LINE INPUT LEVELS Adjust for the desired sound level from the sources connected to LINE IN 1 and 2. MIC INPUT LEVEL Adjust for the desired microphone sound level. OVERLOAD INDICATOR LED flashes when the internal compression circuits are protecting the amplifier output against overload. It is normal for this indicator to flash during high audio levels. Reduce the input level if this indicator flashes excessively or stays on continuously. TONE CONTROLS Adjust for desired sound without causing amplifier overload. POWER INDICATOR Glows blue when the product is connected to a valid power source. 20 WATT STEREO AUDIO MIXER AMPLIFIER RDL® EZ-MXA20 MICROPHONE IN OFF ON RDL® EZ-MXA20 24 VDC 8Ω 4Ω LINE IN 2 LINE IN 1 R SPEAKER IMPEDANCE COMPRESSOR IMPEDANCE SELECTOR Set to match the speakers connected: 8 Ohm: Button OUT 4 Ohm: Button IN LINE INPUTS Connect a line-level source to LINE IN 1 and/or 2.
