ONYX 4•Bus

83. MAIN INSERTS

These 1/4" TRS jacks are for connecting serial effects such as compressors, equalizers, deessers, or filters. The insert point is after the mix amps and BREAK [61] switch, but before the MAIN MIX faders and the built-in compressor. Refer to the description of the channel insert on the previous page to see how to make this connection.

84. MONO OUT

This male XLR output connector provides a balanced line-level signal that is a combination of the left and right MAIN OUT signals (L+R). You can use this for a separate mix that doesn’t require a stereo feed, or to simply test the monaural compatibility of your stereo mix.

85. GROUP OUTS 1-4

These 1/4" TRS output connectors provide balanced or unbalanced line-level signals for connecting to the inputs of any line-level device.

86. GROUP SEND INSERTS

These 1/4" TRS jacks are for connecting serial effects such as compressors, equalizers, deessers, or filters. The insert point is after the mix amps, but before the Group Send Masters (and before the built-in stereo compres- sor). Refer to the description of the channel insert on the previous page to see how to make this connection.

87. AUX SENDS 1-6

These 1/4" TRS output connectors provide balanced or unbalanced line-level signals for connecting to the inputs of effects devices or stage monitor amplifiers.

88. AUX SEND INSERTS

These 1/4" TRS jacks are for connecting serial effects such as compressors, equalizers, deessers, or filters. The insert point is after the mix amps, but before the Aux Send Masters and the AFL Solo switch (so you can hear the external processor when soloing the aux send). Refer to the description of the channel insert on page 22 to see how to make this connection.

89. Power Receptacle

This is a standard 3-prong IEC power connector. Connect the detachable linecord (included in the box with your Onyx 4•Bus) to the power receptacle, and plug the other end of the linecord into an AC outlet. The Onyx 4•Bus has a universal power supply that can accept any AC voltage ranging from 100 VAC to 240 VAC. No need for voltage select switches. It will work virtually anywhere in the world. That’s why we call it a “Planet- Earth” power supply! This also means that it is less susceptible to voltage sags or spikes, providing greater electromagnetic isolation and better protection against AC line noise.

90. POWER Switch

This one is self-explanatory. When the POWER switch is turned ON, power is supplied to the Onyx 4•Bus and the POWER LED on the front panel lights up.

Press the bottom of this switch to put the mixer into

standby mode. It will not function, but the circuits are still live. To remove AC power, either turn off the AC mains sup- ply, or unplug the power cord from the mixer and the AC mains supply.
