIT): The amplifier detected a speaker short circuit.
Inspect all the speaker cables to make sure none of them are shorted together.
This fault is more common when exposed wires are being used to make speaker
connections.
· FAULT OVER TEMP: The internal temperature of the unit reached an unsafe
level. Allow the amplifier to cool.
In protection mode, the amplifier will turn itself off and power to the
speakers will be removed. To continue using the amplifier, the fault must be
treated, and the amplifier must be turned OFF then back ON from the power
switch on the rear panel.
The amplifier does not respond to the remote control| Are there fresh
batteries in the remote control?
Are you pointing the remote control towards the amplifier window without
obstruction?
The front panel display is blank| Is the amplifier correctly plugged in and
switched on? Is the amplifier in standby?
Is the display dimmed to “Off”?
Press the button on the remote control.
Hum on the analogue input| Ensure all cables are making a good connection.
Try disconnecting the input cable and plug it fully in again (turn the power
off before doing this).
If the Hum stops when the source is disconnected, the problem is most likely
to be in the cable or the source device to which it is connected.
