Preamplifier Specifications

Number of Channels
This is the number of channels the preamp is designed for.
1-Channel (Mono)
Phantom Power
This specifies whether or not the mic preamp has a phantom power supply.
Yes
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
10 - 50,000 Hz
Gain Range
This is the range of gain for the preamplifier.
12 - 52 dB
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
0.005%
Built-in Equalizer
Some preamps have a built-in equalizer to help process the audio. If the preamp has a equalizer, the type of EQ will be listed here.
3-Band Equalizer
