40. TAPE IN (LEVEL)

This knob controls the level of the stereo signal coming from the TAPE [12] INPUT RCA jacks. Its range is off when fully down, unity at the center detent, with 20 dB additional gain turned fully up, which may come in handy if you’ve patched in a device with wimpy output levels. After the TAPE IN level is determined, the stereo tape signal can be sent to either of two places — the main mix or the SOURCE [42] matrix.

42. CONTROL ROOM SOURCE

Typically, the engineer sends the main mix to a live audience or to a mixdown deck (if recording). But what if the engineer needs to hear something other than the main mix? With the 1642-VLZ3, the engineer has several choices of what to listen to.

Via these switches, you can choose to listen to any combination of MAIN MIX, SUBS 1-2, SUBS 3-4 and TAPE. Selections made here deliver stereo signals to the control room, headphones, and meter display. These signals are tapped off as follows — post-MAIN MIX [37] fader, post SUBGROUP [38] faders, and post-TAPE IN

[40]knob. With no switches engaged, there will be no signal at these outputs and no meter indication, with two exceptions: SOLO and STEREO RETURN 4.

Regardless of the SOURCE selection, engaging a SOLO

[27]switch will replace that selection with the SOLO signal, also sent to the control room, headphones, and meters. This is what makes the Level-Setting Procedure so easy to do.

Now you know how to select the signals you want to send to the engineer’s control room and/or phones. From there, these signals all pass through two level controls:

43. CONTROL ROOM AND PHONES

These knobs control the level of the stereo C-R OUTS [9] and PHONES [10] outputs.

You can use the control room outputs for other ap- plications, such as an additional main mix output with its own level control. However, should you do this, be aware that if you engage a SOLO switch, it will interrupt the mix:

Once again, engaging a SOLO [27] switch will cause this dramatic turn of events: Any existing SOURCE [42] matrix selections will be replaced by the SOLO signals, appearing in the control room, headphones, and meters. The audible solo levels are controlled by the SOLO [46] level knob. The SOLO levels appearing on the meter display are not controlled by anything — you wouldn’t want that. You want to see the actual channel level on the meter display, regardless of how loud you’re listen- ing.

41. TAPE TO MAIN MIX

Engaging this switch is just like engaging the L/R switch on a channel — the signal, stereo in this case, is sent to the main mix. It does not interrupt other signals, just adds itself to them. This switch can be very handy in a live sound situation when you want to play soothing elevator music to an anxious crowd.
