Functions and Control
- Input Jack –This is a balanced XLR microphone input jack. This XLR input jack is fixed to a microphone through a flat microphone cable with a male XLR plug.
- Input Jack – This is an unbalanced 1/4″ input jack. The input jack is connected to a microphone, a musical instrument, or an audio device through an unstable part with a 1/4″ TS plug.
- Jack – This is a 1/4″ TRS phone jack allowing you to insert external line devices into the signal path. This insert jack is connected with the “TIP” send and “RING” return.
- Control Knob – This knob is used to raise or lower the gain height of the input signal. When the audio size is higher than a predetermined threshold, the LED indicator will keep flaming until the audio sizes go below the threshold.
- Control – This control determines how much of the input signal is sent to the left and right channels. When the knob is centred at noon, the input signal is sent equally to the left 4 channel mixer and the right track with an attenuation. Turn this control fully counter-clockwise to ship 99% of the input signal to the left channel. Turn this control fully clockwise to send 99% of the input signal to the right track.
- Treble-tone Control Knob – This knob is used to adjust the gain for the input signal band centred at 12.5KHz in the range from -15dB to +15dB.
Precaution
On Safety
- Operate only on the designated AC power supply.
- Should any liquid or hard solid object fall into the equipment, unplug the unit and have it checked by trained personnel before operating it to the next step.
- Unplug the unit from the wall or set the Master switch OFF if it is not used for some coming days.
- To disconnect the stand, pull it out by the plug. Never pull the cable itself.
when doing Installation
- Enable adequate air circulation to prevent internal heat build-up. Do not place the unit on surfaces or near materials that may block the ventilation area.
- Do not install the unit in an open location near heat sources such as radiators or air ducts or a place subject to direct sunlight, excessive dust, shock or mechanical vibration.
When Repackaging
Do not put away the carton and packing equipment. They make a perfect container in which to transport the system. When moving the unit to another location, repack it as it was originally packed at the factory.
Sound Mixer Channels
Each input source connects to the mixer through a channel. The more media a system has, the more seeds it can accept. The following examples show some common ways to describe a mixer’s complement of 4 channel mixers. On most sound desks, input channels take up most of the space. Precisely what controls each channel has depended on the mixer, but most mixers share standard features.
