Inputs and Outputs Notes
Nodal Voltage Amplifier): This circuit simplifies the
signal path of the amplifier, allowing the signal to travel through the amplifier at a low voltage. The result
is greater reliability, cleaner performance and
exceptional musicality with the speed, durability and power of MOSFETs.
MEHSA (Maximum Efficiency Heatsink
Application): MEHSA is a process that yields up to 5 times better
heat transfer than traditional FET mounting techniques using the exact same
components. A multiplayer insulated metal substrate operating with minimal
thermal resistance spreads heat both downward and outward to quickly dissipate
heat from each device across the heat sink.
Internal Crossover: The
built-in crossover, adjustable from 50 to 5000 Hz, can be set for high-pass or
low-pass operation, or it may be turned off for full-range output. The crossover
has a slope of 12 dB/octave.
Line Outputs: The amp includes
a pair of RCA line outputs for sending an unfiltered signal to another amplifier
or component without splitting the signal.
Front End Defeat: The Front End
Defeat is used to reroute the input signal around the signal processing
circuitry within the amplifier. While in the On position, all gain and crossover
functions are bypassed. This feature was designed for use with external
processors to provide the purest possible signal path through the amplifier.
Inputs and Outputs Notes
Set-screw Terminals: The power,
ground, and remote turn-on terminals are on the power plug connector, which
plugs into the power plug receptacle on the amp. The speaker terminals are on
the speaker plug connectors, which plug into the speaker plug receptacles. The
power and ground set-screw terminals will accept up to 2-gauge wire. The remote
turn-on and speaker set-screw terminals will accept up to 12-gauge wire.
Note: The power and
ground terminals each have an installed sleeve that allows you to use
8-gauge and smaller wire. The sleeves must be removed to use wire larger
The amplifier uses three 30A fuses, so
its total fuse rating is 90A. Since pre-packaged 4-gauge amplifier wiring kits
normally have 60A or 80A fuses, you will need to replace the fuse and fuse
holder in the kit with a 100A ANL fuse and ANL fuse holder.
