gain setting you achieve satisfactory results.
Be careful when you add HF gain because this also affects the overall gain structure of the preamplifier
and could introduce overload distortion. After you make this adjustment, you may need to reduce the
Input Gain control (ref. #3) correspondingly to compensate for the HF signal boost.
Specifications
Electronic
• 80 dB of gain at 1kHz, balanced-in to balanced-out
• Noise figure, rms A-weighted:
• Noise figure, rms unweighted:
• EIN
• Frequency response: -3dB 200 kHz
• THD:
• Balanced Microphone Input Impedance > 10 k
Ω
• DC-coupled inputs are protected from external P48 phantom power. If phantom power is applied, the
input circuit shuts down until the phantom power is removed.
• AC-coupled inputs with switchable full-spec P48 phantom power; 10 mA per channel available under
any load condition
• Input Gain control: twelve-position switch provides from +7 dB to +55 dB of gain for the preampli-
fier circuit, as measured between the input and the unbalanced output; the balanced output is +6dB
