Model Details


Four stereo input modules standard

More modules are optional.

Electronically balanced

XLR inputs and outputs.


Input and output transformers.

All insert In/Out points operate at +4dBu level

This is for optimum compatibility with pro equipment.

Continuously variable 50 dB Gain trim

In addition, switchable 30 dB pad let inputs handle any signal.

6-Step LED meters on each input

The LED meters on each input assist correct setup for optimum gain structure.

8 mono auxiliary mixing busses

In addition, two pair of stereo aux mixing busses that can be used as dual mono, for total of 12 auxes.

8 master mute groups

8 VCA groups

The groups have mute capability and full-length group faders.

8 primary mix busses ("groups")

The mix busses plus a stereo bus which can be "direct assigned" from inputs or from groups.

11 x 8 Mix Matrix

Extensive input-priority

It features "in-place" Cue system, plus Solo mode that mutes other channels.

Built-in fixed/variable frequency test oscillator and pink noise source.

The oscillator and pink noise source speed setup and overall system troubleshooting.

Large, dedicated stereo VU meters

Also, switchable VU meters for other busses (switching conveniently located next to operator).

Hundreds of LEDs

The LEDs indicate status, clip levels, and illuminate switches and meters-no lamps to maintain.

Extensive internal switches

In addition, jumpers to alter "default" console functions.

Lower noise than ever

It also features superb audiophile quality.

Multiple exhaust fans on rear panel

These fans keep circuitry cool for maximum longevity.

Dimmer-controlled "LittLites"

The "LittLites" are provided as standard equipment.

Redesigned chassis

This is for extraordinary strength and lighter weight.

PW4000 Power supply

The Power supply includes full-time AC line voltage digital readout and DC output monitor LEDs.
