Purple Audio Inc. MC76 Peak Limiter Effective with serial number 001 The MC76 is a Monaural FET Peak Limiting Amplifier Units of this type have been in wide use for many years to provide precise and automatic control of peak signal levels in recording studios, disc mastering facilities, broadcast stations and sound reinforcement applications. Operation of the MC76 Limiting Amplifier should be very familiar to those who have used similar devices in the past. UNITS FEATURE: *Discrete Transistor Electronics *Transformer Balanced XLR Inputs and Outputs *Zener Shunt Regulated Power Supply *Single Element Class A Output Amplifier *Compression Ratios 4:1, 8:1, 12:1 and 20:1 *Fast Attack Time 20 microseconds to 800 microseconds *Release Time 50 milliseconds to 1.1 second *Gain 45dB (full gain with no limiting) *VU Meter for output level and gain reduction indication *Built In Stereo Interconnect with offset adjustment *Heavy Gauge Stainless Steel Enclosure *Purple Anodized Aluminium Front Panel *120/240 volt operation *3 Year Warranty UNPACKING AND INSTALLATION Your MC76 was packed with care at the factory. The packaging was designed to protect the unit from rough handling. However, once the unit leaves us, it may pass through the hands of those who have no idea what is in the box, may not be happy with work, may like to throw things, don't care... etc. Despite the heavy duty carton and foam blocks the unit was packed with, we recommend you inspect the box and its contents immediately for any sign of damage that may have occurred in transit. If there is damage, you should save all the packing materials and contact your vendor and shipper immediately. We recommend you keep the packing materials. Murphy's law states that once you throw away the box the likelihood you will need it back will increase in proportion to the square of the distance from your service center multiplied by the cost replacement packing of materials. The carton we ship out contains: *One MC76 Limiting Amplifier *This Manual *One six foot (two meters) IEC Cable *Warranty Card The unit can operate safely and within specification over a range of ambient temperatures from 0°C (+32°F) to +50°C (+122°F). Humidity is generally not a factor unless there is condensation. One way to avoid condensation is to keep the ambient temperature reasonably constant. The unit can be powered from either 100-125 volt or 200-250 volt AC Mains at a line frequency of 50 or 60 Hz. The operating voltage should be set BEFORE you plug the unit in. The power inlet module integrates the voltage selector into the fuse holder. The selected voltage (115V or 230V) will show through a small window in the flip down "door" that covers the fuse holder. The unit should be supplied with an IEC cable applicable to your locality. The fuses and voltage selection should be set up for you, BUT NEVER ASSUME!! Fuses: At 115 Volts the unit should be fused for 1/8 Amps At 230 Volts the unit should be fused for 1/16 Amps Signal C
