OPERATORS MANUAL MX 23 STEREO 3-WAY CROSSOVER 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 ј" 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 distortion 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. WEAR PARTS: This product contains no wear parts. Manual-1 INPUT LEVEL control and indicators This controls the overall level without altering the relative settings of the Low, Mid and High frequency Outputs. Input gain is +6 dB at "10". With signal applied, set this control so the +4 dBu LED lights occasionally, indicating sufficient signal. Flashing of the OL (overload) LED during peaks can be avoided by turning the INPUT LEVEL down. LOW LEVEL control This controls the level of signal going to the LOW OUTPUT jacks. Unity gain is reached at the "0 dB" mark with the INPUT LEVEL set to "10". This control does not affect the MONO SUB OUTPUT level. Refer to Operating Instructions on page Manual-6. LOW/MID FREQUENCY control This 31-position selector sets the crossover frequency between the Low and MId frequency Outputs in both Channels. Consult the manufacturer of the drivers or cabinets for the correct setting. Cable Wiring
