[. . . ] "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 level of this signal is represented by the LED meters. 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. However, don't be intimidated if you're using this mixer in your bedroom, which probably isn't equipped with a control room. In this scenario, you can use headphones or connect the CTRL RM OUT to your speakers. 12 A Tour of the MultiMix USB 2TK TO CTRL ROOM Switch When you engage this switch, the signal coming in from the 2TRACK jacks is routed to the headphones and to the control room output. This level is controlled by the HDPH / CTRL ROOM level control and cancels out any signal from the main mix. 2 AUX RETURN A LEVEL This is the level control for the signal returning to the mixer via AUX RETURN A. EFFECTS / AUX RET B LEVEL If you are using one of the MultiMix 8 USB's internal effects, this knob controls the effect level. If AUX SEND B is connected to an external device, this knob controls the level for AUX RETURN B. LED Meters These are the two rows of yellow, green and red lights you see in the master section of the mixer. The LED meters allow you to view the signal level of the main mix and 2-TRACK IN depending on which signal you have routed to the control room mix. POWER Indicator When this LED is lit up, that means the POWER ON switch on the rear of the mixer has been activated. +48V Indicator When this one is lit up, that means the PHANTOM ON switch on the rear of the mixer has been activated and is supplying +48V phantom power to all XLR mic inputs. 13 2 A Tour of the MultiMix USB Rear of the Mixer Here's what you'll find at the rear of the mixer. Power Input Here's where you plug in your mixer's external power supply. You should always connect your power supply to the mixer before you plug the power supply into an electrical outlet. The POWER INPUT is built to accept only the power supply unit provided with your MultiMix 8 USB, or an AC power supply that has the same specs. Others probably will not work. Power Supply Unit This unit provides 18. 5 VAC at 700 mA, more than enough to keep your MultiMix 8 USB running smoothly. As with nearly all power supply units, this one tends to get warm when left on for a while. This is perfectly normal. Power On Another easy one. Switch this one on and your mixer has power. Make sure that all master output knobs are turned all the way down when powering your mixer up or down. Phantom On This switch activates and deactivates the phantom power described in "Mic Inputs (Channels 1 ­ 4), " page 9. This switch controls phantom power for all four mic inputs. As we said earlier, it's very important that you plug in your microphones and mute your system before you turn on phantom power. USB port This port allows you to connect the Multimix to a computer for 2way, stereo digital audio communication. 14 3 Digital Effects Processor Onboard your MultiMix 8 USBTM is a powerful effects unit that has 100 preset programs. We offer a few tips on where to use these, but don't limit yourself to our suggestions. We recommend that you experiment with these effects to get a good feel for how they can improve your mixes. Effects Section Components Program Selection Knob You can use this knob to assign one of 100 effect programs to your mix.
