INPUT EXPANDERS
The companion
XPS100 Input Expander provides four XLR microphone/line
inputs with pan pots and switched phantom power. The
XPS200 Stereo Line
Input Expander controls two stereo -10/+4 XLR line level sources with tight
tracking stereo VCA level controls. The XPS100 and XPS200 are supplied with
interconnecting expansion cables for the audio and DC connections to the
MXS100, MX200 or MX200C.
POWER
A MXS100, MX200 or MX200C Mixer and a pair of companion Expanders can
comfortably share a single WA100-1, 24VDC / 400mA. wall mount power supply.
220VAC and 50Hz power supplies are available for offshore use. The Mixers can
also be powered directly by a PPA-1 rechargeable 24VDC battery pack or by a
DCA100 DC to DC step-up converter connected to 6 to 18VDC automotive, belt
packs, NP1s or 12V gel cell batteries. The PPA-1 and DCA100 can both mount
to the mixer chassis as an integrated system.
The BBU100 is a replaceable 9V battery pack that can be quick change, slide
mounted with the PROK-1 accessory.
MOUNTING
Accessory protective side plates (PROK-1) extend past both front knobs and rear
connectors and will allow no damage to the unit. The PROK-1 includes quick-
change slides for the battery and converter modules. An attractive protective
carrying bag with shoulder strap is available (ABAG-1) and includes the PROK-1
protection plates. Up to three NANOAMPS will mount side-by-side in only one
rack unit using the available rack mounting kits. NANOAMPS may also be neatly
stacked or mounted side by side on your desk with the available angled desk
mounting kits.
CIRCUIT DESCRIPTION
The input stages of the MXS100, MX200, MX200C and XPS100 are identical.
They are designed around a very low noise and low distortion, balanced and
floating input, instrumentation amplifier. The SSM2017 is one of the latest
generations of devices designed specifically for use as a low noise microphone
amplifier. In addition to ultra low noise and distortion, it boasts a very high slew
rate of 17V/
µs virtually eliminating slew induced Transient Intermodulation
Distortion. The direct balanced low noise inputs eliminate the need for input
transformers and avoid their distortion, transient overshoot, roll offs and
microphonics. The input preamp stages can operate at a MIC gain of 30, 40 or
50dB as selected by an individual jumper plug for each input. To access the
jumper plugs, remove the four cover screws (top two on each side) and pull the
top cover up and off. For 30dB operation, remove the gain jumper plug
completely or plug it on to only one pin for safekeeping. The preamps have a
