Aux Mix 1U

Intellijel

3-channel stereo mixer module with a stereo auxiliary (Aux) send bus. Designed for audio signals only (not CV). AC-coupled with audio-grade logarithmic attenuators. Channels 1 and 2 have Aux Level attenuators with Pre/Post switches. Rear panel has four 3-pin connectors for inter-module bus chaining.291

Capabilities 4

Auxiliary Send Busaux-send-bus
Channels 1 and 2 have Aux Level attenuators with individual Pre/Post fader routing switches, creating an independent aux mix routed to a separate AUX OUT pair. Soft-clipping diodes on the Aux output stage.291
Rear-Panel Bus Chainingbus-chaining
Four rear 3-pin connectors (Chain In, Chain Out, Aux Chain In, Aux Chain Out) allow direct connection to compatible Intellijel cases and modules without patch cables. Two 3-pin cables included. Multiple units can be chained for larger mixes.291
Soft Clippingsoft-clipping
Main and Aux output stages each have soft-clipping diodes for peak management.291
Stereo Mixerstereo-mixer
3-channel stereo mixer summing to main L/R outputs. Each channel has a Level attenuator, Mute switch, and activity LED. Left inputs normalled to right for mono sources.291

Jacks 10 — 6 in / 4 out

Inputs (6)
CHANNEL IN L1audioLeft input for stereo channel 1. Normalled to the right input so a mono source is duplicated to both sides.291
CHANNEL IN L2audio291
CHANNEL IN L3audio291
CHANNEL IN R1audioRight input for stereo channel 1. Normalled from left input when nothing is inserted.291
CHANNEL IN R2audio291

Outputs (4)
AUX OUT LaudioLeft output of the Aux mix bus, level set by AUX LEVEL controls on channels 1 and 2. Soft-clipping diodes prevent hard clipping. Overload LED indicator between the two jacks.291
AUX OUT RaudioRight output of the Aux mix bus. Soft-clipping diodes prevent hard clipping.291
MIX OUT LaudioLeft main mix output. Level set by LEVEL and MUTE controls on all three channels. Soft-clipping diodes prevent hard clipping. Overload LED indicator between the two jacks.291
MIX OUT RaudioRight main mix output. Level set by LEVEL and MUTE controls on all three channels. Soft-clipping diodes prevent hard clipping.291

Parameters 4

NameTypeRangeBehavior
AUX LEVELknobAttenuates the level of the channel's input signal routed to the Aux Mix. Available on channels 1 and 2 only. Behavior depends on PRE/POST switch setting.291
LEVELknobAttenuates the level of the channel's input signal routed to the Main Mix. Uses audio-grade logarithmic attenuators for smooth, even response.291
MUTEswitchSilences the channel at MIX OUT. For channels 1 and 2, if PRE/POST is set to POST, MUTE also silences the channel at AUX OUT.291
PRE / POSTswitchWhen set to PRE, AUX LEVEL is independent of LEVEL and MUTE. When set to POST, LEVEL determines the attenuation range of AUX LEVEL and MUTE will silence the signal to AUX OUT.291
