[. . . ] The output is on a balanced XLR connector. Group output and metering facilities are the same as on the Dual Group/EQ Module, though the meters can also be switched to display the stereo return signal. The stereo return section features a WIDTH control, as on the stereo input channels, enabling the operator to manipulate the stereo line source before routing to the mix. 2-band shelving EQ, at 60Hz and 12kHz, provides tonal balance control, and the stereo signal is routed via a balance control and a 60mm fader to any pair of groups, to the stereo mix bus, or in mono to the mix bus. Aux busses 1-4 can be addressed from the stereo return, via two rotary send controls, switchable to 1 and 2 or 3 and 4. Pre or post-fade status is set by internal jumpers. Full muting facilities are available on both the group output and stereo return, with PFL or solo-in-place on the return and AFL on the group output. MIDI Scene Set Module The MIDI Scene Set Module contains all the K3's facilities for internal mute configuration and external MIDI control. Up to 128 mute groups can be set up and selected from the front panel. In addition, the module can transmit a MIDI program change message on any channel when recalling a scene, to change an effects program, or select a new preset on an external device. MIDI control can also operate the other way around, using an external unit to select mute scenes or individual channel cuts on the K3. Any of the 128 mute groups can be instantly accessed by each of the 8 scene recall buttons. The DataFader on the MIDI module gives accurate control over almost any parameter on a range of effects and other units, such as reverb depth or pre-delay, using MIDI continuous controllers. Any single controller on any channel may be assigned in this way for each cue. A PREVIEW button is provided, which allows the operator to visually check any scene without forcing its operation. Additionally, an ALL function allows a common set of mutes to be copied to every scene before individual adjustments and programs are set. MIDI SysEx dumps in and out allow entire shows to be stored and recalled. Quad Matrix Module The single-width Quad Matrix Module provides facilities for distributing signals to a multiple speaker system which is, especially useful in theatre applications. Each matrix send can be fed from the eight subgroups, from the mono and stereo mix busses, and from a stereo external input at the rear of each matrix module. The external input can be set, by jumpers on the PCB, either to feed a mono sum signal to each matrix output or to feed the left input to odd numbered outputs and the right input to even numbered outputs. The slimline design of this module means that a full 12x4 matrix can be fitted into a console at the cost of only one input module. K3 Theatre consoles are fitted with one blank module which may be used for the first Quad Matrix Module. Outputs appear on individual balanced XLR connectors; external inputs utilise balanced jacks. Manual CUT and logic-controlled AFL buttons are illuminated for ease of use. Master Module The Master Module contains all controls for the stereo mix bus, mono and monitor outputs, plus master solo controls, oscillator, and 2-track returns. [. . . ] An 8 segment LED meter and a separate peak indicator shall be provided, plus a Preview LED to indicate the mute status of each channel for the previewed scene. There shall be a selectable pre or post EQ insert point using separate send and balanced return jacks. All connectors shall be integral with the main module. The Stereo Input Module shall have the following features; two switchable stereo line level sources on balanced jacks with a continuously variable gain range giving a sensitivity of -20dBu to +10dBu and a width control to vary the image from mono to a phase-enhanced stereo, a by-passable 3-band equaliser with shelving HF and LF operating at 12kHz and 60Hz and a mid control covering the range of 300-3kHz with a Q of 1, all controls having 15dB of cut and boost.
