- Page 2 The MX200 and MX200C Stereo Studio Mixers retain the identical high quality audio performance of the MXS100. They are an excellent choice for use in studios, TV vans, and with the companion Expanders, makes a very powerful mixing system in only one rack unit (1 ¾”).

MX200, M X200C S TEREO S TUDIO M IXERS The MX200 and MX200C Stereo Studio Mixers are also three input stereo mixers with front panel selection of microphone or line input levels. Phantom power is internally jumper plug programmable to any microphone input.

In the LINE input switch position, preamp gain is unity and peak line level inputs of +18dBu are accepted with nominal inputs adjustable over the range of - 10 to +4dBu.

- Page 7 Line O utputs The output stages, A9 and A10, utilize a unique active balanced output driver IC, the SSM2142, The ICs sense whether the connected load is balanced and floating or is unbalanced due to either side being grounded. A balanced output load will be driven with equal and anti-phase levels on the HI and LO output lines.
- Page 8 1/8" TRS jacks, J7 and J8. The nominal output is +4dBu unbalanced through a 287Kohm source resistance to feed the current summing expansion inputs of the MXS100 or MX200. The paralleled jacks, J7 and J8, allow multiple Expanders to be looped together and into the MXS100. Internal jumpers can bypass the 287Kohm resistors to allow direct use of the Expander outputs for low impedance loads down to 600 ohms.

Page 9: Installation
The XPS100 and XPS200 come with an audio cable, P/N20612-2, a DC cable, P/N20602-1, and an instruction book. The MXS100 comes with an instruction book and a mating 2.5mm T-S plug for the CUE input. The MX200 and MX200C only come with an instruction book. Mixers need either their own separately ordered WA100 power supply, a optional battery supply, a DC Converter or a DC cable, P/N20602-1 to share the supply of another NANOAMP. - Page 10 Rack and desk mounting hardware may be packed in with the unit even though ordered separately. Wall mount power supplies must be ordered separately but may either be included with the unit or shipped in their own box. Optional PPA-1 Battery Packs and DCA100-1 DC Converters may be shipped already mounted to the bottom of the Mixer or may be separately packaged so you have the fun of putting them together (only four #4 X 5/16”...
- Page 11 OUTPUT L EVEL, -‐ 10 t o + 8dBm If a different output level at 0VU meter indication is desired, drive the output to the desired output level at 1kHz as indicated by an external audio voltmeter connected across the output line and readjust METER CAL-LEFT and METER CAL-RIGHT trimpots for 0VU meter indications.
- Page 12 Battery cases slide in from the front and should click into place when fully inserted. Plug the battery cable into the rear connector of the mixer. The ABAG-1 Carry Bag wraps around the mixer and PROK-1 plates from below and mounts to the protection plates with the supplied four screws and washers inserted through eyelets in the carry bag.

An internal reference voltage equal to 1/2 the supply voltage is generated by A15 in the MXS100 and MX200 and by A7 in the XPS100. All IC inputs and outputs should show a DC level equal to this voltage when measured with a high impedance meter. - Page 14 Switch M aintenance The front panel MIC/LINE push-button switches have good wiping contacts and should need little attention. The switches are sealed and impossible to clean, in addition, most spray solvents will wash out the internal lubricant and cause premature mechanical failure.
