   Connectors(5) 3.5 mm captive screw connectors, 3 pole
   Impedance>10k ohms unbalanced, >20k ohms balanced, DC coupled
   Nominal level-20 dBV (100 mV), -10 dBV (316 mV), 0dBu (0.775 V), or +4 dBu (1.23 V); (configurable)
    NOTE0 dBu = 0.775 Vrms, 0 dBV = 1 Vrms, 0 dBV ≈ 2 dBu
+4 dBu and 0 dBu are professional audio line level standards.
-10 dBV and -20 dBV are semiprofessional, computer audio, and consumer audio standards.
   Maximum level+14 dBu, (balanced or unbalanced) at stated %THD+N
   Input gain adjustment–18 dB to +24 dB, adjustable per input (via RS-232/control software)
   Aux/Mix level adjustment-43 dB to +24 dB (adjustable only via front panel)
Audio output
   Number/signal type1 stereo or mono, balanced/unbalanced
   Connectors(1) 3.5 mm captive screw connector, 5 pole
   Impedance50 ohms unbalanced, 100 ohms balanced
   Gain error±0.1 dB channel to channel
   Maximum level (Hi-Z)>+21 dBu, balanced or unbalanced at 1% THD+N
   Maximum level (600 ohm)>+15 dBm, balanced or unbalanced at 1% THD+N
    NOTEAn unbalanced-wired output results in a 6 dB attenuation.  A balanced-wired output has unity (0 dB) gain/attenuation.

The Extron MLS 100 A Switcher is a compact, four-input stereo audio switcher. Inputs one through four provide unbalanced audio while an additional input is an active auxiliary line level mono audio input that can be mixed with any of the other four selectable inputs. When used with a TouchLink® Control System or MediaLink® Controller, input selection and volume control are easily achieved using RS-232 or the controller's user interface. Input selection can also be controlled using the MLS 100 A switcher's front panel buttons.

Housed in a quarter rack width metal enclosure, the MLS 100 A is ideal for installation in podiums and other space-constrained areas.

The CSR 6 Captive Screw to RCA Audio Adapter is available as an optional output adaptor, converting the captive screw output of the MLS 100 A to a pair of female RCA connectors.
