• NOISE LEVEL: 70db below +4 dbm
• LIMITING NOISES: Below audibility
• INTERMODULATION OR HARMONIC DISTORTION: Less than 1% at any level up to + 18 dbm output (no limiting) Less than 1% at db limiting +12dbm output
• ATTACK TIME: .2 milliseconds on positions 1, 2 and 6 .4 milliseconds on positions 3,4 and 5 (adjustable)
• RELEASE TIME: Position 1: .3 sec Position 2: .8 seconds Position 3: 2 seconds Position 4: 5 seconds Position 5: Automatic function of program material: 2 seconds for individual peaks. 10 seconds for multiple peaks. 25 seconds for consistently high program level.
• COMPRESSION RATIO: A function of the amount of limiting as well as setting of the two threshold controls which can be set to operate at ratios from 1:2 to 1:30
• POWER REQUIREMENTS: 115 volts, 50-60 cycles AC, 3 amps.
• STABILITY: Unit maintains stability of gain, gain reduction and balance over the range of line voltage fluctuations from 100 to 127 volts.
