NOTE : This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These

limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the interference at his own expense.

This symbol is intended to alert the user to the
presence of uninsulated “dangerous voltage” within
the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to
persons.

This symbol is intended to alert the user to the
presence of important operation and maintenance
(servicing) instructions in the literature accompanying
the appliance.

Caution: To prevent electric shock do not use this (polarized) plug with

an extension cord, receptacle or other outlet unless the blades
can be fully inserted to prevent blade exposure.

Attentions: Pour prévenir les chocs électriques ne pas utiliser cette

MP3 (MPEG AUDIO LAYER-3)

MP3 is one of music file formats that can contain music with stereo sound quality as good as audio CD, which is a
type of MPEG as audio, video compression standards. Compression rate is 1MB by 1 minute and thus about
3~5MB are sufficient if recording songs of 3~ 5 min or so. Different from audio CD, a music file made of MP3 can
contain over 130 songs for popular songs or folk songs and playing time is also about 10 hours. MP3 removes
high frequency which a human can not discernable, so it has advantage to compress it to 1/12 or so while
maintaining sound quality equivalent to CD. The data capacity of a music CD is about 50MB, if it is compressed to
MP3, then it's capacity becomes about 4~5MB.

- WMA (WINDOWS MEDIA AUDIO)

WMA is a multimedia compression method developed by Microsoft Corporation and is the technology to compress
only music from 'Window Media Technologies'. It provides same sound quality as the format of MP3 of 128Kbps
with WMA of 64Kbps.
In other words, it has the half file size compared with MP3 and provides same sound quality as MP3.

Operation

Operation

1. Make sure that speakers and input/output cables are properly connected before you plugged in the power.

2. Set all volumes to the minimum position before you turn the power on.

3. Be sure the AC power is correct voltage before you plug into the power cord.

4. When the power button is pressed, the VFD displays and the unit is working.

5. Adjust the each channel volume and the master volume.

6. Adjust the mic channel EQ.

7. Please refer to the CD / FM operation method or Set Up mode section for details.

13. PHANTOM POWER SWITCH

These switches turn the phantom power supply on
or off for each channel.

When the switch is pushed, +24V DC power is
supplied to the pin 2 and the pin 3 of each XLR
jack. Use phantom power when you connect a
condenser microphone, which requires an
external power supply.
NOTE : It is safe to connect most modern dynamic
microphones to the channel inputs when phantom
power is activated. However, some older ribbon microphones may be damaged by phantom power, and
certain unbalanced line level devices may malfunction or produce an audible hum when phantom power is
turned on. Use the phantom power only you use a condenser microphone.
If you press the phantom power switch when the channel volume and master volume is at the high volume
level, it may cause audible pop sound.

14. AUX IN

This is the unbalanced input. This input can be used to connect a tape player or other sound sources.
Input Level : -30dBV ~ +6dBV.

15. PRE/POST OUT

PRE OUT : This is the unbalanced output. This output can be used to record the signal from the unit.

The output level is not controlled by the master volume.
Output Level : 0dBV.

POST OUT : This is the unbalanced output. This output can be used to monitor the signal with a monitor amplifier.

The output level is controlled by the master volume.
Output Level : 0dBV.

16. MIC INPUT : CH1 - CH6 (or LINE INPUT)

These inputs are suitable to receive signal from microphones. XLR inputs are balanced input.
Input Level : -60dBV ~ -16dBV
When other line level source is connected to one of these terminals, adjust the trim volume to -16dB position.

The phantom switch must be off or not the line level source may be damaged.

17. INPUT GAIN CONTROLS (TRIM VOLUME)

These are trim volumes of each mic inputs to control the input gain.
When adjusting the input gain, make sure that the levels are not set too high, or not it may cause noisy or
distorted output.
