[. . . ] MX802A Users Manual Version 1. 1 January 2001 EURORACK ® www. behringer. com ENGLISH EURORACK MX802A FOREWORD Dear Customer, Welcome to the team of EURORACK users and thank you very much for expressing your confidence in BEHRINGER products by purchasing this unit. It is one of my most pleasant tasks to write this letter to you, because it is the culmination of many months of hard work delivered by our engineering team to reach a very ambitious goal: To produce a compact mixer, which fully satisfies your and our expectations and delivers a superior sound quality, easy operation and technical specifications. In addition to that the mixer is affordable for almost every musician. The task to design the EURORACK MX1604A certainly meant a great deal of responsibility, which we assumed by focusing on you, the discerning user and musician. [. . . ] Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage, which may have occurred in transit. + If the unit is damaged, please do not return it to us, but notify your dealer and the shipping company immediately, otherwise claims for damage or replacement may not be granted. MONO INPUT CHANNEL Each mono channel comes with an XLR mic input and a balanced line input on 1/4" jack . The gain circuit has a wide range from +10 dB to +60 dB, obviating the need for mic/line switching. The crucial operating input levels +4 dBu and -10 dBV are clearly and accurately marked . 2. 1 Input level setting Mic channel input level is determined by the GAIN control . In addition to main mix metering, a channel PEAK LED illuminates when a channel is going into overload. This level sampling is particularly useful when using extreme EQ settings. To accurately set input follow the procedures given in section 5: SETTING UP. However, if the PEAK LED does not light the input gain cannot be too high. If a reasonable input level is selected, auditioning a single signal should result in a reading of around 0 dB on the main mix meters , provided that both channel and output level controls are set to unity gain (0 dB). 2. 2 Equalizer All mono input channels are fitted with three-band EQ, plus a switchable low cut filter for eliminating unwanted subsonics. The upper and lower shelving controls have their frequencies fixed at 12 kHz and 80 Hz respectively. The Mid Range control has a peaking response, with Q fixed at 2 octaves, frequency at 2. 5 kHz. All three bands have up to 15 dB of cut and boost, with a centre detent for off. The low cut filter , slope at 18 dB/oct. , -3 dB at 75 Hz, is ideally suited for reducing floor rumble, breathing noises and popping, woolly bottom end etc. + The combination of shelf boost at 80 Hz together with low cut at 75 Hz results in a peaking response, useful for adding warmth to vocals and instruments, and a firm bottom to kick drums and basses, without losing control of low frequency speaker cones. 2. 3 Aux sends Both aux sends are mono and post-EQ. For almost all FX send purposes, you will want aux sends to be post-fader, so that when a fader level is adjusted, any reverb send from that channel follows the fader. Otherwise, when the fader is pulled down, the reverb from that channel would still be audible. MONO INPUT CHANNEL 7 EURORACK MX802A 4. 2 Stereo aux returns There are two additional stereo line inputs (aux returns 1 and 2) on your MX802A. If you connect a jack only to the left socket, the aux return 1 operates in mono. Aux return 2 can be switched between the main mix and the cue feed (aux send 1) via a switch marked FX TO AUX 1 . If no connection is made to aux return 2, the signal is normalled (connected directly) to aux return 1. Depressing FX TO AUX 1 will then feed the signal from aux return 1 into the cue feed (aux send 1) and can be controlled in level independently with aux return 2. This feature is primarily useful when you are using one effect for the main mix and for the foldback speakers. + + When using aux send 1 as a second (pre-fader) effects send and aux return 2 as the effect input, do not engage FX TO AUX 1 . Sometimes an engineer wants to narrow the stereo width of a reverb field.
