CONTROLS AND CONNECTIONS
1.Channel Volumes control input signals over a range of 60dBm attenuation at full off to 20dBm of gain at full on.
2.Pan Pots (Mix 5 Stereo only) are dual pots with center detent, providing over 65dB of stereo isolation from left to right channel. The center deten t allows convenient and accurate setup, feeding signal equally to both channels.
3.Aux Input Pot controls the rear panel RCA input jacks. Input signals are actively summed in the Mix 5 Mono, and maintain stereo separation in the Mix 5 Stereo. Again, with a range of
4.Master Volume Pots (one for Mix 5 Mono) determine the amount of signal from the summing amps that is fed to the output drivers and the meters. These also have a gain range of
5.LED dB Indicators are precisely calibrated in 3dB increments and span a range of
6.Phantom Power for each of the four input XLR jacks is activated by the rear panel pushbutton switch. Status is indicated by the front panel LED. Each channel is individually filtered to eliminate crosstalk through the supply rail. The Mix 5 supplies l8VDC with current limiting resistors chosen to ensure that the phantom supply will not fall below the AES minimum specification of l2VDC at a 5.2mA current draw. Most condenser type microphones draw between 1 and 3mA and will operate from 12 to 48VDC.
7.Power Switch connects AC to the transformer primary and the LED indicates that the unit is receiving power. Both sides of the AC line are switched and a mains fuse is located on the circuit board inside the unit.
8.Input 1/4” TRS and XLR Jacks are
common, wired to sleeve. Audio ground is not connected to chassis ground.
9.Input Mic/Li ne Switch is engages an active circuit t hat applies 20dB of gain when in the Mic position. This gain is applied to both input jacks. For most input signals the Out or Line position will be appropriate.
10.Output Male XLR Jack (left for stereo) is balanced with pin 2 positive, pin 3 negative and pin 1 audio ground. For unbalanced operation use pins 1 and 2 leaving pin 3 UNCONNECTED. To internally lift pin 1 from common, open the unit and cut jumper JMP84.
11.Output Mic/ Line Switches affect only the XLR output jack(s) by inserting a 20dB pad across pins 2 and 3 when in the Mic position.
12.Output 1/4” TRS Jack delivers the same signal as the XLR but has a separate driver circuit providing complete isolation from the XLR output. May be used either balanced with a TRS plug or unbalanced with a TS plug. Tip is positive, ring is negative and sleeve is audio ground. This jack can drive high impedance headphones directly, although one side is out of phase. A properly wired adapter cable can provide monitoring capabilities.
13.Output 1/4” TRS Jack is connected to the right output and is identical to #12 above for the Mix 5 Stereo. It provides a second active isolated TRS output in the Mix 5 Mono.
14.Output Male XLR Jack and Mic/Line Switch appear only on the Mix 5 Stereo and operate identically to #10 and #11 above, providing the right channel output. To internally lift pin 1 from common, open the unit and cut jumper JMP85.
15.Power Cord has a standard 15 amp plug for l20VAC and has no plug on the Mix 5MX or Mix 5sX 230VAC export models. Black is line, white is neutral and green is earth.
