ESI ESP1010 - Manual (Page 18)

ESP1010
You can control gain from -60dB to +15dB (0.5dB per step) on input ch
1/2. Input 1/2 allows you enable +12V phantom power when using a
micrpphone. To use it, you must change the input level to “M”
(microphone) from “L” (line input). After selecting “M”, you can select “12”
(12V) on each channel for phantom power. Note: if your microphone
requires 48V phantom power, you can enable that on the hardware when
an optional external power supply is connected to the ESP1010 rack. It is
not recommended to enable both +12V and +48V phantom power
simultaneously.
2) OUTPUT: You can change the output monitoring level for all channels
(1~8, S/PDIF) by clicking and dragging the fader bar. The number on the
bottom shows the relative amount in dB. Clicking this number enables
you to mute the channel.
