The AER dual mix is a high-quality, two-channel preamplifier for instrument/line or microphone signals. The unit offers simple, efficient features just like a small mixing console:
two inputs, each for one microphone or instrument
and line-level signal
with switchable 24V-phantom-power
separate active two-band EQ networks for each input
a 4-preset multi-effects-unit with two reverbs,
one echo and one chorus
a stereo aux-in
line-out and DI-out
plus a stereo-headphone-preamplifier
Switchable microphone or line input Combo socket, XLR and 1?4œ jack (6.35 mm)
Line mode (jack input) Unbalanced high impedance input for instrument pick-ups and line-level sources Gain adjustment range: +3...+20 dB Min. input voltage: 100 mV (“20 dBV) Max. input voltage: 3 V (+10 dBV) Input impedance: 2.2 M? || 60 pF Signal-to-noise ratio, A-weighted Min. gain: 108 dB Max. gain: 98 dB Frequency response: 20 Hz...20 kHz / ?1 dB THD + N (1 kHz): < 0.3%
Mic mode (XLR input) Balanced microphone input 1 = ground, 2 = positive (+), 3 = negative (“) Gain adjustment range: +4...+40 dB Min. input voltage: 10 mV (“40 dBV) Max. input voltage: 3 V (+10 dBV) Input impedance: 2.1 k? Unbalanced:1.1 k? Signal-to-noise ratio, A-weighted Min. gain: 108 dB Max. gain: 93 dB Frequency response: 20 Hz...20 kHz / ?1 dB THD + N (1 kHz): < 0.1% Phantom power: 24 V, R = 1.2 k? per terminal, switchable for each channel, total current max. 10 mA per channel, short circuit protected Warning: External equipment may be damaged by inappropriate use of phantom power. In case of doubt keep the 24 V phantom power switch off (not pushed).
