[. . . ] This adjustment requires a small flat-blade screwdriver and has a travel of 270 degrees of rotation. When normal, in-phase stereo signals are applied to the MS Series unit, the PHASE indicator will glow green, with an occasional yellow flicker. If one channel is disconnected or reduced to zero, the color will change to steady red. It will also be mainly red for out-of-phase stereo. NOTE: Out-of phase stereo is not compatible with conversion to mono. The out-of-phase condition should be corrected, or there may be substantial level loss when left and right are summed to mono. 4 Digital Audio Monitoring On MS Series units equipped for digital audio, stereo digital signal(s) may be connected via the rear panel BNC connector(s) labeled AES1, and, if present, AES2. Only one connector is needed per stereo signal. The digital input(s) conform to the AES/EBU 75 ohm/BNC (AES-3id-1995) standard. Another standard, S/PDIF 75 ohm coaxial, may also be monitored. There are two Signal Present indicators for each BNC digital input. The indicator(s) on the rear panel are adjacent to the BNC connector(s) and are labeled SIG. The indicator(s) on the front panel are labeled AES1 (and AES2). Both front and rear indicators display identically. If the digital data is valid and signal is present, they will glow GREEN. If the data is bad or no signal is present, they will glow RED. Both analog and digital signals may be connected simultaneously. The meters, speakers, phase indicator, and headphone output will monitor the source selected with the A/D SELECT button, which toggles between ANALOG and DIGITAL, with indicator LEDs showing the chosen source. Analog Outputs The XLR balanced Analog Outputs on a MS Series unit need not be used. However, they provide a convenient, high quality balanced signal source, complete with their own SIG indicators to verify the presence of signal. There is also a stereo GAIN TRIM control on the rear panel which may be varied from -6 to +6 dB. The Analog Outputs are labeled Left and Right. With two-channel models, Channel 1 is assigned to the Left out and Channel 2 is assigned to the Right output. With four-channel models, output assignment switches (LEFT CHANNEL SELECTOR and RIGHT CHANNEL SELECTOR) are provided for maximum flexibility. They allow any channel to be routed to either output. [. . . ] (For non-video units only. ) Vary the BALANCE control from left to right and verify that the test signal moves from the left speaker to the right speaker (and left headphone channel to right headphone channel), following the slider's motion. This concludes the basic system check-out of the product, and it is now ready for in-rack placement. Should any of these tests not perform as indicated, please contact the Furman factory for help or service information. Three Year Limited Warranty The Furman MS Series Confidence Monitor System is warranted against failures due to defective parts or faulty workmanship for a period of three years after delivery to the original owner.
