Introduction
K3 Standard Console The K3 Standard Console is designed to offer value for money, and versatility that
allows the desk to perform to a high standard in a wide range of applications, from
touring rigs and medium sized band PA to fixed installations in medium sized
theatres and concert halls, conference halls and so on.
The K3 is available in five different frame sizes 16, 24, 32, 40 and 48 channels. The
choice of frames and modules means that the desk can be configured to match your
needs and budget. Good ergonomics, plus an advanced mute system and MIDI
control module, make the K3 easy for any operator to get to grips with, and exploit
its range of facilities to the full.
K3 Theatre Console The K3 Theatre is designed to offer the ultimate in control and quality from a
mid-range PA console. Based on the K3 Standard, the K3 Theatre is a modular 8-bus
console with a special mono input module featuring enhanced EQ plus refinements
such as individual routing to groups. Along with all the other K3 options, such as
choice of group modules, stereo input modules, and a slimline matrix module, the
K3 Theatre makes it easier than you ever thought possible to mix a large number of
varied mono and stereo sources in a range of sound reinforcement situations- band
FOH or FOH and monitor mixing, installed or theatre sound with a multi-speaker
rig -all with the benefits of MIDI mute control, and the K3’s exceptional ease of
use.
The K3 Theatre is available in 16, 24, 32, 40 and 48-channel frame sizes, with an
optional VU meter overbridge.
Module Options
Each frame includes:
•Either Standard or Theatre Inputs.
•4 X Dual group/EQ or group/FX output modules.
•1 X MIDI scene set module.
•1 X Master module.
•1 X Blank module
•1 X CPS275 Power supply (48ch Theatre version needs two).
Optional fittings include:
•Quad matrix modules.
•Stereo input modules.
•VU Overbridge (Factory fitted).
•Additional CPS275 for backup supply, links to main supply with short cable.
•Dual Group/EQ or FX modules.
•Mic I/P transformer options.
1.2 Introduction

Metering A VU output overbridge is available for all K3 frames, except for 16ch. The VU
meters provide metering of the Group and Mix signals and monitor the Mono bus
output.
Additionally, the 8 VUs which normally monitor the group signals can be switched
from the front panel to read the Matrix outputs or the Aux outputs.
Power Supplies The K3 requires the CPS275 power supply unit. The CPS275 has built-in diodes in
the output. This allows a second power supply to be connected in "parallel" with
the main supply such that if any rail on either supply fails, the other CPS275 will
immediately supply the power.
Note: Although the supplies are "in parallel", they will not necessarily
share the current because the rail voltages will not be exactly equal.
When you order a spare CPS275, this comes with a short link cable which connects
from the spare supply’s "link" output into the "link" connector on the main supply.
