Page 4: Test Procedure
SERVICE NOTE (120v Version only) Even though the Bass15 and 16 seem to have an on/off power switch, in fact the switch does not switch the main power off to the amp assembly, even in the OFF position. All AC and DC voltages within the amplifier are still active, so for safety concerns the AC power cord should be unplugged before any servicing begins. - Page 5 Powered Subwoofer BASS15/16 BASS 15 (120v US Version) BLOCK DIAGRAM...
