Yorkville Sound AP812, AP818 owner manual Channel Faders, Clip LED, EQ/Amp Assign Button

Channel Faders

This adjusts the levels of both the post-EQchannel signal headed directly for the LEFT and RIGHT MAIN master bus (via the PAN/BAL pot), and the EFX send signal headed for the master EFX bus. The channel fader does not control the MONitor send level.

Clip LED

The channel CLIP LED watches all the active electronic stages in the channel circuit. Whenever any stage’s signal peak approaches clipping to within 6 dB, the CLIP LED circuitry captures and displays this event. See under GAIN control for more about this feature.

Monitor Master & Clip LED

This control regulates the overall level of the master MONitor bus. The CLIP LED, like the others, fires at 6 dB below the onset of actual clipping so that a small amount of activity is quite acceptable. If the LED flashes frequent- ly, reduce the MON MASTER setting, or possibly one or more of the channel MON send settings. The output of the MON MASTER bus goes to the MON OUT jack. It also goes to the EQ/AMP ASSIGN button where it can be directed to the EQ2 equalizer and then to the RIGHT- channel of the built-instereo power amplifier. Regardless of the EQ/AMP ASSIGN button’s operation, the MONitor signal remains available at the MON OUT jack so that it can be used to drive an additional amp/speaker system.

Mon Out Jack

Located in the upper right area beside the PHONES jack, MON OUT is the output of the monitor bus. It is at line level (do not connect speakers to it directly) and unbalanced. Connect your monitor power amp or powered monitors here.

User tip: If another monitor system is in use, perhaps full-range enclosures running off the main PA mix as side-fills, you could connect a tape deck here

to record live performances. Plug a single 1/4-inch male-to-dual 1/4-inch female Y adapter into the MON OUT jack. Now simply run two of the appro- priate patch cables (probably 1/4-inch male-to-RCA male) into the tape deck’s L & R line level inputs. You will now have the advantage of being able to mix for recording, independent of the PA mix.

Left & Right Main Masters

EQ/Amp Assign Button

The MAIN master faders receive signals from the chan- nel PAN/BAL controls and determine the output signal levels at the L & R PRE-EQ LINE OUTPUT jacks.

User tip: Regardless of the ASSIGN button’s func- tion, the PRE-EQ LINE OUTPUT jacks will always carry the unequalized L & R stereo mix. This can be useful if you are recording the live performance.

The MAIN faders also determine the signal levels destined for the EQ/AMP ASSIGN button where they are directed as follows:
