All input, output and power connections should be made with the mains power switched OFF.

INPUT CONNECTIONS

The A308 integrated amplifier has one pair of phono inputs, which can be used either for moving magnet (MM) or the lower out- put moving coil (MC) pickups.

The phono input sensitivity requirement can be changed from MM to MC by press- ing the MM/MC push-button switch locat- ed on the rear panel.

Important - Do not operate the MM/MC switch with the volume control turned up.

Some turntable/pickup arm combinations are fitted with an extra wire for chassis earthing. This should be connected to the earth terminal on the back panel.

The A308 also has four “line level” inputs controlled by the internal volume setting. They all have the same input sensitivity, and are therefore suitable for use with any source component having an output of at least 300mV. The four sockets on the rear panel are marked CD, TUNER, AUXIL- IARY 1, and TAPE, corresponding with function selector buttons on the front panel.

The AUXILIARY 2 (HOME THEATRE

DIRECT) sockets are intended for home the- atre use. When selected, they are routed inside the A308 directly to the power amplifier circuit, which is not controlled by the volume adjustment.

Do not therefore connect these sockets to a source without its own volume control.

CONNECTIONS

Using good quality co-axial audio leads, connect the left and right outputs from your CD player to the CD sockets, your tuner to the TUNER sockets and any other source to the AUXILIARY 1 RCA input sockets.

Connect the A308’s TAPE input sockets to the line output of your tape recorder, and A308’s TAPE RECORD output sockets to the line input sockets of the tape deck.

OUTPUT CONNECTIONS

Connect your loudspeakers to either of the two pairs of terminals on the back panel marked as LEFT and RIGHT SPEAKER outputs. Note: the combined load imped- ance must not be less than 4 ohms.

PRE-AMPLIFIER OUTPUT

The A308 amplifier has its pre-amplifier output available from RCA sockets on the back panel marked PRE-OUT, and is con- trolled by the volume adjustment.

This is to allow “bi-amplification” using suitable external amplifiers and crossover networks to power the speaker drive com- ponents separately, giving noticeable improvement in clarity, imaging and bass weight.

In this arrangement, typically the A308’s speaker outputs are used to drive the speak- er’s “tweeter” (high audio frequencies), and an external stereo amplifier drives the “woofer” (low frequencies).

The A308’s PRE OUT RCA sockets would therefore be connected to the input of the external “woofer” amplifier in this example.

If you are in doubt about bi-amplification, please contact your dealer for advice.
