being connected and the Tape In Level Control (18), so care must be taken in adjusting these levels so as to achieve proper balance in the final mix and to prevent overload distor- tion. The LED Output Metering Indicators (19, 20) can be used to maintain proper levels in the master mix. The L/R Normal LED Indicators (20) will light to indicate normal operating levels and you should always try to keep your levels within this range. Overload is indicated by the L/R Peak LED indicators (19). The Peak LEDs will light when the master mix is going into overload. It detects the peak level and will illuminate at 3dB before clipping to warn that the signal is approaching overload. You do not want the Peak LED to light except very intermittently during a take or a mix. If it does light persistently, reduce the master mix gain with the Master
Mix Gain Control (17).

Check the power source for the proper voltage (115VAC or 230VAC) noted below the Power In Socket (29). Once you have connected the AC power cord to the AC power source and the AC Power In Socket (29), switch on your mixer with the Power On switch (27). The Power “ON” LED (13) will light up. Allow 1 minute after powering up for the system to reach equilibrium before setting input gains and other levels. You can leave the

If you are using a turntable in your setup it is a good idea to connect it’s ground to the Phono Ground Terminal (31) to avoid hum and/or possible shock.The

When using condenser mics, +48VDC can be switched globally on or off to the XLR mic inputs for all mono channels (also see MONO INPUT SECTION, MIC INPUTS). When this switch is in the “ON” position, the Phantom Power On LED Indicator (12) will light, and +48VDC will be provided between pins 2 and 3 of all the mono Mic input XLR connec- tors. If you don’t need phantom power, be sure to turn this switch to the “OFF” position.
[Note: It is safe to connect balanced dynamic mics or line level devices even if this switch is on, but connecting unbal- anced devices or devices whose transformers are center- grounded will cause hum or malfunctions. Shorting the +48VDC can also damage your mixer. Also, turn down the Master Mix control (17) to prevent possible sharp transient noise from damaging the speakers when turning the phantom power on or off.]
