5/7 AMP 200.4
• BRIDGE: used when you need more power. Only the mono signal on input INC (15) is used to
drive the combined “bridged” output OUT.C (19). Only speakers with impedance >8ohm are
allowed.
IMPORTANT: the wiring of the CHA speaker connector in bridge mode is DIFFERENT ! Check
the information about the speaker outputs below
25. HIGH PASS filter switch: When ON, only frequencies above 120 Hz will be sent to the output(s) OUT.C
& OUT.D. This is very useful when you want to connect small satellite speakers and don’t want to use
them in Full Range mode.
HOW TO USE
Both amplifiers can be configured separately in 4ways to obtain several configurations.
STEREO OPERATION ON ALL 4 CHANNELS:
Used to drive 2 separate stereo outputs or 4 mono outputs (4 channels):
IN.A → OUT.A = 100Wrms @ 8Ω ~ 200Wrms @ 4ohm
IN.B → OUT.B = 100Wrms @ 8Ω ~ 200Wrms @ 4ohm
IN.C → OUT.C = 100Wrms @ 8Ω ~ 200Wrms @ 4ohm
IN.D → OUT.D = 100Wrms @ 8Ω ~ 200Wrms @ 4ohm
• Connect the stereo audio signals to the inputs IN.A (13) IN.B (14) IN.C (15) and IN.D (16)
• Set the operation mode switches (22&24) to “stereo”
• Connect the speakers to the outputs.
• Set input gain knobs (7/8/9/10) to zero
• Make sure there’s a music signal at the input
• Turn the amplifier on (1)
• Adjust the gain knobs (7/8/9/10) to the desired level
4 CHANNEL MONO MODE:
Use only 2 inputs to drive the 4 outputs :
4x 100Wrms @ 8Ω ~ 4x 200Wrms @ 4ohm.
IN.A → OUT.A + OUT.B
IN.C → OUT.C + OUT.D
