Introduction
Your new AP812/818 Mixer/Amplifier is designed and built to provide long-term trouble free performance. Drawing on over thirty years of experience in the design and manufac- ture of powered mixing consoles, Yorkville engineers were able to optimize the design of the AP812/818. Including comprehensive features such as rack-mountability, quiet internal fan cooling, two stereo input-channelswith cue buttons, headphone monitoring (of both the cue and monitor busses), phantom powering, dual 9-band EQ’s, power amp channels and EQ’s assignable to Left/Right stereo operation or Main/Monitor mono opera- tion, 255-preset digital signal processing, dual level-meters, 800 watts of stereo power built-in, both 1/4-inch phone plugs and Speakon® output connectors.
Terminology
•3-pin microphone inputs are referred to as XLR connectors.
•1/4-inch jack sockets are called phone connectors.
•Balanced 1/4-inch inputs or outputs are called TRS or Tip-Ring-Sleeve
•Master control and mixing channels are called busses.
•Overload indicators are called Clip LED’s.
•Patch cables with dual conductors plus shielding and ring-tip-sleeve (stereo) 1/4- inch phone plugs are referred to as balanced patch cables.
Basic Features
Channels 1 - 8 (1 - 14)
•XLR MIC and balanced TRS LINE inputs with low-noiseinput circuit design.
•Balanced LINE inputs accept either balanced or unbalanced lines.
•PHANTOM power (24 volts).
•Extremely wide input GAIN-adjustment.
•MONitor send controls are post-EQ and pre-fader.
•Three-band EQ with +/-15 dB of range and a sweepable mid (80 Hz - 8 kHz).
•Post-EQ, post-fader, EFX (effects) send controls.
•PAN controls provide constant gain levels at all settings.
•Increased circuit headroom and gain for a more flexible mix.
•Gold internal bus-interconnectsfor long life and maximum signal integrity.
•CLIP LED’s indicate even the briefest peaks, and fire at -3 dB, well before the onset of actual clipping, at any and all active channel stages.
Stereo Channels (9/10, 11/12, 15/16 & 17/18) (see diagram on following page)
•Left and Right 1/4-inch balanced TRS LINE inputs accept either balanced or Unbalanced lines.
•The LEFT TRS input may be used for connecting a mono source and will inter- nally patch it to the RIGHT channel input circuitry.
•LEFT and RIGHT RCA inputs.
•LOW, MID and HIGH frequency shelving EQ (+/- 15 dB).
•BALANCE control
•CUE buttons let you preview these channels through headphones with the level faders shut off.
