[. . . ] CARVIN ENGINEERING DATA RX800, RX1200, RX1200R MIXERS OPERATING MANUAL DISTORTION-FREE LIMITERS The purpose of a limiter is to hold down peaks so the amp won't distort even with extra hot input signals (this protects your expensive speakers). In addition, limiters can increase your amp's average output by 3 db or more. Part of Carvin's design uses the more expensive, distortion-free linear "opto isolators". Unlike amps that use FET controlled limiters which can inject small amounts of distortion, our limiters keep your sound pure and uncolored! [. . . ] When used in such an environment, be sure the mixer is adequately protected by a cover.

PETERSEN 14JUN05 RX800, RX1200, RX1200R CONTROLS QUICK START UP If you're like most new owners, you're probably in a hurry to plug your mixer in and use it. Here are some brief instructions to get you going quickly. With the mixer unplugged and the unit turned off, complete the following procedures: A. CONNECTING AC POWER TO YOUR MIXER · Be sure to plug your mixer into the proper voltage for your country, either 120V-60Hz or 240V-50Hz. The RX1200R accepts both voltages listed. · Use only a grounded (3 prong) power outlet to prevent a shock hazard. This gives the quietest grounding for your mixer. CONNECTING INPUTS TO YOUR MIXER · For balanced microphones, use a shielded cable and plug into the XLR MIC inputs. The LO and HI controls are shelving type with corner frequencies at 80Hz and 11. 5k Hz respectively. The MID control is a band pass type centered at 750Hz. 14. LEFT & RIGHT XLR OUTPUTS The LEFT and RIGHT balanced XLR line outputs are the same signals that feed the internal AMPS 1&2. Use these outputs for additional power amps or recording gear. 15. MONITOR 1& 2 OUTPUTS The MONITOR 1 - 2 line outputs are the same signals that feed the internal MONITOR AMPS 3 & 4. Use these outputs for additional power amps or recording gear. 9 MIC CHANNEL FEATURES 1. LINE INPUT/INSERT JACK The LINE input is a 1/4" phone jack designed for balanced or unbalanced line or instruments. Examples of these inputs would be guitar, keyboard or CD player. The line input can be used at the same time the mic input is being used. This jack becomes an insert when the INSERT switch is pushed "IN". 8 7 2. INSERT SWITCH This switch changes the function of the channel's 1/4" jack. [. . . ] The builtin power amp limiters are post insert. Patching a compressor or equalizer between the mixer and the amp can be done by using a stereo insert cable (like Carvin's AP1). Connect the RING signal to the INPUT of the external device, and the TIP signal from the OUTPUT of the device. Plugging in a standard 1/4" cable (mono) into the AMP PATCH INSERT jacks allows any external signal to be sent to the internal power amps. [. . . ]
