INTRODUCTION
① POWER Indicator
When the POWER switch ⑯ is ON, the LED will turn GREEN. When the battery voltage level becomes too low
for proper operation, the LED will turn RED. When this happens, replace the batteries with fresh "AA" alkaline
batteries.
② Channel 1, 2, 3 & 4 Input LEVEL Controls
Each knob controls the input volume of the microphone connected to the corresponding INPUT
⑬ . Zero is the lowest (quietest) setting while 10 is the highest (loudest). For the best sound with the lowest
possible noise, increase the input level control until the corresponding VU Meter ⑧ peaks at 0 dB.
③ Channel 1, 2, 3 & 4 PAN Controls
Each channel of the mixer has an adjustable PAN control (the outer-ring at the base of the Input LEVEL
control ② ). When the PAN Control is in the center position, an equal amount of sound will come from
OUTPUT L ⑰ and OUTPUT R ⑱ for any microphone or line level device connected to the corresponding
INPUT ⑬ . Turning the PAN control counter-clockwise will decrease the sound output in the Right channel.
Turning the PAN control clockwise will decrease the sound output in the Left channel.
④ MASTER Level Control
The MASTER knob controls the overall volume of all connected sources (microphones and/or line- level
devices). For the best sound with the lowest possible noise, try to keep this control set at its midpoint while
maintaining the VU Meters ⑧ at the 0 dB range with the input LEVEL controls ② .
⑤ Channel 1, 2, 3 & 4 LIMITER Switch
Each INPUT channel ⑬ has a switchable LIMITER. After setting the input LEVEL ② , turn this switch to ON. The
LIMITER circuit acts as a safety and reduces the possibility of overload distortion from very loud sounds
without a ecting normal sound volume. If you prefer the overall sound quality of the mixer without the
LIMITER circuit engaged, leave the switch OFF.
⑥ Channel 1, 2, 3 & 4 HPF (High Pass Filter) Switch
Each INPUT channel ⑬ has a switchable High Pass (= Low Cut) Filter. When turned on, it will cut input
frequencies lower than 100Hz. This filter is useful for removing unwanted low frequencies, such as wind and
air-conditioning noise. For most noisy recording environments, engaging the High Pass Filter will improve
overall sound quality.
⑦ Input PEAK Level Indicators
Each INPUT channel has 2 PEAK Level Indicators on the left side of the LEVEL control knob ② .These Indicators
are provided to help set precise input LEVEL adjustments. The lower LED indicates the level of the input
electronically prior to the LEVEL control while the upper LED indicates the level electronically after the LEVEL
control. The lower LED lighting RED indicates that the item connected to the mixer's INPUT ⑬ has a signal
that is too high and should be reduced either by changing the INPUT LEVEL switch ⑭ setting or at the device
itself. The upper LED should only light RED occasionally. If this LED stays lit continuously, lower the input
LEVEL ② and/or change your INPUT LEVEL ⑭ settings. These LEDs help reduce signal overload and
distortion.
⑧ VU Meters L and R
The VU Meters will show either the output volume level of LINE OUT ⑰ & ⑱ or input volume level of CAMERA
RETURN ㉖, whichever is selected by the Monitor SELECT switch㉒.
