Detailed Description

Headphone (Phones) output

In addition to the Main and Alt loudspeaker outputs, SiX has a stereo headphone

output on a ¼” Stereo Jack, on the upper connector panel above the Power

indicator.

The headphone level is controlled by the PHONES knob which is above the Monitor

Level control. By default, the headphone output follows the Monitor SOURCE

selection. However, the headphone output can also be switched to monitor Stereo

Cue buses 1 & 2 independently of the Monitor selection, using the ST CUE 1

and ST CUE 2 switches above the level controls. These switches intercancel with

the uppermost switch taking priority. The Stereo Cue feeds to these switches are

before the additional features of the Foldback section, i.e. before Talkback and

the External Source selection. This prevents the Talkback feeding back into the

headphones when both the Foldback/Talkback Mic and the Headphones are being used.

Monitor Source section

The MON SOURCE section controls the signals fed to the Monitor Level and the Headphone

Outputs. A block diagram of this section can be seen on the next page. A powerful and

unusual feature of the Monitor Source section is that the sources sum, rather than switch.

This allows monitoring of external signals alongside the main mix buses while using these

buses to feed audio recorders or other ‘clean’ feeds.

Buttons in the MON SOURCE section SUM signals into the monitor outputs as follows:

- MAIN - Main Bus - after fader, insert, compressor and source summing

- BUS B - Bus B after the level control and MUTE switch

- EXT 1 - External Input 1 after the level control

- EXT 2 - External Input 2 after the level control

PLEASE NOTE: IF NONE OF THE ABOVE BUTTONS ARE SELECTED,

THERE WILL BE NO SIGNAL TO THE MONITORS

External 1 and 2 Levels

Above the EXT 1 and EXT 2 monitor source switches are the level controls for the relevant

External inputs. These level controls adjust the External level between off and +20 dB,

with a detent at unity. The law of these controls is designed to offer more ne control

around unity gain, with a greater degree of tapering in the level control law towards the

end positions. The External level set by these controls affects wherever the Ext signals are fed in the console (e.g. to the external

summing into the Main Bus).

The block diagram for the Monitor Source and External Input section is shown on the next page.
