• The HR-MP2 is a dual channel microphone preamplifier with line-level outputs
• Each section provides identical rear-panel signal connections and front-panel controls
• Each preamplifier is equipped with a front-panel FILTER switch to enable or disable a 6 dB/octave low-cut filter with a -3 dB cutoff at 80 Hz
• Two additional switches on each input select 24 V or 48 V phantom if the master PHANTOM power selector is ON
• The INPUT PAD switch allows the operator to attenuate the input signal by 15 dB prior to the preamplifier input stage, increasing the maximum input level from +5 dBu (attenuator out) to greater than
