CONNECTIONS

For more information on connections, please refer to the next chapter.

Be sure to turn off the mixer before you make changes to the different connections.

In this manual we talk about "line inputs". This is a global name for inputs with a level between 750mV and 2V. This includes tuners, videos, CD-players, etc.

FUNCTIONS

MONO MICROPHONE/LINEINPUT CHANNEL

1. 3 PIN FEMALE XLR SOCKET INPUT

Balanced input wiring: Pin 1 = Ground (sleeve)

Pin 2 = Positive signal

Pin 3 = Negative signal

Unbalanced input wiring:

Pin 1 = Ground

Pin 2 = Signal

Pin 3 = Ground

Input impedance: 2k Ohm

Input sensitivity: 0.8mV RMS (-60dB)

2. 1/4"STEREO JACK SOCKET INPUT

Balanced input wiring:

Tip = Positive signal

Ring = Negative signal

Sleeve = Ground

Unbalanced input wiring:

(Mono jack plug will automatically give this)

Input impedance: >50K Ohm

Input sensitivity: 25mV RMS (-30dB)

3. GAIN CONTROL

Allows maximum input signal control and will accommodate most microphones of both low or high impedance to 600 Ohm as well as Phantom Power (48 Volt) types. The line input can be anything from keyboard through to line level feeds from other equipment. Gain range:

XLR input +15 to +60dB

Jack input -15 to +30dB

4. CLIP LED

This warning will illuminate 4dB before clipping and will remain on for a short period. For optimal input channel running level, adjust Gain Control until Clip indicator illuminates while signal peaks are present. Then adjust the gain setting until Clip indicator is off. This will give optimal signal to noise.

5. EQ CONTROL 'HIGH'

This control allows 16dB of cut or boost to the high frequencies.

6. EQ CONTROL 'MID'

This control allows 16dB of cut or boost to the mid frequencies.

7. EQ CONTROL 'LOW'

This control allows 16dB of cut or boost to the low frequencies.

8. AUXSEND1

This auxiliary send control is 'Post-fade' and can be used to control the mix of inputs being processed by effects, etc. Its level will change with the channel fader (12).

9. AUXSEND2

This auxiliary send control is 'Pre-fade' and can be used to control the mix of inputs to an independent output such as monitoring. Its level will not change with channel fader (12).

Note: the Post-Fade option can only be selected by your service engineer.

10. PAN CONTROL

This control is used to set the stereo balance of the input signal and can 'Pan' it fully to the left or right.

11. PFL SWITCH

This switch and indicator allows pre-fade listen of input signals through the headphone and Led meters (useful while setting gains or trouble shooting).

12. 60mmFADER

This slide control provides level control of input signal to the main stereo mix output and will also control the Post-Fade Aux Send 1.

STEREO LINE INPUT CHANNEL

1. LINE INPUT LEFT OR MONO - 1/4" Mono Jack Socket

If the input is connected to a mono source use this connection only as the signal will automatically be routed to the right input also.

Input wiring:

Tip = Signal Sleeve = Ground

Input impedance: 10K Ohm

Input sensitivity: 24.5mV (-30dBm)

2. LINE INPUT RIGHT - 1/4" Mono Jacket Socket

Input wiring:

Tip = Signal Sleeve = Ground

Input impedance: 10K Ohm

Input sensitivity: 24.5mV (-30dBm)

3. PAD SWITCH

Operation of this switch reduces the input sensitivity by 10Db allowing it to be used with high output devices such as CD players as well as musical instruments.

4. GAIN CONTROL

The panel marking at 0dB is a true reference to 0dBm when the -10dB Pad is engaged.
Range: +10dB

5. CLIP LED

This warning light will illuminate 4dB before clipping and will remain on for a short period. For optimal input channel running level, adjust Gain Control until Clip indicator illuminates while signal peaks are present. Then adjust the gain setting until Clip indicator is off. This will give optimal signal to noise.

Note: If EQ controls are altered this Gain/Clip setting will need adjustment.

6. EQ CONTROL 'HIGH'

This control allows 16dB of cut or boost to the high frequency content of the input signal.

7. EQ CONTROL 'MID'

This control allows 6dB of cut or boost to the mid frequencies.

8. EQ CONTROL 'LOW'

This control allows 6dB of cut or boost to the low frequencies.

9. AUXSEND1

This auxiliary send control is 'Post-fade' and can be used to control the mix of inputs being processed by effects, etc. Its level will change with the input fader (13).

10. AUX SEND 2

This auxiliary send control is 'Pre-fade' and can be used to control the mix of inputs to an independent output such as monitoring. Its level will NOT change with input fader.

Note: The Post-fade option can only be selected by your service engineer.

11. BALANCE CONTROL

This control is used to set the stereo balance of the input signal and can pan it fully to the left or right.

12. PFL SWITCH

This switch and indicator allows pre-fade listen of input signals through the headphone and Led meters (useful while setting gains or trouble shooting).

13. 60mm FADER

This Slide control provides level control of input signal to the main stereo mix output and will also control the Post-fade Aux Send 1.

This Slide control is used to set the required overall output level to the power amplifier (or other equipment). The calibration shows a suggested nominal running level, referenced '0' (10dB boost is available if required).

10. ON INDICATOR

This led indicates that the mixer power is on.

11. PHANTOM SWITCH

This switch is recessed to prevent accidental operation and has a corresponding red LED indicator; it should NOT be operated while the mixer is live.

NOTE:

It should be pre-selected during setting up with the main output faders and MIC input gain controls down.
- ALL XLR MIC inputs will be phantom powered when selected. Some microphones that do NOT require phantom supply may not operate or are damaged - check instructions.
