[. . . ] However, if you engage the 2TK TO CTRL ROOM switch, the CTRL RM OUT will carry the signal present at the 2-TRACK inputs. 10 A Tour of the MultiMix USB 2 Channel Strips The eight channel strips are virtually identical to each other, with the only difference being that channels 1 ­ 4 are mono and channels 5 ­ 8 are stereo. Each channel strip contains the following components. Level Control The level control knob controls how much of the signal from the mic or line inputs is sent to the channel. In the leftmost position, levels are cut completely, and in the rightmost position you get an additional 10dB of gain. PAN or BAL This control--labeled PAN on the mono channels and BAL on the stereo channels--lets you assign the channel to a particular spot within the stereo spectrum. If you turn this knob to the left, you can hear the signal move to the left, and if you turn it to the right. . . you get the picture. The pan controls do this by adjusting the amount of the signal being sent to the left main mix bus versus the right main mix bus. The balance controls do it by controlling the relative balance of the left and right channel signals being sent to the left and right main mix buses. PEAK LED This indicator lets you know when the channel's signal is clipping. This light plays an important role in setting channel levels by helping you know when to reduce the channel's gain. Aux Here you'll find knobs that control the levels of aux sends A and B. AUX A is pre-fader, which means that the AUX A send is affected only by the EQ and HPF settings. A pre-fader send is usually used for cue sends (for example, sending a signal to headphones while recording, for which you may not want the fader to alter the channel's level). AUX B is post-fader, which means that the AUX B send is affected by the fader (or level control knob in this instance), EQ and HPF settings. A post-fader send is generally used for sending the signal to an external effects device (so that the fader controls the signal level). Like AUX A, AUX B can be used for routing signals to external devices. And when you are using the onboard effects processor, AUX B is used to control the level of the channel's signal being routed to the processor. 11 2 A Tour of the MultiMix USB EQ The MultiMix gives you three bands of EQ per channel. Using these knobs, you can tailor the channel's signal by boosting some frequencies and cutting others. The LO and HI controls are shelving controls with fixed frequencies of 75 Hz and 12 kHz respectively. "Shelving" means that the mixer boosts or cuts all frequencies past the specified frequency. "Peaking" means that frequencies above and below the specified frequency fall off, forming a peak in a graphical representation. Master Section The Master Section is the heart of the mixer, where the channel inputs and aux returns all are mixed together and routed in various ways. Main Mix The signals from all channels and aux sends are sent to the main mix. The MAIN MIX level control is the one you'll use to control the overall level of those combined signals. This knob affects the levels of the signals sent to the MAIN MIX OUT and the 2TRACK OUT. In its leftmost position the signal is cut off completely, and in the rightmost position you get an additional 10dB of gain. 2TK To Mix When you press this switch, the signal coming in through the 2TRACK IN gets routed to the MAIN MIX, joining whichever other signals are already part of the main mix. Used this way, the 2-TRACK IN effectively becomes another stereo channel (but without all the extras like pan, EQ, etc. ). HDPH / CTRL RM The HDPH / CTRL RM knob controls the level of the signal being sent to the CTRL RM OUT and the PHONES output. The "CTRL RM" in the name of this knob refers to the fact that it controls the signal that typically is sent to the control room monitors of a studio, where someone--usually an engineer--is working the mixer. [. . . ] A line output whose function is to send a signal from the mixer to an external device, usually an effects processor. Refers to the setting of an audio channel at which the signal leaves the channel at the same level at which it entered. The opposite of "dry.
