Ever since the early 90's, the Manley ELOP® stereo electro-optical limiter has been used to control the dynamics of countless recordings and has delivered the classic tube sound that Manley Labs is famous for. This LA-2A type device can handle a lot of limitation without loss of high frequencies.

New model

Compared to the first version from the 90s, the current model has been updated with a more up-to-date power supply, which ensures a lower noise level and a new 3: 1 compression ratio, which provides greater usability.

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 the 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 increase 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
