BACK PANEL All the connections on this page our found on the back panel of the mixer PHANTOM POWER switch This switch activates and deactivates the Phantom power on all the microphone inputs. Most condenser microphones require phantom power, which is a lower DC voltage delivered to the XLR microphone connector. MAIN OUTPUT 6.35mm (¼") SOCKETS These ¼" output sockets provide balanced or unbalanced line-level signals.
SPEAKON™ SOCKETS AND SPEAKER TERMINAL POSTS - These speakon™ connectors or Terminal posts are the output of the built in power amplifier, (see spec table for model and Wrms). IMPORTANT: Do not connect both speaker types at the same time doing so can damage the built in amplifier. Make sure that the impedance of the speakers are never less than 4Ω (ie 1x4Ω or 2x8Ω in parallel), otherwise the power amplifier may become damaged. Make certain to always use only power cables for speakers (1.
FRONT PANEL All the various controls will be described in this manual in sections. So before you start to read what each piece of equipment does find it first in the mixer. The manual will be starting in the top right hand corner beginning with MIC1 and working its way down the channel. MIC 1 - The mic input accepts a balanced or unbalanced XLR plug and can also accept a balanced or an unbalanced 6.35mm (¼") jack plug.
EQUALISER. HF,MF, LF There are 3 dial controls to the equaliser, these are HF (high frequency above 12kHz), MF (medium frequency around 2.5kHz) and LF (low frequency below 80Hz). All dials can be turned to the centre-detented position when they are not required to change the signal levels of that particular frequency. HF EQ - Turn to the right boosts the signal by up to +15dB, move it to the left to lower the signal by up to -15dB.
right. In the middle, at the 12 o’clock position, the sound in each channel is evenly distributed. MUTE - Mutes the sound from the main mix and redirects it to the sub group faders 3-4. MUTE LED - This illuminates to indicate a muted channel. The mute switch breaks the link to the pre channel fader. This signal is then set to post-fader to the sub group so the channel can still be heard separately from the rest of the channels on the mixer.
STEREO AUX RETURN SOCKET BALANCED/UNBALANCED 6.35mm (¼") SOCKETS AND LEVEL BUTTON A stereo signal input via both left and right 6.35mm (¼") sockets. Same as the other channels on the mixer accept this channel can work in stereo. If you wish to run in mono connect the left jack plug only. The Level button is used to switch between two settings to match the audio levels. The professional level is considered to be +4 dBu. The homeowner level is −10 dBV. Pressing the button will give you one or the other state.
PHONES 6.35mm (¼") SOCKET Connect headphones to the mixer via this socket so you can listen to individual channels, change settings and listen to them separate from the audio signal being played. AUX SENDS DIAL AND SOLO SWITCH - Controls the gain of all the AUX busses and sends the signal to the AUX OUTPUT. FX DIAL AND SOLO SWITCH - Controls the gain of all the FX busses and sends the signal to the FX OUTPUT.
STEREO AUX RETURNS DIALS The STEREO AUX RETURN 1 control determines the level of signal in the main mix. If STEREO AUX RETURNS 1 is used as effects return, this will determine the level effect when mixed with any “dry” channel. Note: when used this way, the effect device should be set at 100% effect. The right hand dial is there to add an effect to a monitor mix. FX DIAL AND MAIN MIX / ALT 3-4 SWITCH Works similar to the STEREO AUX RETURN.
MIX fader to lower the signal levels. Signals may be distorted if the signal levels are set to high. ALT 3-4 outputs are unbalanced and carry the signal of the channels that you have assigned to this group using the mute switch. This can be used to route a subgroup to a further mixing console for example, or used as a recording output working alongside the main output. MAIN MIX FADER - The faders are used to control the overall signal levels from all channels.

Cable connections You are going to use a large amount or cable that run to and fro from your console and have different plugs connected. When running your cables please make sure all cables are out of the way of where people may be walking. Damaged cables or your console being pulled off your workstation by cables being pulled on may damage the console. Here are diagrams on how to wire different plug connectors.
