OPERATING MANUAL AND USER GUIDEOPERATING MANUAL AND USER GUIDE

Each mono channel each feature a three band Equalization

("EQ") section. Each band is chosen from the prime

frequencies for most musical applications, and allows up

to 15 decibels of boost (increse) or cut (decrease) of the

signal in the tone range for which it controls. In the center-

detent position (0), the equalizer is bypassed (flat)and the

control has no effect on the tanal characteristics of the

signal. The HIGH control is centered at 12KHz. The MID

control is centered at 2.5kHz and the LOW EQ control is

1. Low Impedance (Low Z) MIC Input

The law noise, high headroom "law Z" MIC inputs are for

use with balanced, law impedance dynamic or conderser

power. If your condenser microphone appears not to be

working check that the phantom power switch (master

section - 5) is engaged.

2. LINE IN

These 1/4" Tip, Ring, Sleeve (TRS) jacks are designed to be

connected with (-10 to +4dBu) balanced or unbalanced

line level sources.

3. GAIN Control

In order to achieve the best signal to noise ratio and

adequate dynamic range, the input preamp level of the

Mit/Line channels is adjusted with o GAIN control on

each mono channel. Set the GAIN control by watching

the LED bar-graph meters-above the MAIN MIX level

control in the Master section of the mixer- while the

signal source for that channel is active (whether it be a

microphone or an instrumetn connected to the LINE IN of

the channel). The ideal level is between 0dB and +6dB

on the bar 9raph meters. If the CLIP LED on the channel

lights up consistently, the GAIN control is set too hi9h. It is

acceptable for the CLIP LED at flash periodically especially

with loud instruments like drums or during peak sound

levels during loud portions of a performance.

4. CLIP LED

The CLIP LEDs (on channels 1 to 4) will light up when the

input signal is driven too high This indicates that the signal

is overloading the preamp and causing distortion.

5. EQ Section

centered at 80Hz.

6. EFX Section

The EFX control allows you to mix the dry (i.e. no effects)

sound with the effects signal. Same instruments and voices

sound better with a different level of the effects added in

to the clean signal. This control allow you to mix the effects

in as you like. Sometimes the sound by itself sounds good

with a certJon level of effects but when mixed with the other

channels signals, the sound does not sound the same. You

can tailor the sound of each input by adjsuting this control.

7. Pan and Level

Pan Control: On each mono channel, the PAN control

adjusts the left/right balance of the mono signal being

sent to the left and right MAIN MIX outputs.

8. The Channel LEVEL Control

The Channel LEVEL knob allows for control of the level

of the signal that is being sent to the MAIN MIX master

volume control. Adjust each channel level control to accquire

the best "mix" , or balance of signals, from each input.

Stereo Channel Inputs

operates as a mono channel.

2. EFX

This control allows you to adjust any effects you want to

add to the signal of your stereo (2 channel) device in the

same fashion s the mono channels.

1. EQ(HIGH/LOW)

Each stereo channel feature a two band Equalization

section. Each band is chosen from the prime frequencies

for most musical applications, and allows up to 15 decibels

of boost (increse) or cut (decrease)of the signal in the tone

range for which it controls. In the centerdetent position (0),

the equalizer is bypassed (flat)and the control has no effect

on the tanal characteristics of the signal. The HIGH control

is centered at 12KHz. The LOW EQ control is centered at

80Hz.

Each of the stereo channels feature two line level inputs

withl/4'' Tip/ Ring/Sleeve(TRS) jacks for both balanced and

unbalanced left and righ input isgnals. These inputs can

occommodate both stereo and mono inputs. When using a

mono source, connect the cable to the LEFT (MONO) input

only. Stereo Channels have stereo inputs with left and right 1/4"

Tip/Ring/Sleeve (TRS) input jacks. LEFT (MONO) input: When

only one plug is inserted into the LEFT jack, the channel

This section also consists of two sets of three output jacks.

These are the bottom row of jacks in the "2TK OUT" section

PAN Control

3. PAN and LEVEL

On a stereo channel, with a stereo input connected, turning

the PAN control to the left will case right input's

signal level to decrease. Turning the PANcontrol fully

right on a stereo channel will cause the left Jnput's signal

level to decrease. If a mono input is connected to a stereo

channel, the PAN control will function as a PAN

control by adjusting the left/right PAN of the mono

signal being sent to the left and right MAIN MIX outputs.

4. Stereo Channel Level Control

The stereo channel level control allows for control of both

the left and right signals being sent to the MAIN MIX

master volume control. If a mono input is connected to a

stereo channel, the channel functions like a mono channel.

Master Section

The master section on the right side of the mixer controls

the final gain stage of the mixed signals from the input

channels. The MAIN MIX control allows for the adjustment

of the overall output level of the mini mixer.

POWER LED & Signal Metering

1. POWER LED

This amber LED lights indicating power is on for the mixer.

2. Level Meters

The signal level of the MAIN MIX output is displayed on the

4 segment LED bar-graph meters. Levels shown are -20, 0,

6 and CLIP.

3. 2TK IN

This section consists of two sets of three input jacks. The top

row of jacks are the "2TK IN" jacks which are a 1/8" stereo

jack and a left and right RCA jack. These inputs allow for

the introduction of an external stereo signal to the mixer.

This signal is controlled by the 2TK IN volume control and

the 2TK TO PHONES switch as well as the 2TK TO MAINS

switch. When the 1/8" 2TK IN jack is used, it takes priority

over the RCA 2TK IN jacks.

These outputs allow for the routing of MAIN MIX stereo

signal out of the mixer. This signal level is controlled by the

MAIN MIX volume control. When the 1/8" 2TK OUT jack is

used, it takes priority over the RCA 2TK OUT jacks.

a convenient 1/8" mini stereo headphone jack is also

included, allowing for portable headphones and ear

aware that very high volume levels are possible from this

output. Make sure the level is set all the way down before

connecting headphones.

8. FX Master Control

The FX Master Control allows you to choose which effect

you want to use. The FX to MAIN control allows you to

send as much of the effected sound to the MAIN output

controls. Keep in mind that you are adding signal and make

sure you are not overdriving the main output. The FX

on/off switch is a good way to quickly compare the "wet"

and "dry" sound.

9. POWER Switch - On/Off

This slide switch turns the unit on and off. Always power

down the mixer when it is not in use. Be sure to turn off all

system amplifiers or powered speakers before turning off

the mixer.
