Rane MX 23 Operator's Manual

Manual-1

QUICK START

Whoa, hold on there. Even if you don’t read manuals as a matter of principle, at least read this section to avoid hurting

yourself or your equipment.

Connect the MX 23 with the POWER off. Balanced XLR cables are recommended, but if you must convert to ¼"

connectors, buy or make a cable like the ones on page Manual-11 and keep them as short as possible. This device uses low

impedance balanced line drivers. Do not connect the “+” or “–” output pins to ground, as this may cause the power supply

to shut down. For unbalanced use, leave the unused output pin (“+” or “–”) unterminated.

Consult the speaker manufacturers for the correct crossover FREQUENCY settings. As rugged as some drivers are,

many (especially compression drivers) will not accept frequencies outside of their normal range without producing distor-

tion and possibly self-destruction.

With all equipment turned off and LEVEL controls down, begin making connections to the system as shown on page

Manual-4 or 5. When turning on the system, switch on the power amplifiers last. Now, feed the MX 23 some program

material. Start by turning up the LOW LEVEL, MID LEVEL and HIGH LEVEL to the 0 dB marks. Slowly increase the

INPUT LEVEL, even if it goes all the way to 10, so the +4 dBu (green) light blinks occasionally and the OL (red) light

stays out. This delivers the best signal-to-noise performance.

The MONO SUB OUTPUT is a sum of the Left and Right Low Outputs. The MONO SUB LEVEL adjusts only this

Output and is not affected by the LOW LEVEL control.. When using a single mono bass bin along with stereo mid- and

high-range cabinets, set the 100 Hz FILTER to OUT, allowing the front panel FREQUENCY to control the subwoofer

crossover point. When used with 3-way cabinets and a subwoofer, set the 100 Hz FILTER switch to IN to allow only

frequencies below 100 Hz at this output jack. This way, the MX 23 almost does the job of a Stereo 4-Way crossover, but

without removing that awesome bass from the Left and Right Low Outputs.
