Beautiful amplifier in excellent condition. A couple very minor small scuffs visible upon close inspection- please see the detailed pics. The plexiglass top is clean and unmarked.
Played the amp 4 channels driven @4 ohms and the sub channel @4ohms using 4 channel input with summed signal to the 5th channel, then 4 channels driven @4ohms and 5th channel input via the RCA Cinch Socket (located between the speaker outputs) @4 ohms. Pic shows in this configuration while listening to Neil Young Broken Arrow and America self titled CDs.
I tested function of the onboard crossovers and parametric EQ; All controls operate correctly and the amplifier sounds excellent.
Comes with a copy of the Instruction manual and will be properly packed.
