line level outputs from home theatre processor to the AUX/HT input (see p.7). Volume control is now only possible (for this input) on the external processor.

Please note connecting standard line signals to these inputs in HT mode will cause very loud and damaging signals at speakers that cannot be controlled through the volume control. Please ensure correct AUX/HT switch position before using this input.

Selecting the AUX/HT input can also be achieved using the remote handset, using the corresponding button (see p. 8), but AUX/HT switching is not available on the remote.

TAPE

To use the TAPE input, connect external source to the TAPE input (see p.7). Select TAPE input using the source up/down buttons until TAPE is shown in the display.

Selecting the TAPE input can also be achieved using the corresponding button on the remote handset, (see p. 8).

RECORDING AND TAPE MONITOR

To record to tape, (or alternatively CD recorder, DAT, minidisk or computer soundcard analogue input) connect the tape out to the tape recorder line in. Press the input selector button on the front panel or remote control. This source will now be routed to the A1 TAPE OUT for recording by tape deck.

The recording can be directly monitored through the loudspeakers by pressing the TAPE MONITOR button. Press again to return back to the input being recorded.

On some 3 head tape decks there is an additional tape/source switch which should be in the tape position for this to work. If in doubt, please consult tape deck operating manual.

Note - adjustment of the volume control has no effect on the recording level.

Computer setup for input USB input

A good quality USB A to B cable is required to connect the unit to the computer.

Plug the B (square) end into the socket in the back of the A1.

Plug the A (rectangle) end into a free USB socket on the computer.

The computer should detect the new hardware and install a generic driver automatically (No setup or driver disk required).

CD, MP3, WAV files played on any software should now play through the A1. This device has been designed to work with PC Windows 98, ME, 2000, XP as well as Apple Macintosh OS X.

Please note:

This device is a high speed serial data processor, and by its nature, requires a very high volume of USB bandwidth. It will benefit greatly from being the only device connected on its USB ‘bus’. Sharing the same bus with other devices may cause unwanted artefacts such as dropouts or temporary loss of signal. This especially includes the use of the A1 on a USB hub/splitter alongside other USB components.
