Peavey SRC 4026 FC Line Input, Mic Input, Insert, Gain, Low Cut, Hi EQ, Hi/Mid EQ, Low/Mid EQ

		Channel Functions
1	1.		Line Input
			1/4" balanced (TRS) high-impedance input for high-level signals. The tip is the
			positive input, which should also be used for unbalanced inputs. This input is
			connected through a 10 dB pad to the Mic Input (#2). The two inputs cannot
			be used simultaneously.
	2.		Mic Input
2			XLR balanced low-impedance channel input optimized for a microphone or other
			low-level source. Pin 2 is the positive input. Because of the wide range of gain
			adjustment, signal levels as high as +10 dBu (2.45 V RMS) can be accommodated.
			This connector has 48V on pins 2 and 3 (pin 1 is the ground reference) when
			the phantom power is enabled. (See note on #23.)

3. Insert

1/4" stereo (TRS) jack allows an external device to be inserted into the signal path before the EQ. The tip has the send signal, the ring is the return input. A switch in the jack normally connects the send to the return until a plug is inserted.

4.	Gain
4	Varies the input gain to allow for a wide dynamic range. Proper adjustment of the
	input gain will maximize the signal-to-noise ratio. It should be set by depressing
	the PFL switch (#18) and adjusting for a 0 dB (+4 dBu) level at the L-R meters.

5. Low Cut

This is a low-cut filter with a corner frequency of 75 Hz used to filter out rumble, wind noise, breath thumps, stage noise and other low-frequency components

that rob power from the amplifiers and muddy the signal. The pre-EQ signals sent to the AUX sends are picked up after this switch so that the monitors can also benefit from this filter.

6. Hi EQ

A shelving type of active tone control that varies the treble frequency levels

±15 dB at 12 kHz. It is designed to remove noise or to add brilliance to the signal, depending on the quality of the source.

7.Hi/Mid EQ

A bandpass (peak/notch) type of active tone control that varies the upper mid-

range frequency levels ±15 dB at 3.1 kHz. This frequency is optimum for bringing out the clarity of a vocal mic without adding harshness or grit, or can reduce high frequency feedback.

8.Low/Mid EQ

A bandpass (peak/notch) type of active tone control that varies the lower mid-

range frequency levels ±15 dB at 250 Hz. A slight cut in this frequency will usually help a mic that has a proximity effect to become more intelligible in close talking situations. It will also be useful to solve common feedback problems.

9. Low EQ

A shelving type of active tone control that varies the bass frequency levels ±15 dB at 70 Hz. It will add depth to thin signals or clean up muddy ones.
