PA800, PA1200, PA1200R MIXERS

OPERATING MANUAL

CONGRATULATIONS on your purchase of Carvin’s PA800, PA1200 or PA1200R Series mixer! The "R" version is a non-power rack model designed for your own power amp while the PA800 and PA1200 models included built-in high power amplifiers for direct hook-up to your speakers. Please read this manual carefully to take all the advantages of your new mixer.

SUPERB SOUND is derived from the extremely low distortion, high "Headroom" design. A state-of-the art, low noise, high headroom, balanced XLR preamp for each channel features a common mode rejection of better than 78 dB, which means that any possible noise that may come over your cables is virtually eliminated. Even the balanced XLR output connectors guard your system from cable noise for professional recordings or external power amp connections. Distortion is nearly non-existent with THD below .1%, which guarantees the purity of your sound. Hear the difference - your sound will not seem "sterile" or "processed". It will be dynamically open and transparent just like it was meant to be!

LIGHT WEIGHT and EASY TO USE everything is logically laid out making the PA Series simple to use, which helps to eliminate operator error. Its compact size and weight of 28 lbs. makes it the lightest, most powerful mixer of its kind. No other competitor in the industry offers a higher performance to weight ratio!

3 HIGH CURRENT AMPLIFIERS deliver 333 watts RMS each. A total of 666 watts is delivered to your main speakers (333 watts each for the R/L if played in stereo), plus a 333 watt amp to drive your stage monitors for a total of 1000 watts. This is the kind of output required for today’s professionals to maintain purity and integrity of sound. Six output jacks, two from each amp, deliver full power into 4 ohms, making these mixers more powerful than most amplifiers rated at 2 ohms. A peak indicator for every amp and a protect LED gives you a visual monitor.

A HIGH CURRENT POWER SUPPLY is provided by a beefy toroid transformer to assure continuous high amperage DC voltage to all three power amplifiers, eliminating "overload" or shutdown. 20,000 mfd capacitors offer a large power reservoir for bass thumping output.

The PA1200R features a 125k Hz switching power supply for operating your mixer at any voltage from 90 VAC to 240VAC. Like a laptop computer, you can go anywhere in the world and not worry about power adapters.

2 INDEPENDENT 24-Bit STEREO DSP EFFECTS allow you to assign each channel to your choice of effects. You can dedicate chorus/rev to the acoustic guitar channel and reverb to the vocals, etc. Both effects are adjustable to your stage monitors so you can hear yourself with full effects. The effects processors with 256 effects each, include reverbs, choruses, flanging and echoes, with parameters fully adjustable for; damping, decay, depth, speed, regeneration and time.

ACTIVE 3 BAND CHANNEL EQ provides easy adjustment for the tone you want. The LO frequency controls starts at 20 Hz and continues through 80 Hz for a solid non-flabby bass. A simple adjustment with the MID band, gives you the best sound for vocals or guitar in the very important 750Hz frequency range. The 11.5k Hz HI treble control adds sparkle to your top-end without adding harshness. Both the LO and HI are "shelving", which means they are effective from 20Hz up to 20k Hz.

TWO 9 BAND EQUALIZERS provide precise 1 octave adjustments to fine tune your over all sound and to help control feedback. Unlike one stereo graphic equalizer, two independent 9 bands give you total flexibility. At the push of a button, you can assign both equalizers to the main and monitor speakers or to the L and R outputs.

ENGINEERED TO LAST Every PA Series mixer incorporates a rugged reinforced steel chassis. Continuous full power is assured from a 370 sq inch, high-grade 6063-T5-aluminum heat sink cooled by a quiet dual-speed fan. You’ll never have to worry about protect or power reduction modes.

ENGINEERED TO LAST cont. Hidden deep in the heart of these mixers is the “SMT” Surface Mount Technology construction that utilizes surface mounted components to prevent parts from shaking or vibrating loose. Sealed controls and switches guard against the outside elements while heavy-duty connectors provide a positive connection to your cables. Fire retardant FR-4 military spec circuit cards feature double-sided copper construction to guard against noise and radio frequencies (RF). Precision 1% tolerances guarantee that your settings will be accurate every time. The multi-ply wood cabinet is not the typical heavy particleboard that can break or crack, and the Duratuff covering is scratch and dent resistant. The PA Series is professionally made in the USA for years of service!
