with liquids, such as vases, on the apparatus. No naked flame sources, such as lighted candles, should be placed on the apparatus. Ventilation should not be impeded by covering the ventilation openings with items such as newspapers, table cloths, curtains etc. THIS APPARATUS MUST BE EARTHED. Under no circumstances should the safety earth be disconnected from the mains lead. The mains supply disconnect device is the mains plug. It must remain accessible so as to be readily operable when the app

WIRING UP Mic Input The MIC input accepts XLR-type connectors and is designed to suit a wide range of BALANCED or UNBALANCED low-level signals, whether from deli- cate vocals requiring the best low-noise performance, or drum kits needing maximum headroom. Professional dynamic, condenser or ribbon mics are best because these will be LOW IMPEDANCE. While you can use low-cost HIGH IMPEDANCE mics, you do not get the same degree of immunity to interference on the microphone cable and as a result t

A ‘Y’ lead may be required to connect to equipment with separate send and return jacks as shown below: Stereo Inputs STEREO 1/2 These accept 3-pole 6.35mm (1/4") jacks, or 2-pole mono jacks which will automatically ground the ‘cold’ input. Use these inputs for sources such as keyboards, drum machines, synths, tape machines or as returns from processing units. The input is BALANCED for low noise and immunity from interference, but you can use UNBALANCED sources by wiring up the jacks as shown

Polarity (Phase) You will probably be familiar with the concept of polarity in electrical signals and this is of particular importance to balanced audio signals. Just as a balanced signal is highly effective at cancelling out unwanted interference, so two microphones picking up the same signal can cancel out, or cause serious degradation of the signal if one of the cables has the +ve and -ve wires reversed. This phase reversal can be a real prob- lem when microphones are close together and you

PROBLEM SOLVING Basic problem solving is within the scope of any user if a few basic rules are followed. • Get to know the Block Diagram of your console (see page 12). • Get to know what all controls and/or connections in the system are supposed to do. • Learn where to look for common trouble spots. The Block Diagram is a representative sketch of all the components of the console, showing how they connect together and how the signal flows through the system. Once you have become familiar with th

MONO INPUT CHANNEL 1 Mic Input The MIC input accepts XLR-type connectors and is designed to suit a wide range of BALANCED or UNBALANCED signals. Professional dynamic, condenser or ribbon mics are best because these will be LOW IMPEDANCE. You can use low-cost HIGH IMPEDANCE mics, but the level of background noise will be higher. If you turn the PHANTOM POWER on (top right-hand side of the mixer) the socket provides a suit- able powering voltage for professional condenser mics. ONLY connect con

The Send may also be tapped off as an alternative pre-fade, pre-EQ direct output if required, using a lead with tip and ring shorted together so that the signal path is not interrupted (see below). 5 Gain This knob sets how much of the source signal is sent to the rest of the mixer. Too high, and the signal will distort as it overloads the channel. Too low, and the level of any background hiss will be more noticeable and you may not be able to get enough signal level to the output of the mixer

POST-FADE), but for Foldback or Monitor feeds it is important for the send to be independent of the fader (this is called PRE-FADE). AUX SENDS 1 and 2 are both globally switchable between pre and post-fade (see master section on page 21). Aux 3 is always post-fade. 8 PAN This control sets the amount of the channel signal feeding the Left and Right MIX buses, allowing you to move the source smoothly across the stereo image. When the control is turned fully left or right you are able to route the

STEREO INPUT CHANNELS 1 INPUTS STEREO 1/2 These inputs accept 3-pole 6.35mm (1/4") jacks. Use these inputs for sources such as keyboards, drum machines, synths, tape machines or processing units. The inputs are BALANCED for low noise and top quality from professional equipment, but you can use UNBALANCED sources by wiring up the jacks as shown in the ‘Wiring Up’ section earlier in this manual, although you should then keep cable lengths as short as possible. Mono sources may be used by pluggi

7 FADER The 60mm FADER gives you smooth control of the overall signal level in the channel strip, allowing precise balancing of the various source signals being mixed to the Master Section. It is important that the input level is set correctly to give maximum travel on the fader which should normally be used at around the “0” mark. See the “Initial Setup” section on page 22 for help in setting the right level. 8 PFL When the latching PFL switch is pressed, the pre-fade pre-mute signal is fed i

Press the switch to enable the +48V power to all of the MIC inputs. The adjacent LED illuminates when the power is active. WARNING: TAKE CARE when using unbalanced mics which may be damaged by the phantom power voltage. Balanced dynamic mics can normally be
