[. . . ] The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus. Only use attachments/accessories specified by the manufacturer. [. . . ] wARNING: Pre-fader SOLO taps the channel . Signal before the fader If you have a channel’s fader set well below “U” (unity gain), SOLO won’t know that and will send a unity gain signal to the PHONES output. That may result in a startling level boost in your headphones. ASSIGN Used in conjunction with the PAN knob, ASSIGN determines the final destination of a channel’s signal. Engaging ASSIGN 1-2, for instance, sends that channel’s signal to the SUB 1 and 2 Faders and, via their SUB ASSIGN switches, the MAIN MIX Fader . typically , ASSIGN 1-2 will be engaged on all channels destined for the main mix. By configuring SUB 1 and 2 to feed the main mix, the channel ASSIGN 1-2 switches become the equivalent of being “Main Mix” switches. Some channels can use ASSIGN 3-4 instead; creating a submix for a set of channels (all the drum channels, for instance). Then, by configuring SUB 3 and 4 to also feed the main mix, you can “ride” the SUB 3 and 4 Faders independently of the rest of the mix. sUB Faders , SUB ASSIGN , and MAIN MIX Fader will explain this further. -15 +15 PAN L R 1 1 dB 10 5 MUTE ASSIGN 1-2 3-4 U 5 10 20 30 40 50 60 O O SOLO PFL FADER Although the most self-explanatory item on a mixer, we’ll explain it anyway: The fader is the master level control for the channel’s sig14 MASTER SECTION FEATURES We hope you’ve understood, if not memorized, the CHANNEL STRIP FEATURES you just read.

Tening to via the PHONES You can get a good mix with the meter’s peaks flashing anywhere between –20 and +10 dB. Most amplifiers clip at about +10 dB, and some recorders aren’t so forgiving either. For best real-world results, try to keep your peaks between “0” and “+7. € You may already be familiar with “+4” (+4 dBu=1. Basically, what determines the operating level is the relative 0 dB VU (or 0VU) chosen for the meters.
