Page 7: Introduction
AMIX Series Automatic Mic/Line Mixer User Manual 1.0 Introduction This manual describes the components and operation of the Intelix AMIX Automatic Mic/line Mixer and the Intelix AMIX-LINK link module. A sophisticated auto-mixer, AMIX provides several modes of automatic mixing: last mic on, first-come, first-serve, and priority override. -
Page 8: Quick Start For The Amix Mixer
All AMIX mixers may be linked together serially (“daisy chained”) in one of two ways. The simplest and most flexible method is by using the Intelix AMIX-LINK module. If the application does not require the use of the AMIX-LINK (e.g., simple linking of two mixers), the mixers may be daisy chained using interconnect cables. -

This pot (RP2) controls the level to which the signal of an open mic is reduced when it is not active (not gated on). Reducing the signal rather than turning the mic off completely makes the gating off and on less obvious, resulting in a smoother sound. The amount of reduction intelix... -

LEDs should be lit on the temporary bargraph. 3.6 Priority Override Channel 8 (on AMIX-8) or channel 4 (on AMIX-4) becomes active while all other channels are muted. This mode is activated by an external switch connected to the DC control connec- tor on the rear of the mixer. -

Page 17: Gain Structure
In order to maintain the highest level of S/N in the mixer, the audio signals are never brought through the front panel controls of the Intelix mixer. Instead, each front panel pot controls a Voltage Controlled Attenuator (VCA), which controls the associated amplification stage. The channel VCAs do not control an amplifier, but are attenuation only devices which determine the amount of each channel’s contribution to the summing bus. -

5) Adjust individual channel volume knobs to the desired levels, as indicated on the bar graph (the bar graph monitors the output, but if one channel is adjusted at a time, the graph will reflect only that channel). intelix... -

4) Turn on the amplifier and set the mixer’s master volume to 6 or 7. Adjust the front panel volume control knob for each channel to the desired level (rather than using the clip LED as a guide because of its dual function as a signal detect LED). intelix... -

(clip) channel LEDs. The LEDs act as a temporary bargraph for the two pots: when the pots are full-on, the LEDs are all lit (AMIX-4 has four LEDs and AMIX-8 has eight LEDs). When the pots are full-off, none of the LEDs are lit. This bargraph function begins when the pots are rotated and lasts for a few seconds after the adjustment stops. -

Page 27: Passive Mixer Linking
There are two methods of linking AMIX mixers, passive or active linking. Passive linking uses only cables, whereas active linking uses the Intelix AMIX-LINK. Passive linking is suitable for linking two mixers, whereas active linking is easier and more flexible. Using the AMIX-LINK, up to six AMIX mixers can be linked into a single stack. -

10.0 AMIX-LINK Module This section describes the capabilities, operation and use of the AMIX-LINK Module. The Link Module is an accessory to the Intelix AMIX-4 and AMIX-8. The Link Module attaches to the rear of the AMIX mixer chassis, dramatically extending the capability of the AMIX mixer. -

Using the included audio cables (they have an RCA phono plug on both ends), connect the slaves “Link Out” port to the master’s “Link In” port. Note: There should be no connection to the master’s “Link Out” ports. The only connection to the slave’s “Link In” port should be the supplied shorting plug. intelix... -

Page 33: Connecting To The Reo Port
When remote control of all channels levels is required, the ReO port can be used to connect an Intelix mini-mixer to the AMIX mixer. This is accomplished by inserting an RCRJ11 adap- tor into the ReO port of the AMIX-LINK. Then the cable provided with the mini-mixer can be connected between the adapter and the mini-mixer. -

With proper connections to the Control Pin Port, the user can remotely control volume and muting of the following channels: 2, 4, 6, 8, and the master output. If it is necessary to have individual remote control over all channels, an Intelix mini-mixer connected through the ReO port should be used. -

Page 38: Using The Link In Port As A Balanced Link Input
This input goes directly to the summing bus and has no input volume control, thus input level control must be provided by the input device. The Link In Port is an ungrounded differential input. To correctly wire this input to the AMIX-LINK RCA port, follow the following direc- tions. intelix... -

If the hum is “in” the mixer, first check to see if the Ground Lift Jumper (J4) is present. It should be removed, unless the mixer is in a nonmetal cabinet.
