Page 6: Control Panel Instructions
Control Panel Instructions 1. The Balanced Input Connectors of Channel A & B Balanced XLR signal inputs of Channel A & B to connect microphones, line signals, etc. Each channel is completely individual. The Gain Control Knobs of Channel A & B Each channel features a rotary gain control for variable adjustment of the desired pre‐amplifier level. 3. The Peak Indicator Light Each channel has an individual peak indicator light, which indicates the distortion. Twinkle continually means approaching the peak, while lasting illuminated means reaching the peak and the gear overloaded. 4. The Power Indicator Light The power indicator of on/off. 5. - Page 7 Step 2 Make a connection from the corresponding channel output on the front of the M3R to your desired destination (Mixer, recorder, etc). Step 3 Adjust the variable gain control to the desired pre‐amplified level. To ensure you do not over pre‐amplify your signal a peak clip indicator light has been provided on the front panel of the M3R for each channel. When illuminated, this light indicates that the preamplifier is overloaded and that distortion will occur. Please turn down the variable gain control for the currently selected channel until the peak clip light is no longer illuminated. Always trust your ears; the Peak LED is after the gain control so you could actually distort the input with a very high level. ...
