Amps with an Attitude!
Voltage & Current circuit. This circuit protects the devices from
extending beyond their safe area of operation, but allows the
devices to provide high bursts of peak power with music, al-
lowing your amplifier to deliver more punch. When all is said
and done, this amplifier output topology offers a good combi-
nation of low quiescent amplifier heating and great distortion
performance at high powers for a reasonable complexity, reli-
ability, and value.
All output power is delivered through 4-circuit Speakon
®
con-
nectors. These connectors have been wired in such a way as
to allow you the most versatility. The Channel 1 and 2 connec-
tors are cross wired so you can cover all options, from dual
cable stereo (typical), to Bridge-Mono in one connector, to run-
ning a bi-amp speaker with one amplifier and one cable per
speaker cabinet!
The output relay, in conjunction with input signal mute circuit,
assures the amplifier will be well-behaved during turn on and
off. In the event of an amplifier output failure, a triac will fire
across the offending channel and act to protect your speak-
ers.
The turn on delay circuit functions to keep the output relay
open until all the voltages are up and stable, both in the ampli-
fier, and in all the components in the system ahead of the am-
plifier.
Heatsink temperature is monitored by a thermal probe at-
tached to the heatsink. As the temperature rises, the probe
sends a proportional current to the proportional speed fan cir-
cuit which starts the fan. Should the power transformer reach
its maximum safe temperature, an internal thermal switch
opens and the fan circuit turns on full speed to quickly cool
