Placing the unit

<Place the amplifier on a level, firm surface, avoiding direct sunlight and sources of heat or damp.

<Do not place the A38 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 A38 and P38 are 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 left of the front panel display is unobstructed, otherwise this will impair the use of the remote- control. If line-of-sight is impractical, a remote- control repeater can be used with the rear panel connector (see page 7).

<Do not place your record deck on top of this unit. Record decks are very sensitive to the noise generated by mains power supplies which will be heard as a background ‘hum’ if the record deck is too close.

Power

The amplifier is supplied with a moulded mains plug already fitted to the lead. Check that the plug supplied fits your supply – should you require a new mains lead, please contact your Arcam dealer.

If your mains supply voltage or mains plug is different, please contact your Arcam dealer immediately

Push the IEC plug end of the power cable into the socket on the back of the amplifier, making sure that it is pushed in firmly. Plug the other end of the cable into your mains socket and, if necessary, switch the socket on.

Stand-by power

For remote stand-by operation, the amplifier’s control power-supply is kept powered on all the time the unit is connected to the mains supply. The front-panel power- switch powers all other circuitry down and power consumption in this mode is less than 2W.

This means that even though the power-switch is off, it may be possible to hear a slight residual hum coming from the mains transformer inside the amplifier. This is perfectly normal. However, if the unit is to be left unused for an extended period, we recommend that you disconnect it from the mains supply.

Interconnect cables

We recommend the use of high-quality screened cables that are designed for the particular application. Other cables will have different impedance characteristics that will degrade the performance of your system (for example, do not use cabling intended for video use to carry audio signals). All cables should be kept as short as is practically possible.

It is good practice when connecting your equipment to make sure that the mains power-supply cabling is kept as far away as possible from your audio cables. Failure to do so may result in unwanted noise in the audio signals.
