Mono Inputs
24 mono channels with Mic [XLR] & Line [TRS] inputs. Line input overrides the XLR input. Individual +48V phantom power switches are provided. New padless two-stage preamp with smooth gain law. Line input goes to second stage for better matching and performance. Switched 100Hz high pass filter. Insert point. 4 band EQ. 4 aux mixes. Mute with LED. PFL button with LED [functions as peak indicator]. 100mm fader.

4 Band EQ
Shelving LF [60Hz], and HF [12kHz]. Fixed LM [250Hz], and swept HM [300Hz - 6kHz]. The fixed 250Hz control has been carefully selected to provide reduction of 'muddy' sounds and enhance 'warmth'

Dual Stereo Channels
Four stereo channels with two unbalanced stereo inputs on each. One is RCA one is TRS jack. Independent gain controls provide source mixing in the channel strip. The top inputs [RCA] can be switched direct to L&R instead of the channel strip providing extra returns. Two band shelving EQ. 4 aux mixes. Stereo balance, mute with LED, PFL with LED, and 100mm fader as mono channels.

4 Auxiliary Sends
From all channels: 2 pre-fade for foldback mixes - these have 100mm fader masters, mute switch with LED, AFL with LED, and TRS outputs [can be routed internally to output section]. 1 post-fade aux mix for FX - this feeds the internal FX and has a TRS jack output for external FX. 1 post-fade aux mix to TRS jack output is provided for external FX or special feeds.

Mix Outputs
Main stereo mix output has 100mm fader control & mute with LED. TRS jack outputs. Mono sum output with level control with switch for subwoofer mode to TRS jack. Record output [RCA] analogue + SPDIF switchable pre/post fader. Twin 12 segment LED bar meter shows program [or PFL /AFL]. Insert points on TRS jack for external processing. Output EQ and routing to internal amplifiers / external systems is provided.

Output EQ
4 band semi-parametric EQ is provided in the output section, this affects the TRS slave outputs, and the internal constant power amplifiers. This offers more control than graphic equalisers for precise management of speakers, especially foldback / monitors. Source selector allows output EQ section to be used on Left / right, L&R sum / foldback1, or foldback1 / foldback2.

Digital FX
16 program digital FX processor provides reverbs, delays, chorus and others, inc combined. This FX module takes its feed from the post-fade FX aux on the mono & stereo channels. The output of the FX module is controlled by a 100mm fader with mute & PFL and is routed to the stereo mix and FB1&2 with post fade level controls. At this point, 2 TRS inputs with level control provide a way of combining external FX with the internal unit. Internal FX unit can be switched off to use external only if preferred. A footswitch TRS jack is provided to mute the FX channel.

Master Section
Background music BGM mode - plays 2 track input into the main mix post fader, allows user to pull down fader (whilst patching, taking a break, or during walk-in) and leave music playing through the amplifiers / speakers. 2 track input [RCA] with level control to L&R - feeds headphone monitor selector [checking recording]. Twin, 3 colour 12 segment LED meter displays active monitor source. Large LED indicates PFL / AFL active - signal overrides L&R / 2TRK monitor source selection. Standby switch uses relays to disconnect the speakers. 2 track output [RCA] analogue + SPDIF allows direct to digital recording. Switchable pre / post master L&R fader. Mono sum out with level [TRS] - mode switch to provide sub feed with 100Hz low pass filter. Phones out [TRS] with level.

PSU
