Gain range selector (GAIN). Use this to select the appropriate gain range.
This selector can be thought of as a "pad" although it does not have
any sonic impact as can happen with a conventional pad circuit. Normal
microphone gain range (1.dB to 4dB) is selected when the indicator
is ON. Low gain range (.dB to 2dB) is selected when the indicator is
OFF.
Phantom power selector (48V). Phantom power (+48VDC) is activated
when the 48V indicator is illuminated. Avoid selecting phantom power if
you are using a ribbon microphone. While not required, it is advisable to
deselect 48V when using a dynamic microphone or a DI input.
Gain Control is used to set the appropriate gain range. Normal micro-
phone gain range is 1.dB to 4dB.
Use these to match signal level between the P2analog and devices to
which it is connected and to avoid overloading the preamp.
• SIG indicates that a signal is present on the channel. It illuminates
when the signal level exceeds 24dBu.
• +4 illuminates when the signal reaches normal operating level of +4
dBu.
• OL illuminates when the signal level exceeds +2 dBu, which is  dB
below the overload point for the P2analog (+1dBu). Maximum out-
put level in the low gain range is +2dBu.
• Note that the high level of the P2
bility of some devices (check manufacturer's specifications). In such
cases it is appropriate to use the intermediate level indicators (+1,
+18, +21, +24) to set the maximum output level of the P2
to match the maximum input capability of the connected device. In
other words, it is possible to cause overload distortion in the con-
nected device even though the P2
show a red light.
