30 ALT 3/4 OUT

33 BAL/UNBAL MAIN OUT – STEREO

INPUT

OUTPUT

POD

This is where the outputs appear from the channels that have been assigned via the MUTE/ALT switch. The post-EQ/post-fader/ post-panpot/pre-aux send signals from all of the muted channels appear at these outputs. Output is low impedance unbalanced and is designed to drive any input from low to high impedance. Maximum output level is +22dBu with a nominal operating level of +4dBu.

NOTE: Engaging a channel’s MUTE/ALT switch will deactivate its AUX sends. See the next section for several nifty ALT-3/4 OUT applications.

31AUX OUTPUTS

These are low impedance unbalanced outputs for the signals sent from AUX sends 1 through 6 (post-fader/post-EQ). Output is low impedance and is designed to drive ANY input from low to high impedance. Maximum output level is +22dBu with a nominal operating level of +4dBu.

32MONITOR OUT

This is a low impedance unbalanced output for the signals sent from the MON SEND (AUX1 pre fader/pre EQ). The output is designed to drive ANY input from low to high impedance. Maximum output level is +22dBu with a nominal operating level of +4dBu.

These outputs are electronically balanced (since they have both polarities available and are capable of driving +4dBu lines with 28dB of head- room). They’re also low impedance.

•For most music recording and PA applica- tions, unbalanced outputs are perfectly acceptable. Use standard cables. For cables runs over 50 feet, you may need a balanced line to reject noise.

•Balanced output is 6dB hotter than the unbalanced outputs.

•To use these outputs in balanced applica- tions, connect a stereo phone plug as follows:

Tip	= – (cold)			a	typo!
Ring	= + (hot)	This	is	NOT
Ring	= + (hot)
Sleeve = Ground
Sleeve = Ground

Why is the tip cold and the ring hot?! Well if you must know there are quite a few manufacturers that use this polarity configuration. No, you cannot go inside the CR-1604 and merely flip the wires around; doing so would short out your meters and void your warranty. If you absolutely must change the polarity try internally modifying a TRS adaptor or use an external phase reverser.

34MONO MAIN OUT

Same characteristics as the stereo MAIN OUTs except that the signal combines Right and Left Main Channels and the polarity is reversed (tip = hot, ring = cold).

NEED MORE OF A GOOD THING?

You can create a 32 or 48-channel mixer with the Mackie Designs MixerMixer combiner. It connects all the outputs of up to three mixers without losing channels via “cascading.” You can hook up two or three CR-1604s together, providing you with more of everything you love about our mixer as your budget and/or needs grow. The 1/LEFT and 2/RIGHT faders on each mixer become sub- mix faders. And we offer an optional 100mm Remote Fader to control the combined Main L/R outputs. Not satisfied with this stroke of flexibility, we’ve put together an ultra-affordable CordPack that includes all the cables necessary to interconnect three CR-1604s. This way, you won’t go broke buying 36 mono and three stereo cables piece- meal, which could add up to almost as much as the MixerMixer itself.

amp to this output in several cases.

Its output is HOT. First turn the PHONES fader all the way off. Then rotate the power amp’s level controls to 12 o’clock. Now bring up the PHONES fader gently.

If in the past you’ve had to put up with conven- tional, grungy-sounding headphone amps, you may initially be reluctant to “trust” the CR-1604’s headphone output. Not to worry. The sound quality is exactly the same as the main outputs and will not degrade your audio in any way.
