Oxygen 7Oxygen 7 - STEREO MODULE

Pag. 30

8.4 INTRODUCTION

Each STEREO module has two selectable stereo inputs which comes

factory preset for Line (input A) and Line (input B) levels or Line (input

A) and Phono/RIAA (input B) levels, depending on the customer

requirement. Normally input A is selected but by pressing B SEL button

the alternative input is selected.

There is individual preset gain adjustement for A input via jumpers (see

8.8) and the selected source is fed through a phase switch and a common

gain trim control giving a further ± 10dB of gain adjustment on the front

panel.

The channel support real world broadcast applications, where left and

right signals may, or may not, be an actual stereo pair. Routing buttons

allow each left and right input to be assigned to the left output bus, to the

right output bus, to both output buses

A three band equaliser is also fitted as standard.

The Auxiliary (AUX) send may be switched pre or post fade.

The signal is routed via a balance control for small adjustments to the

stereo image and the three stereo routing switches to either the main

stereo programme (Master) or the two stereo su/jointfilesconvert/268126/bgroups (Sub 1 and Sub

The whole signal path throughout the module is controlled by Vca circuits.

The DUCK switch allows the module to be attenuated from the master

ducker circuits (Mono modules have a jumper fitted to make it a source for

the automatic ducker circuits).

The PFL switch makes the pre-fade signal available for monitoring.

The module provides indipendent Start/Stop controls for external

equipment connected to Input A or B. The remote Start/Stop operation

can be jumper configured to be either momentary or latched, to give a

continuous output - a feature that may be required for some types of

equipment.

The remote Start Stop commands are connected to a 15 way D type and

are fed from opto-isolators.

Jumper selection allows You to configure Start/Stop commands by fader

or by using the Start button.
