4700uF,50V electrolytic filter caps. Be sure
replacement part is at least the same
working voltage and capacitance rating.
Also the lead spacing is important.
Incorrect spacing may cause premature
failure due to internal cabinet pressure and
vibration.

Critical Components
All components identified with the IEC symbol
in the par ts list and the schematic diag ram
designate components in which saf ety can be
of special significance when replacing a
component identified with . Use only the
replacement parts designated in the par ts list or parts with
the same r ating of resistance , wattage or v oltage.

NOTE: CERTAIN DRAWINGS AND CONNECTIONS WERE DEPICTED INCORRECTLY IN SOME EARLY COPIES
OF THE PSW-D112 AND DPS-12 OWNER'S MANUALS .
THEY INCLUDE:
1.DRAWING OF RCA LINE LEVEL INPUT/OUTPUT JACKS ON PAGES 3, 4, &5;ALL CHANNELS -RIGHT SIDE
SHOULD BE LINE OUT, LEFT SIDE SHOULD BE LINE IN.
2.CONNECTION ON PAGE 4OFOWNER'S MANUAL -SINGLE CABLE DIRECT INPUT (FOR DOLBY DIGITAL OR
DTS SURROUND); SINGLE CABLE FROM YOUR RECEIVER/PROCESSOR SHOULD CONNECT TO:
Rev0 version -THE CENTER CHANNEL LINE IN JACK ON YOUR SUBWOOFER.
Rev1 version -EITHER LEFT OR RIGHT INPUT JACK ON YOUR SUBWOOFER.
THOSE DRAWINGS ARE CORRECT IN THIS DOCUMENT, SEE PAGES 8 & 9.
