Output Wiring Connections
All output wiring connections are made to the rear panel. Loosen the two Phillips-head screws on each side of the
Phoenix-style plug to connect speaker wiring (see Figure 6).
Balanced Line Output
The Balanced Line Output (BAL LINE OUT) is a line-level low-impedance balanced output that can connect to an
outboard amplier input. It carries the same signal that is sent to the inboard TPU amplier, but includes the gain
settings and controls of the TPU preamp. Any volume changes necessary for the Balanced Line Output should be
adjusted at the outboard amplier.
Speaker Connection
IMPORTANT: Before making any connections or wiring changes to the amplier, or any equipment connected to the
amplier, make sure that the amplier is NOT powered on.
The TPU600-G2 ampliers feature a single output connector for 8-ohm, 25V, and 70V speakers.
NOTICE
The minimum impedance of this 70V/8Ω high-impedance system should not be less than 8Ω (ohms). The combined total power of each
speaker tap must not exceed 80% of the rated amplier power. Failure to observe minimum speaker impedance will cause the amplier to
self-protect until the speaker conguration is corrected.
