Select AUX as input source with the following set conditions:

Inject sine wave 2V at 1 KHz to L/R channels of AUX-IN socket.

Set DSC to JAZZ(Flat) mode and switch off DBB. Max off

Refence level for DSC's without DBB on=500mW.

Refence level for DSC'S with DBB on=1.7V at the speaker terminal .

Inject sine wave 2V to AUX-IN socket with frequencies indicated in Table 1.

Select AUX as input source.

Inject sine wave 2V at 1kHz to AUX-IN socket, one channel at a time (input level 500mV for /37,2V for /55 ).

Set DSC to JAZZ ( Flat ) mode and switch of DBB, OSM & INCREDIBLE SURROUND.

Adjust volume level to obtain 500mW across 4OHM load at L/R speaker output.

Inject sine wave 2V to AUX-IN socket withfrequency indicated in Table 3 (input level 500mV for /37,2V for /55 ).
