MP-1A mic-pre amp
EQ-1A equalzier
CL-2A compressor | Dual input all tube mic preamp. 48V Phantom power and 1/4" DI/XLR inputs. | A complete front-end, includes an additional direct instrument (DI) input as well as a separate line input. The microphone input has switchable loading impedance, phantom power, phase reversal and a –20 dB Pad. All inputs are equipped with a low-cut filter. The 3-band optical compressor is designed to maintain optimum summing of all three bands with a remarkably flat frequency response. A bypass switch shorts out the whole compressor. Mic. Input/Output are balanced and have fully floating transformers with a static screen. The Line Input is unbalanced, but an optional transformer is available. The power supply and the sidechain circuits are based on a solid state circuit. With the exception of the output stage all DC voltages are stabilised. Features • Mic. Gain in 2 dB and 10 dB steps • Selectable mic. impedance 600/1200/2400 • Phantom Power (+48V) • Phase reversal • 20 dB pad • High impedance Direct Input • Separate line input (gain +/- 10 dB) • Lowcut filter (20 Hz / 40 Hz/off) • Optical gain reduction elements • Cont. variable Threshold, Attack, Release • Ratio 2:1 to 10:1 • LED display showing gain reduction • Low, Mid, High Output Gain: off to +10 dB • Variable X-over frequencies • Low noise < -80 dBu @ 0 dB gain • Master Output Gain: off to +10 dB |
