PRELIMINARY

Dolby Pro Logic Surround Decoder with Discrete 5.1ch Input

GENERAL DESCRIPTION

■■■■

NJW1107

The

is a Dolby Pro Logic Surr ound D ecoder with disc rete

5.1ch input. It inc ludes Dolby Pro Logic Surround dec oder, 4 m aster
volumes, 4 level trimmers and 6 switches.

The 6 switches cho ose internal Dol by Pro Logic S urround Decoder

or discrete 5.1ch inputs. The

NJW1107

is most suitable for AV

amplifier with discrete 5.1ch inp uts for Dolb y Digital.

In addition to Dolby Pro Logic Surround function, the

NJW1107

performs easily other surround function s uch as Hall, Live, Disco and
others, and echo and microphone mixing functions for Karaoke.
