Manley ELOP+ Stereo Electro-Optical Limiter  From Manley

10:1 Limiter and 3:1 Compressor ratios

All-tube audio path uses 5751 (gain) and 6922 (White Follower Output) dual triodes each channel

Balanced Manley IRON® transformer-coupled XLR Inputs

XLR impedance-balanced outputs

BYPASS switches and AUTOMUTE with warm-up delay

Large illuminated VU meters read Gain Reduction or Output levels

STEREO LINK

Side-Chain High-Pass Filter

Standby Power Consumption: 0.5 Watts

Universal internal power supply operates worldwide 90-250V~AC 50/60Hz

ALL-TUBE audio path using a 5751 for gain, 6922 White Follower output tube (one each per channel)

Silent Conductive Plastic GAIN control.

Balanced MANLEY IRON Transformer coupled XLR input.

Input impedance: 14 kOhms

Maximum input level: +18dBu or 4.8V RMS @ 0.01% THD

Hi-current White Follower Impedance Balanced XLR output.

Output impedance=150 Ohms

Maximum Output with 100 kOhm load= +30dBu @.009%THD+N, BW 22Hz-22Khz, 1Khz sine

Maximum Output with 600 Ohm load= +20dBu @.015%THD+N, BW 22Hz-22Khz, 1Khz sine

Output Headroom (Referenced to +4dBu)= 26dB

Frequency Response= -0.15dB @ 10Hz, -0.1dB @ 20KHz

Total Harmonic Distortion (1kHz sine @ +4dBu, BW 22Hz-22kHz) = 0.004 % THD+N

Noise Floor Limiter Bypass= -90dBu (BW 22Hz-22kHz)

Noise Floor Limiter Engaged= -88dBu (BW 22Hz-22kHz) Input set to Unity gain

Dynamic Range= 118dB

Signal to Noise Ratio = 92dB (Referenced to +4dBu)

Bypass mode = Signal goes thru ALL-TUBE audio path (Bypasses limiter) this is not a “hardwire bypass”

Unity Gain= Set Input Attenuator @ 1:00 o’clock

Maximum Gain= 13 dB

Common-Mode Rejection Ratio (CMRR)= 77dB (BW 22Hz-22Khz, +4dBu, 1Khz sine)

Limiter Ratio= 10:1

Compressor Ratio= 3:1

Limiter: Attack= 15ms

Limiter Release= 200ms

Compressor: Attack= 75ms Release= 200ms

Attack/Release times measured under following conditions: 4dB of Gain Reduction, 1kHz sine, +4dbu Input level, to 63% of total.

Attack times are faster with higher input levels and heavier gain reduction. Typically for complete release, release times increases up to a couple of seconds, depending upon the amount of previous reduction.

Maximum Limiting (with +4dBu 1Khz sine)= 12dB

Maximum Compression (with +4dBu 1Khz sine)= 6dB

Side-Chain High Pass Filter= 80Hz (Internal user adjust jumper to 150Hz)

Automute warmup delay=30 seconds

Operating mains voltage= 90 to 254 VAC (internal universal power supply)

Mains voltage Frequency= 50-60 Hz

Power consumption= 26 Watts

Dimensions= (w,d,h) 19" x 7 x 3 1⁄2" (occupies 2u)

Unit weight= 9.5 Ib

Shipping weight= 10 Ib
