RDL (Radio Design Labs) HR-MP2, HR-MP2A
Dual microphone preamp
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 6dB/octave low-cut filter with a -3dB cutoff at 80Hz. Two additional switches on each input select 24V or 48V phantom if the master phantom power selector is on. The input pad switch allows the operator to attenuate the input signal by 15dB prior to the preamplifier input stage, increasing the maximum input level from +5dBu (attenuator out) to greater than +20dBu. A polarity switch provides signal polarity reversal if needed. The gain control provides continuous adjustment between 20dB and 60dB.
