Oxygen 5 2.1 INTRODUCTION Stereo module is easily and readily configurable as line/line or line/phono depending on the user requirement. Input A is a line stereo input, while Input B (stereo) may be set through internal jumpers as line stereo or phono stereo (with built-in R.I.A.A. preamplifier). The module provides also a REMOTE interface to connect or control external equipment.

Oxygen 5 3.1 INTRODUCTION The Mono module features two mono inputs (Input A and Input B). Input A is factory pre-set on microphone level but it can be also easily set on line level. Input B is set only on line level.
Oxygen 5 3.6 GAIN INPUT A TRIMMER You can use the multi-turns trimmer to fit the Micro level to the input level of the pre- amplification circuit. It’s highly recommended if the Gain potentiometer doesn’t amplify or attenuate enough the Micro signal. Adjust the trimmer to reach the 0 dB PFL output level corresponding to the Gain control central position (read the level on the VU-Meter).
On/Off function either in local mode (through related button) or in remote mode, through an external device (‘DJ Console’ by Axel Technology) linked to the SUB module. Thanks to it, the speaker (normally located in studio) is able to remotely switch the mixer module related to his microphone.

4.1 SEND OUTPUT The Send output allows to send to the telephone line - through an external phone hybrid (e.g. MACROTEL7 by AXEL Technology) - the signal composed by the sum of the output signals from every module except the Telco one.
Oxygen 5 THE CONNECTOR SUPPLIES THE FOLLOWING VOLTAGES: • + 6 V (pin 6) • GND (pin 1) These voltages can be used to polarize external optoisolator devices. We suggest to use a Ω (or more) resistor in series connection with the phototransistor emitter to prevent the risk of damages to the photocoupler, due to extra-high current.
Oxygen 5 4.8 PANORAMIC CONTROL The PAN control allows sound balancing between Left and Right output channels. In the central position the gain is 0 dB for both channels. 4.9 MASTER AND SUB SWITCHES MASTER and SUB switches connect the module to the Master and/or Sub outputs.
