The INPUT LEVEL control is an input aenuator. It funcons like a variable
pad. It acts on the Direct In (DI), Mic and Line inputs. Fully counter-
clockwise is o, and clockwise rotaon increases the level.
With the gain switch set to LOW and the input level set fully clockwise the
MIC input will yield about 40dB of gain and the LINE input will produce
20dB of gain.
The top label of the selector switches show operaonal status when the
buon is pushed in and illuminated.
MIC/LINE selects either the MIC XLR input or it selects the LINE XLR or
DI 1/4 “ inputs.
The 120Hz high pass lter posion is useful for reducing breath “pops,” or
any me a reducon of LOW frequencies such as train or trac rumble or
air condioning rumble.
The HI/LOW gain switch adds 10dB of gain (or when the internal jumper
is set, 20dB of gain) to the circuit when engaged. For most applicaons, this switch can be in the LOW posion, but for low
output microphones or quiet sources, extra gain may be needed. (Note: If the internal 20dB jumper is used, noise oor will also
increase. See page 11 for instrucons on changing the internal gain jumper.)
48 Volt “PHANTOM” power is applied to the Mic input XLR when this switch is engaged. This should only be used for
microphones that require phantom power.
0 / 180 - The Mic phase switch inverts the signal by 180 degrees when engaged.
DIRECT IN, Instrument input. This 1/4 inch input jack is for use with guitars, keyboards, or any other instrument. When a plug
is inserted the CORE will automacally switch to the DI input. The Mic/Line switch must be set to the Line posion to acvate
the DI. This is an unbalanced 10 MegOhm input that will not load down Hi Z instruments such as a guitar. The connecons on
this TS Jack are TIP-HOT, SLEEVE- GROUND.
