UNPACKING AND INSTALLATION

Although it is neither complicated to install nor difficult to operate your set, a few minutes of your time is required to read this manual for a properly wired installation and becoming familiar with its many features and how to use them. Please take great care in unpacking your set and do not discard the carton and other packing materials. They may be needed when moving your set and are required if it ever becomes necessary to return your set for service. Never place the unit near radiators, in front of heating vents, to direct sun light, in excessive humid or dusty location to avoid early damage and for your years of quality entertainment. Connect your complementary components as illustrated in the following page.

INPUT CONTROL PART

1. PEAK INDICATOR

This indicator detects peak level after the EQ. It will light red at 3dB before clipping to warn that clipping level has nearly been reached.

2. TRIM [GAIN CONTROL]

The gain control adjusts the gain of the input according to the relevant input sound source. Gain adjusting range of the this gain is 44dB. For Mic input connected to the XLR connector, the range is -16dB~-60dB. For Line input connected to the phone connector, the range is +24dB~-20dB.

3. INPUT SELECTOR

This switch selects the input connector for the channel. When MIC( ) is selected, the input signal will be taken MIC connector. (balanced XLR type) When LINE( ) is selected, the input signal will be taken LINE connector. (balanced XLR type)

4. EQ CONTROL

The equalizer section provides the high and low range at the following frequencies. HIGH : 12KHz, LOW : 80Hz,

15dB, shelving type

5. AUX CONTROL

The volume control the level of the signal that is output to the AUX bus. AUX is placed before the channel fader, it will be not affected by the channel fader.

6. EFX CONTROL

The volume control the level of the signal that is output to the EFX bus. EFX is placed after the channel fader, it will be affected by the channel fader.

Page 5

7. BALANCE CONTROL

The BALANCE knob adjust balance or the L/R position of the stereo module signal. For example if this knob is turned all the way to the left, the signal will be sent only the stereo L and PGM 1, 3 whose assign switchs are pressed. If this knob is turned all the way to the right, the signal will be sent only the stereo R and PGM 2, 4. If the knob is set to the center position, the same amount of signal will be sent to the stereo L and R, and PGM 1~4.

8. PAN CONTROL

This knob adjust the stereo position of the signal between the stereo L and R, and between the PGM 1, 3/PGM 2, 4.For example if this knob is turned all the way to the left, the signal will be sent only the stereo L and PGM 1, 3 whose assign switchs are pressed. If this knob is turned all the way to the right, the signal will be sent only the stereo R and PGM 2, 4. If the knob is set to the center position, the same amount of signal will be sent to the stereo L and R, and PGM 1~4.

9. ASSIGN SWITCH [ST, PGM1~4]

These switchs assign the signal of the input module to the PGM 1~4 output and the STEREO output.

10.

PFL SWITCH

This switch allows you to monitor the per-fader channel input signal through headphone and monitor output. It is convenient to use PFL when you wish to check the sound of the input signal, or when troubleshooting a specific channel.

11.

CHANNEL FADER

This fader controls the output level of the input channel signal, determining the volume balance between channels, The channel fader should be lowered for unused channels.

OUTPUT CONTROL PART

1. EFX RETURN CONTROL

The volume control the input levels from the effect device etc, connected to EFX RETURN.

2. EFX BALANCE CONTROL

This knob assigns the signal of effect return, determining the stereo of the sound.

3. ASSIGN SWITCH [EFX RETURN]

These switchs assign the signal of the EFX RETURN to the PGM 1~4 output and the STEREO output.

4. AUX SEND CONTROL

This adjusts the signal level of the AUX SEND output.

5. EFX SEND CONTROL

This adjusts the signal level of the EFX SEND output.

6. ASSIGN SWITCH [MONITOR AND HEADPHONE]

This switch allows you to monitor the signal of the output section.(ST, PGM 1~4, AUX, EFX)

7. HEADPHONE AND MONITOR CONTROL

This knob adjusts the level of monitor output and the volume of a set of headphones connected to the headphone jack.

8. HEADPHONE JACK

Connect the headphone here. You can monitor the following signal :

The input signal of the each input channel : When the PFL switch ON The output signal of the master section : When the monitor assign switch ON

Page 7

9. ON SWITCH

This switch turn the PGM 1~4, ST on/off. The output signal is on when the switch is pressed in. When off, the output signal will be muted.

10.

MASTER FADER CONTROL

This fader adjusts the signal level to the PGM 1~4, ST.

11.

METER SELECT SWITCH

The meters are dual function LED meter that indicate signal levels as selected by the meter select switch. When meter select switch is off : display of the STEREO L/R output When meter select switch is on : display of the headphone or monitor output

12.

METER DISPLAY SECTION

These meters indicate the output level to the PGM 1~4, and ST or monitor.

13.

PFL INDICATOR

This indicator will light when a PFL switch is turned on.

14.

PHANTOM POWER

This switch turns on/off the phantom power supply for all input channels. Use this switch when you are using condenser microphones. When this switch is turned on, DC +48V will be supplied to pin 2 and 3 of each input XLR connector. If you do not need phantom power, be sure to leave this turned off.

It is safe to connect balanced dynamic microphones or line level devices even if this switch

is on, but connecting unbalanced devices or device whose transformers are center-grounded will cause hum or malfunctions. Indicator will be light when PHANTOM switch is on.

15.

POWER SWITCH

The power switch is used to turn on and off the AC main power. The indicator will light when POWER switch is ON.
