7/7 AMP 200.4

3 CHANNEL “2 SAT + SUB” MODE:

You can use the amplifier to drive 2 satellite speakers + a mono subwoofer (no external crossover needed).

The subwoofer will be driven in bridge mode for more power.

IN.C → OUT.C = Satellite L 100Wrms @ 8Ω ~ 200Wrms @ 4ohm

IN.D → OUT.D = Satellite R 100Wrms @ 8Ω ~ 200Wrms @ 4ohm

IN.C + IN.D → OUT.A = Subwoofer = 1x 400W @ 8 ohm. Attention: loads below 8Ω are NOT allowed

IMPORTANT: the wiring of the CH.A subwoofer connector in bridge mode is DIFFERENT ! Check the

information about the speaker output wiring below.

• Connect the audio signals to the inputs IN.C (15) and IN.D (16)

• Set the operation mode switch for channel C and D (24) to “2SAT+SUB”

• If you use small satellite speakers, switch the High Pass Filter (25) ON. If you use bigger speakers

(f.ex.15”) and you want to run the satellite speakers in full range mode, you can leave the HPFilter OFF.

• Set the operation mode switch for the subwoofer channels CH.A&CH.B (22) to “BRIDGE”

• Switch the Low Pass Filter (23) ON

• Connect the satellite speakers to the outputs SAT.L & SAT.R (19&20)
