lower front and rear cover screws of a single unit, to raise and to tilt it for easy use. In

addition, one or more sets of vertical stacking plates, mounting to the upper front and rear

cover screws of the bottom unit, allow multiple units to be stacked. Several units can be

desk mounted side by side and even stacked side-by-side using horizontal joiner kits

together with mounting base and stacker kits. P/N20617-501 is the angled base kit.

P/N20617-502 is the base plus one stacker kit (two high). P/N20617-503 is the base plus

two stackers (three high). P/N20617- 504 is the stacker kit by itself and P/N20604-504 is

a horizontal joiner kit.

Detailed instructions for mounting the protection plates and battery pack slides are

included with the PROK-1 and ABAG-1 if they have not been pre-assembled to the

mixer.

AUDIO CONNECTIONS

XLR type inputs and outputs are wired per figure 1 with pins 2 as HI and pins 3 as LOW.

Pin 1 of all input connectors is grounded and is the cable shield and DC return connection

for phantom microphone power. Pin 1 of the output connector is grounded. Active

balanced outputs require a reference ground connection to the receiving device for proper

operation. This ground can be provided by the rack frame or a studio buss connection but

is preferably carried through by the output cable shield.

POWER CONNECTIONS

Hum and noise performance of the XP100 can be degraded by poor DC ground

connections between it and the MX100. Use of the recommended rack and desk

mounting kits will assure a good ground connection between units by firmly strapping

their chassis together. CAUTION! The outer shell of the DC interconnect cables is

positive relative to the chassis. Do not allow a DC cable plugged into a powered unit to

hang loose where it might short against the chassis or rack frame.

MAINTENANCE

There is no routine maintenance required. If you have a problem, check panel LED

indicators to assure that the units have DC power, eliminate by substitution microphones,

input and output cables, connectors, downstream devices, Mixer to Expander

interconnect cables and power supplies. If all else fails, read your warranty in the front of

this book (even though it probably ran out yesterday) and call us for sympathy and

overpriced parts.
