Lige siden de tidlige 90’ere har Manley ELOP® stereo electro-optical limiter været brugt til at kontrollere dynamikken på utallige optagelser og har leveret den klassiske rør-lyd som Manley Labs er berømt for. Denne LA-2A type enhed kan håndtere meget limitering uden tab af høje frekvenser.

Ny model

I forhold til den første udgave fra 90’erne er den nuværende model opdateret med en mere tidssvarende strømforsyning, som sikrer et lavere støjniveau og en ny 3:1 compression ratio, som giver større anvendelighed.

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

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.
