The MP1a is a manual controlled MIC PRE with an output level control Recent studio demos have yielded the following test results:
So far, all of the engineers that have used the MP1a have said that it has a very WARM low end similar to "my past" and the high end seems more open and has more "dimension". The TILT control seems to be a hit.
Gain control gain range: 35dB without PAD, 55dB with the pad
Minimum gain thru mic pre: 17dB (includes the input transformer and output transformer)
Maximum Gain thru Mic Pre: 55 dB
Maximum input level: 11.5 dBu @ 800Hz
Typical Distortion: .2% @ 50Hz, .019% @ 800Hz, .016% @ 20KHz -10 dBu IN
Output Clip Level: +29dBu
Input Pad: -20 dB
Input Impedance: 1500 OHM Bridging, for a 150 OHM Mic SourceThe MP1a has a unique feature with the gain control. Unlike most mic preamps, the MP1a can bring the amplifier down to UNITY gain instead of the minimum +6 db of gain with others. This is very useful with drums, giving you 6 more dB before having to switch in the PAD.
