The MX51 is a four channel mixer designed for Audio Visual and Aerobics applications. Channels 1 and 2 have 1/4" inputs, Channels 3 and 4 have dual RCA jacks mixed to mono. Channel 2 has both RCA and 1/4" inputs. The unit also features a headphone output that will drive up to 600 Ω headphones with full frequency response. The MX51 is intended for professional applications and has an FR4 glass epoxy circuit board and vinyl laminated steel chassis. All inputs are mono - although the RCA inputs appear to be stereo, the signals are mixed to mono in order to have all signals present for A/V or aerobics applications where stereo amplification is not desirable. DESCRIPTION DC PWR: For connection to the power supply. OUT: Stereo RCA jacks (mono signal) for connection to a mixer or amplification device. CH 4 and CH 3 INPUT: Stereo RCA jacks for connection to a signal source such as a CD player, cassette deck, tuner, etc. CH 2 INPUTS: Stereo RCA and one 1/4" jacks (paralleled) for connection to a signal source such as that mentioned for Channels 3 and 4, or to a source such as a wireless microphone or instrument. CH 1 INPUT: 1/4" unbalanced jack for connection to a source such as a wireless microphone or instrument. LINE/HEADPHONE OUTPUT: 1/4" Stereo jack for connection to a mixer, amplifier or stereo headphones. CH 1 - 4 LEVEL: Adjusts the volume level of each channel. OPERATION To operate the MX51, properly connect cords from the sources to be mixed (wireless mics, cassette decks, CD players etc.) into the channel inputs. Connect the outputs to an amplification device or sound system. Adjust the channel level controls for the desired volume. For private listening, plug stereo headphones into the LINE/HEADPHONE OUTPUT on the MX51 front.
