- Remove all packing materials and decide where the unit is to be physically placed. The SM4 can be mounted in any standard 19” rack (requiring one rack space), or used on a tabletop.
- Before connecting a microphone or line level audio device, make sure that the power to all your systems components, including the SM4, are turned off.
- Using an XLR or 1/4” cable, connect a wired microphone or the output of a wire- less microphone receiver to the Mic input jack on the rear of the SM4.
- Connect a music source, like a CD player, to the RCA jacks on the rear panel of the SM4. The red connector is the right input and the white connector is the left input. Portable audio devices, like an MP3 player, can be connected to the 1/4” or 1/8” stereo inputs on the front of the SM4.
- Connect the outputs of the SM4 to the inputs of a power amplifier or speaker system using XLR or RCA cables.
- Turn the SM4 Master Volume control all the way down and turn the SM4 power on.
NOTE: It is important to remember the Golden Rule of audio ... “LAST ON, FIRST OFF”. Translated, this means that when turning on your system, you should always turn your power amplifiers or powered monitors on LAST, and when turning your system off, turn your power amps off FIRST. This helps avoid any loud pops caused by rush current at power up, which can sometimes damage loudspeakers.
- Turn the power amplifier or speaker system on and turn the volume up.
- Set the MIC volume control of the SM4 to the 12 o’clock position.
- While talking into the microphone, raise the MASTER VOLUME control until you have reached the desired level.
- Play music from the connected music source and raise the MUSIC volume control. Adjust the MIC and MUSIC volume until the microphone signal is able to be heard above the music.
