REAR PANEL JACKS:

33.

MIC INPUT: 

XLR low impedance input jacks that will accept a wide range balanced input. Pin 2 is the positive 

phase input.

34.

LINE INPUT:

Left/mono and right 1/4" (TRS), high impedance, balanced input jacks. The left/mono jack (if used 

alone) automatically sums to the left and right inputs.  The tip is the positive input and should be used for
unbalanced applications.

35.

SIDE-CHAIN INSERT:

Left and right 1/4" stereo (TRS) jacks which allow an external device or another audio 

input to be inserted into the detector’s signal path to control the VCA circuitry. The tip has the send signal; the
ring is the return input. A switch in the jack normally connects the return (ring) to the send (tip) until a plug is
inserted. This jack is enabled by a front panel switch (see #16).

36.

MAIN OUTPUTS:  

Both balanced XLR and unbalanced 1/4" jacks are provided to interface with any type of 

equipment. The XLR connectors have 4 dB more output to match the +4 dBu industry standard level. Pin 2 
(and Tip) is the positive phase.

37.

TRACK INPUTS:  

Unbalanced left/mono and right 1/4" input jacks that feed the track level control. The 

left/mono jack (if used alone) automatically sums to the left and right inputs. This is where the computer output
or sync track is connected for track monitoring while laying down new tracks.  

38.

AC MAINS INPUT:

Connect the line cord to this connector to provide power to the unit. Damage to the 

equipment may result if improper line voltage is used. Operate only with the specified AC input voltage and
frequency applied.
