Summit Audio MPC-100A

The MPC-1OOA is a single channel tube preamplifier and tube compressor/limiter accepting line, microphone, and Hi-Z input signals. Utilizing both tubes and solid state technology working in synch with the Jensen mic transformer the MPC-100A lends a detailed sound with harmonically complex overtones. The ultra-fast compressor is ideal of optimizing signals prior to entering the digital domain. Other features include impedance matching (loading) control on the Hi-Z input so passive guitars and bass pickups have a whole new level of tone control, true VU metering, and multiple outputs. And with three separate gain controls, you have endless tonal variations from clean to saturated for whatever sound you need.

• "Clean" to "Saturated" valve sounds
• Soft Clipping LED indicators
• HI-Z instrument input with impedance matching control
• Two stages of vacuum tube gain controls
• 3 Position attack and release controls
• High quality VU meter for output and gain reduction metering
• Continuously variable output level control
• +4 dB balanced and -10 dB unbalanced output
• Stereo linkable with a second MPC-100A
• Jensen mic transformer

• Output: +4 dBu corresponds to 0 VU. The output is balanced or unbalanced using 990 operational amplifiers. Output impedance is 75 Ω. The recommended output load is 600 Ω or more. Maximum output is +25 dBu.
• Input: The input transformer is balanced. The mic input impedance is 1500 Ω. The line level input impedance is 40 kΩ and the Hi-Z input impedance is one mega-ohm. The mic and line inputs are balanced and the Hi-Z input is unbalanced.
• Frequency Response: 5 Hz to 65 kHz
• Noise: Less than –80 dBu at unity gain from 20 Hz to 20 kHz
• Distortion: Less than 0.05% at +4 dBu from 20 Hz to 20 kHz
