[. . . ] Does your keyboarder need a preliminary mix of his synthesizers on stage? [. . . ] An effects loop with stereo return for all input channels is included as well -- with a control knob for each channel, of course. The balanced microphone channels have a top quality 2-band EQ for bass and treble plus an input gain control on the units back side. With a signal-to-noise ratio of > 97 dB and a frequency response of 4Hz ­ 20KHz, noise isn't an issue and signals pass through the mixer without losses. The MLM 62 is especially for solo acts and PA, club & restaurant situations, where there is little space to mix your equipment. Compact design, excellent technology and outstanding audio properties -- and all for the price that you would ordinarily pay for a large package of high-quality cables. · 2 mic/line in + 4 line in channels · 2 output channels (stereo/mono) · 1 effect send + 2 eff.
