CONTROLS AND CONNECTIONS

AUXILIARY OUTPUTS SECTION:

This section includes 6 identical channels (A, B, C, D, E and F).

The following description is valid for each of them.

43 ➤ A / B / C / D / E / F outputs level: 12 segment LED array gives

istantaneous reading of A, B, C, D, E and F outputs level.

44 ➤ HIGH / MID kHz / MID dB / LOW: 3-band Equalizer with para

metric control of the mid range for the A, B, C, D, E, F monitor

outputs. The High and Low controls act on xed frequency bands,

the Mid control allows to choose the frequency to be boosted or

cut.

HIGH: adjusts the amount of boost or cut in the high frequency

range (±15dB@15kHz). Turning the control clockwise increases the

amount of high frequencies, counter-clockwise decreases it.

The response is at at the center position.

MID kHz: chooses the frequency to be boosted or cut (0,18÷3kHz).

MID dB: adjusts the amount of boost or cut (±15dB) in the frequen-

cy choosen by means of the MID kHz control.

Note: If the MIDdB control is set at '0' (centre) there will be no alteration

in the mid frequency band (independently of the MIDkHz control setting).

LOW: adjusts the amount of boost or cut in the low frequency

range (±15dB@50Hz). Turning the control clockwise increases the

amount of low frequencies, counter-clockwise decreases it.

The response is at at the center position.

45 ➤ PFL: this push-button allows to check the level of the aux

output signal by means of the PFL level indicator (57) and to listen

to it on headphones, even if the fader is closed. It is so possible to

adjust the aux mix and output equalizer without sending it to the

output. If more than one PFL switch is on, the phones amplier and

the PFL LED indicator will receive the sum of the selected signals.

Note: To allow headphone listening of a PFL signal, the PFL switch of the

master module's headphone amplier (56) must be pressed.

46 ➤ A, B, C, D, E and F output level fader.

●

connections:

47 ➤ A / B / C / D / E / F AUX OUTPUTS: each output is tted with

an unbalanced XLR socket and a stereo jack socket (for the inser-

tion of external accessories)

■ Connect the A, B, C, D, E, F output sockets to the inputs of the

self-powered monitors. Adjust the monitor sends controls on each

channel (A, B, C, D, E, F controls), the tone controls (44), as well as

the aux volume faders (46).

Note: The stereo jack socket may also be used as unbalanced jack output,

using a standard mono jack. In this case the corresponding XLR output will

be disconnected. You may thus use XLR or Jack sockets according to your

needs.

■ Each output can drive up to 10 parallel connected active speaker

enclosures or power ampliers.

MASTER SECTION:

48 ➤ L / R outputs level: 12 segment LED arrays give istantaneous

reading of L and R outputs levels.

49 ➤ L/R MASTER: volume faders for the left and right master

outputs.

50 ➤ 10-band stereo graphic EQUALIZER.

51 ➤ EQ / FLAT: equalizer on/off switch.

52 ➤ MONO: volume control for the mono output.

53 ➤ PRE/POST: the signal to the 'mono' output may be selected

independent from master L/R faders (PRE) or dependent from the

fader postion (POST).

54 ➤ CTRL ROOM: level control for the CONTROL ROOM stereo

output (63).

55 ➤ PHONES: level control for the phones output.

56 ➤ PFL L/R: in normal conditions, the headphones amplier

receive the master L/R signal (pre fader), but pressing this switch

it is switched to the selected PFL signal. If more than one PFL

switch is selected, the headphones receive the sum of all the

selected signals.

57 ➤ PFL: PFL signal LED level indicator (12 segment LED array).

58 ➤ TAPE IN VOL: sets the level of the signal at the 'Tape in'

sockets.

59 ➤ PHANTOM 48V D.C.: master phantom power switch.

It enables the individual phantom power switches on mono input

channels. If no phantom powered microphones are used with the

mixer, it is suggested to switch off this switch.

60 ➤ POWER: mains power switch.

●

connections:

61 ➤ L /R MASTER OUTPUTS: each output is tted with an

unbalanced XLR socket and a stereo jack socket (for the insertion

of external accessories).

■ Connect the L/R master outputs to the inputs of the self-powered

speaker enclosures or to the inputs of the power ampliers.

Adjust the volume fader on each channel as well as the L/R master

volume faders.
