The S mix is a 5-channel compact mixer packed with high-end mixer features. The S mix features a balanced microphone input on an XLR connector and includes phantom power for connecting condenser microphones. Adding to the mix are two Super-Z, high impedance line inputs on 1/4" connectors. Rounding out the inputs is a stereo channel with two inputs on RCA connectors. Individual volume controls for the mic, lines and stereo channels are also included for enhanced control over the connected signals. And just because this unit is miniature, don't be surprised by its great sound and reliability thanks to high quality components and solid build construction.

Remove all packing materials (save them in case of need for future service) and check to make sure that you remove the supplied AC/DC power adapter. Note: Before plugging in and turning on, remember the "last on, first off" rule of power amplifiers and powered speakers. When powering up your system, be sure that all the wires are connected, turn your mixer and any other outboard gear on, and then last, turn your power amplifier or powered speakers on. When powering down, turn your power amplifier or powered speakers off first and then your mixer and outboard gear. · Connect the supplied AC/DC adapter to the DC Input on the rear panel of the S mix (Figure 1), then plug the adapter into any standard AC outlet. Set the S mix volume control knobs to the following default positions: All off. (Figure 2): Connect the S mix outputs to your power amp or powered speaker using the Left and Right RCA OUTPUT, or the 1/4" TRS jack OUTPUT connectors. Below is a wiring diagram for the 1/4" TRS stereo OUTPUT connector (Figure 3). Figure 2 Figure 1 · · Figure 3 5 Operating the S mix Connecting Inputs Signals to the S mix The S mix provides the capability of receiving signals from microphone, instrument and line level devices. Super-Z Line Inputs Channel 1 and 2 inputs are Super-Z, line/instrument level inputs on 1/4-inch phone connectors. The inputs can accept the signal from a variety of instruments level sources like those from the outputs of guitars, bass guitars and clavinets, and line level signals like those from the outputs MIDI keyboards, signal processors and drum machines, to name some. Mic input The channel 3 Mic input will accept signal from any low impedance microphone. You can use dynamic or condenser microphones since the S mix has phantom power present on the microphone input at all times. RCA Stereo Inputs Channels 4/5 are stereo line level inputs and are ideal for connecting a CD, Cassette or Mini Disk player. You can also run the signals from other line level devices such as keyboards or drum machines here. 6 Operating the S mix Typical Set-up The diagram below shows a typical set-up for a small band using the S mix miniature mixer. The vocalist's microphone is connected to the channel 3 mic input, a bass guitar is connected to channel 2 and channel 1 has a keyboard connected. For background tracks, a CD player is connected to the channel 4/5's stereo RCA inputs. SA N SO M 21 Rv Creating a Mix Now that you have connected your instruments and other sound sources to the S mix inputs you can begin to create your mix. The best way to do this is to adjust one channel at a time. Slowly raise the level control for the first input until you have reached the desired level. Now, repeat the same for each additional input. You may want to go back and slightly raise or lower an individual channel until you have set the balance between all the connected inputs. Then, you have your perfect mix! 7 S mix Specifications Frequency Response THD+N Noise Level Microphone Input Super-z Line Input Left and Right Inputs Left and Right Outputs Wiring Guide 10 Hz to 95 kHz <0,005 % -105 dBu XLR, balanced 1/4" jack unbalanced RCA, unbalanced input RCA, unbalanced output S mix Specifications - continued Mono, Instrument Level Output Input Impedance (Inst Chn.)
