M606

The M6O6 audio amplifier is an ac operated , plug-in unit designed to provide 6 watts output power to drive loudspeaker for cue, announce booth and similar utility applications FEATURES: 6w rms direct output into 8 ohms The circuit utilizes differential operational amplifiers to produce an ultra-reliable transformerless design capable of driving an 8 ohm loud- speaker directly. Other Ioad impedances (4, 16 ohms, etc.

are permissable with the appropriate power output interpolation Compact design mounts in standard WBS 3 inch MF6 rack frame A combination of conditional frame strapping and variable front panel level control permits the M6O6 to operate over an input signal range of ~2OdBm to +18dBm Self contained power supply The M606 presents a permanent 2Ok ohm impedance at the input and is capable of operating from a balanced or unbalanced source.

The unit exhibits exceedingly uniform frequency response with low noise and distortion over the frequency range 30Hz to 20kHz Operational amplifier transformerless 1C design 20K bridging input The modest size of 1.ZW x 3.4H x 13.7D inches allows ten M606 utility amplifiers to be accommodated in one standard rack mounting (19W x 3.5H) MF6 equipment frame_ Active elements contained on plug-in subsidiary PC card
