Description
Passive monitor panel Model MP-1B offers 12 x 1 selectable
visual and aural monitoring. All twelve channels accept
speaker level inputs (8 ohm or 0-70 volts) for monitoring
amplifier outputs in large sound reinforcement systems.
Visual monitoring with precise measurement of selected
speaker input is accomplished using an analog meter with
VU and voltage scales. Subjective aural monitoring of selected speaker input is accomplished through the quality 3" x 5"
internal speaker which may also be accessed using the
monaural headphone output (stereo jack) on the front of the
panel.
Model MP-1B front panel features an analog meter with VU
and voltage scales, headphone jack and four control knobs
for easy selection of monitored system inputs (1-6, Off,
7-12), individual speaker level inputs (1-6), individual speaker level inputs (7-12), and volume of selected input.
Rear panel termination for input connections is made to barrier strip screw terminals which are group selectable for
speaker level inputs 1-6 and 7-12 (70V, 25V or 10V for
8ohms). Rackmount chassis is sturdy steel construction finished in durable black powder epoxy. Overall size is 19”W x
3.5”H (2RU) x 5.5”D.
