Visual Monitoring The MVXA Series efficiently monitors from -30dBV (line level reference) to 200Vrms (100Vrms reference). Units are capable of monitoring any combination of 25V, 70V, 100V, or line level signal inputs (Signal type of each channel is individually set using adjustable jumpers). All channels can be visually monitored simultaneously as each signal has its own twelve segment LED bargraph that provides 33dB of resolution. The bottom ten LEDs are green and have VU ballistic response for -30dB to -2dB. The top two red LEDs have peak response characteristics for 0dB to +3dB above reference level to provide easy identification of critical signal levels. Audio Monitoring Audio monitoring methods include: An internal speaker, a headphone jack, a 3 Watt speaker output for connection to an external speaker, and a line level output for connection to an amplifier. Isolation Both MVXA models feature Atlas Sound's exclusive CerAmpTM technology (patent pending) to isolate noise from the input channels. Our CerAmpTM design utilizes ceramic capacitors and an op-amp to achieve high input impedance isolation without transformers to reduce distortion, hum, and noise. Mounting Flexibility The compact design of the MVXA is ideally suited for shelf, rack, or wall mounting. To facilitate application flexibility, rack mount brackets may be installed in three different ways for standard rack or wall mount applications including single and side-by-side wall orientation.

Remove Rear Panel Cover and set jumpers for each input to desired reference level (25V, 70V, 100V, or line level). Set Each Channel's 0dB Reference Level 25V 70V (Default Setting) 100V Line Level Place jumpers lengthwise only as shown in these diagrams! Jumpers must be adjusted before applying power!

Each channel is independent so that signals of different types can be monitored on the same unit. 2. Rack mount (if desired). Assure proper "Earth Ground"- see paragraph Shields and Grounding located in Back Panel View on page 6 for detailed information. 3. Connect each piece of equipment to be monitored to a separate + & — input terminal (channel 1-8 or 1-16). 4. Determine desired audio monitoring method and action. METHOD ACTION A. Internal Speaker No Action Required. B. Headphone Jack Plug in headphone. This automatically bypasses the internal speaker. C. External Speaker Connect external speaker to + and – speaker out terminals. If listening to both internal and external speakers is desired; keep the speaker/headphone disconnect jumper in the "on" position. If only the external speaker is desired; move the speaker/headphone disconnect jumper to "off". D. External Line Level Connect line level source to + and – line level out terminals. If listening to both the internal speaker and line level device is desired; keep the speaker/headphone disconnect jumper in the "on" position. If only the line level device is desired, move the speaker/headphone disconnect jumper to "off". 5. Perform desired wire management and labeling functions....
