TOA's MP-1216 Multi-Channel Monitor Panel is an active device featuring aural and visual monitoring of up to sixteen channels for any combination of speaker and line level audio circuits. By linking two MP-1216's up to 32 channels may be monitored. The unit may be located away from the equipment, allowing remote monitoring of system levels. It requires only standard, light gauge audio cable for connection to points in the system to be monitored, whether they are speaker or line level. The MP-1216 is highly useful for monitoring signal levels in any system with multiple channels of line level feeds and/or amplification. This is particularly true when equipment provides, at best, only clip indicators or where there is a variety of different types of indicators-all calibrated to their own "standard" level. This can present a very confusing "level picture", even to trained operators.
A major feature of the MP-1216 is that there is a 12 segment LED meter for EACH input. The meters are active at all times so that all levels can be SIMULTANEOUSLY monitored. The meters are calibrated for 0.3W to 1,200W for 8 ohm speaker circuits and -30dB to +6dB *(ref 0.775V) for line level circuits. Each input is bridging, transformer isolated and can accept signals from high or low impedance speaker or line level circuits. Each input has a separate screw terminal for each type of input. This provides positive, hardwired, reliable connections with no input switches to misadjust or fail. Because of the transformer isolation and high impedance inputs, by connecting one channel to a patch bay jack, any audio signals in the patch bay can be safely monitored— even mic signals (although usually only at low aural levels).
