INSERT (Channels 1–6)

These jacks, on the back of the 1402-VLZ

PRO, are where you connect serial effects such as compressors, equalizers, de-essers, or filters . Since most people don’t have more than a few of these gadgets, we’ve included inserts for just the first six channels. If you want to use this kind of processing on Channels 7–14, simply patch through the processor before you plug into the 1402-VLZ PRO.

The INSERT points are after the TRIM and LOW CUT controls, but before the channel’s EQ and FADER controls. The send (tip) is low-impedance (120 ohms), capable of driving any device. The return (ring) is high- impedance (over 2.5k ohms) and can be driven by almost any device.

INSERT cables must be wired thusly:

	ring		SEND to processor
tip		(TRS plug)	“tip”
	sleeve
this plug connects to one of the			“ring”
mixer’s Channel Insert jacks.
			RETURN from processor

Tip = Send (output to effects device)

Ring = Return (input from effects device) Sleeve = Common ground (connect shield to

all three sleeves)

Besides being used for inserting external devices, these jacks can also be used as channel direct outputs; post-TRIM, post-LOW CUT, and pre EQ. Check out the 4-track hookup diagram . Here’s three ways you can use the INSERT jacks:

MONO PLUG

Channel Insert jack

Direct out with no signal interruption to master.

Insert only to first “click.”

MONO PLUG

Channel Insert jack

Direct out with signal interruption to master.

Insert all the way in to the second “click.”

STEREO

PLUG

Channel Insert jack

For use as an effects loop.

(TIP= SEND to effect, RING = RETURN from effect)

AUX RETURNS

This is where you connect the outputs of your parallel effects devices (or extra audio sources). These balanced inputs are similar to the stereo line inputs without EQ, Aux Sends, Pan, Mute, and Solo. The circuits will handle stereo or mono, balanced or unbalanced signals, either instrument level, –10dBV or +4dBu. They can be used with just about any pro or semi-pro effects device on the mar- ket. To learn how signals are routed from these inputs, see .

One Device: If you havejust one parallel effectsdevice, use AUX RETURN1 and leave AUX

RETURN 2 unplugged. That way, the unused AUX RETURN 2 LEVEL control can be used to feed AUX RETURN 1 to your stage monitors, via the EFX TO MONITOR switch .

Mono Device: If you have an effects device with a mono output (1 cord), plug that into AUX RETURN 1 LEFT and leave AUX RETURN 1 RIGHT unplugged. That way the signal will be sent to both sides, magically appearing in the center as a mono signal. This won’t work with AUX RETURN 2 — you’ll need a Y-cord to feed the L/R bus. In short, AUX RETURN 1 uses jack normalling. AUX RETURN 2 does not use jack normalling.
