In addition, the SLE 82 features an effects loop with stereo return -- with a rotary control for each channel, of course. And because good racks are expensive and space in them is always in short supply, we fit all of these features into a 1U 19" housing. With a signal-to-noise ratio of >97 dB and a frequency response of 20 Hz ­ 20 KHz, noise isn't an issue and signals pass through the mixer without losses. · 4 stereo channel pairs with a total of · · · · 8 inputs and 2 outputs Effects loop with stereo return, adjustable for each channel Volume and balance controls for each input channel pair Master volume Signal-to-noise ratio > 97 dB [. . . ] [. . . ]
