Switching the A38 on

The power button switches the unit on and off; alternatively, the unit can be switched in and out of stand-by mode by pressing the 2 button on the remote control handset.

The power light (next to the ‘A38 Integrated Amplifier’ text) indicates the state of the amplifier:

1.A red light means that the amplifier is in stand-by mode;

2.When you switch your amplifier on, the power light glows amber for a few seconds; during this time the outputs are muted;

3.The light changes to green when the amplifier is ready for use.

The power light may flash if a fault has occurred – the fault type is shown on the display. See page 17, ‘Troubleshooting’, for help in resolving fault situations.

If the fault cannot be cleared, unplug your amplifier and contact your Arcam dealer.

Changing the volume

Use the control knob to change the volume. Turn the knob clockwise to increase the volume, anti-clockwise to reduce it.

The output of the A38 can be muted by pressing mute. Press mute for a second time (or change the volume) to cancel the mute.

SP1 and SP2

These buttons allow you to switch the main speakers (connected to the lower set of speaker terminals) and secondary speakers (connected to the upper set of speaker terminals) on and off.

The light above each button glows if the corresponding speakers are currently selected. If you have connected the A38 to the speakers using the single-wired configuration described on page 9, then the SP1 light should be illuminated; if you have used the bi-wiring configuration described on page 9, both SP1 and SP2 must be switched on. Note that when both lights are out then the amplifier will appear not to work, as all speakers are switched off.

When listening to ‘loud’ inputs, such as CDs, the amplifier may reach its full power before the display reads Maximum, in contrast, lower-level inputs, such as tuners, will sound quieter for the same volume level shown. To compensate for this, the input levels of each source may be adjusted. This can be done using the A38 setup menu (see page 11).

Selecting an audio source

A source-selection button is used to select the source that is connected to the input corresponding to the button. A light above the relevant button indicates which input is selected and this information is also shown on the display.

Listening using headphones

The headphones socket (Phones) accepts headphones with an impedance rating between 8Ω and 2kΩ, fitted with a 6.5mm stereo jack plug.

The pre-amp. outputs and speakers are muted when headphones are plugged in. The headphones socket is always active, unless the volume has been muted.

Balance

In addition to the A38 setup menu (see page 11), you can also control left-right stereo balance directly from the Balance button on the front-panel.

Display

The Display front panel button changes the display brightness. There are three brightness levels: ‘on’, ‘dimmed’ and ‘off’. If the A38 is switched off while the display is set to ‘off’, the display is set to ‘dimmed’ when the A38 is switched on again.

Recording an audio source

The A38 allows listening to and recording from the same source, or listening to one source whilst recording another. The signal to be recorded is sent to both the AV and PVR output sockets.

Selecting the source for recording

The recording outputs can be configured in two ways:

1.To allow recording of the source being listened to;

2.To allow recording of a particular (specified) source, regardless of what is being listened to.

To record the source being listened to, press the RECORD button repeatedly until the display shows ‘Record source’. After a few seconds, the display reverts to showing the volume level, and you are ready to record. In this configuration, selecting a different input changes the source that is routed to the recording outputs.

To record one source whilst listening to another, press RECORD until the display shows ‘Record’ followed by the name of an input (e.g., Aux, CD, Tuner, etc.). Now press the source-selector button on the front-panel for the source you wish to record. Your selection is shown on the display for a few seconds, after which the display reverts to showing the volume level. You are now ready to record.

Pressing a different source-selection button changes the source that you are listening to, but does not alter the source that is routed to the recording outputs.
