POWER SUPPLY ENG 18 POWER SUPPLY 18.1 FRONT VIEW 18.2 REAR VIEW 18.3 DESCRIPTION The Oxygen 4 Power Supply (PWS) consists of a power transformer, selectable for 115 VAC or 230 VAC operation, rectifiers, filter capacitors and voltage regulators on a circuit board. The power supply is protected by a replaceable AC mains fuse located in the power entry socket plus internal fuses on the transformer‟s secondary outputs and self-protected current-limiting regulators.
ENG POWER SUPPLY 18.4 PWS RELAYS The power supply features two built-in relays separately controlled by the MONO modules. They are designed to illuminate external Studio and/or Control Room Warning/On Air lights (such as Mr Light by Axel Technology) showing that one or more microphones are „on air‟. Relays are intended for low voltage electric loads (e.g. 24 V), up to 10 A. FOR SAFETY AND TO PROTECT THE OPERATOR FROM HIGH VOLTAGE SHOCK, NEVER CONNECT AC MAINS TO PWS RELAYS.
POWER SUPPLY ENG 18.6 MAIN AC VOLTAGE SETTINGS Before connecting the Oxygen 4 to mains power, determine the actual mains voltage and confirm that the Oxygen 4 has been configured correctly. As could be expected, an incorrect mains configuration could seriously damage the unit. If the unit is to be used with a mains voltage different to that for which the unit is supplied, set the voltage change-over switch, which is placed inside the box, closed to the AC socket and the AC filter.
POWER SUPPLY ENG If one or more LEDs are still switched off: - open the PWS cover - verify the integrity of the 2 fuses on the PCB and replace the burned ones (fuses are rated to 1.6 A T) - close up the cover - connect the AC Mains cord only - switch on the power supply again and check whether all LEDs glow.
METERBRIDGE ENG 19 METERBRIDGE 19.1 VIEW 19.2 DESCRIPTION The Oxygen 4 mixer is fitted with VU / PPM meters. VU meters respond to an average signal level, whereas PPMs respond to peak changes (The PEAK LEDs are activated by the shortest transient peak, but remain „on‟ long enough to provide easy recognition). If a 1kHz sinusoidal signal is input to the mixer and the amplitude adjusted such that the level at the master output is 0 dBm, the meters will read 0 VU (the orange LED will glow).
