■ FEATURES
1. BALANCE Knob
This knob adjust the stereo input balance for each channel. At the center position,
the left and right signals are at the same level. Rotating the knob clockwise or
counterclockwise will shift the sound field to the right or left respectively.
2. OVERLOAD Indicator
This indicator light when the mixed signal level is too high. If these LEDs light
frequently, lower channel counterclock wise.
＊These indicators are not affected by the position of the MASTER volume slider.
＊These indicators light at 6 dB below the clipping level
(the point at which distortion becomes audible)
3. POWER Indicator :
This indicator lights when the LOOP MIXER is turned on.
4. PHONES Knob : This knob controls the headphone volume.
＊
5. GAIN Knob : This knob adjust the input volume for each channel. They are
used to optimize the signal level to avoid distortion. Rotating a GAIN knob clockwise
will increase the volume, while rotating it counterclockwise will decrease the volume.
When a microphone is connected to one of the INPUT jack, be sure to rotate the
corresponding GAIN knob completely clockwise (near to the “MIC” position).
＊ Each GAIN knob controls the L/R signals in each channel simultaneously.
The headphone volume is not affected by the Position of the MASTER Volume slider.
6. CHANNEL VOLUME Slider :
This slider provide volume control for each channel. Set these sliders relative to one
another to achieve the best audio mix.
＊ Each VOLUME slider controls the L/R signals in each channel
simultaneously.
7. MASTER VOLUME Slider : This slider adjusts the overall output of the
LOOP MIXER.
＊The MASTER slider does not affect the output level of the REC OUT jacks or the
PHONES jack.
8. PHONES Jack (Stereo Mini Type) : Connect stereo headphones to this
jack.
9. AC ADAPTOR Jack : Connect an AC adaptor to this jack.(Be sure to use the
adaptor specified for your country)
10. POWER Switch : Power ON/OFF of LOOP MIXER.
11. LOOP OUT Jack : Connect LOOP CABLE to another LOOP MIXER’s
LOOP IN Jack. You can rehearse or jam while monitoring with head phones.
12. LOOP IN Jack : Connect LOOP CABLE to another LOOP MIXER’s LOOP
OUT Jack. You can rehearse or jam while monitoring with headphones.
13. OUTPUT Jack (Stereo Mini Type) : This jack provide output of the final
mixed signals. They can be connected to a PA system, or to the inputs of another mixer.
14. REC OUT Jack (Stereo Mini Type) : This jack is convenient for
recording direct to a record device. (Convenient further still because the
output level is
not
affected by the MASTER Volume slider)
15. CH1~5 INPUT Jack (Stereo Mini Type) : Devices (electronic
instruments or mics, for example) with TRS mini plug should be connected to these
inputs. ( To connect a monaural device, you can use the plug adaptor supplies with the
unit)
Thru : Pass Through (Normal Mode).
Lo-Z : When a high impedance equipped source (like an electric guitar) causes noise
or crosstalk, switch to Lo-Z (low impedance) then the noise or crosstalk level can be
reduced.
＊Note : Switching to Lo-z,the input signal level will be reduced.
Please refer to our website for our locations list where to buy.
