Owner's Manual Output Section 37 38 36 39 35 30 33 31 34 now, you probably know what the main mix is. Alt 3-4 is that additional stereo mix bus. Tape is the stereo signal coming in from the tape input [13] jacks. Selections made in the source matrix deliver stereo signals to the control room, phones and meter display. With no switches engaged, there will be no signal at these outputs and no meter indication. The exception is the solo function. Regardless of the source selection, engaging a channel's solo [22] switch will replace that selection with the solo signal, also sent to the control room, phones and meters. This is what makes the getting started p rocedure so easy to do. Warning: Engaging both the tape and assign to main mix [33] b utton can create a feedback path between tape input [13] and tape output [14]. Make sure your tape deck is not in record, record-pause, or input-monitor mode when you engage these switches, or make sure the control room / submix [32] level knob is fully counterclockwise (off). Now you know how to select the signals to send to the engineer's control room or phones. 32 29 29. Main Mix This knob controls the levels of signals sent to the main outputs: XLR [17] and 1⁄4" [16] and RCA tape output [14]. All channels and stereo returns [8] that are not muted or turned fully down will wind up in the main mix. Fully counterclockwise is off, the center is unity gain, and fully clockwise provides 12 dB o f additional gain. This additional gain will typically never be needed, but once again, it's nice to know it's there. This is the knob to turn down at the end of the song when you want "The Great Fade-Out." 30. Control Room Source Matrix Typically, the engineer sends the main mix to an audience (if live) or a mixdown deck (if recording). But what if the engineer in the control room needs to hear something other than the main mix? With the 802VLZ4, the engineer has several choices of what to listen to. This is one of those tricky parts, so brace yourself. With these source switches, you can choose to listen to any combination of main mix, alt 3-4 and tape. By 31. Phones This knob controls the level going to your stereo headphones. Make sure this is fully down whenever you are making connections in your system, or putting on the headphones. Bring up the level slowly and carefully to protect your hearing. This dedicated phones level knob makes it is easy to turn down the studio monitors and listen just with the headphones, when overdubbing, or when in a room full of sleeping and hungry leopards. 32. Control Room/Submix This knob controls the level of the stereo control room outputs [10]. The control range is from off through unity gain at the center, with 10 dB of extra gain when turned fully clockwise. When main mix is your control room source selection, those signals will now pass through three level controls on the way to your control room amp and phones : the main mix [29] knob, this control room / submix knob, and the phones knob [31]. This way, you can send a nice healthy level to the main output (main mix knob at "U"), and a quiet level to the control room or phones (control room / submix knob and phones knob where you like). When alt 3-4 or tape is selected, or a channel solo [22] is engaged, the control room / submix knob and phones knob will be the only ones controlling these levels (channel controls not withstanding).
