Telex Q II - FOH specifications Do not Disconnect the Mains Earth

Page 14

Rack mounted equipment which has unbalanced inputs and outputs may need to be electrically isolated from the equipment rack and/ or other equipment to avoid earth loops.

DO NOT DISCONNECT THE MAINS EARTH.

Connect all equipment in a logical sequence, starting with the monitor systems, followed by the multitrack and then the stereo machines and the peripheral devices and isolate any earth loop problems as they occur. It is very difficult to rectify a problematical installation after everything has been connected due to interaction between the various earth loops.

The Console is supplied with 1 power supply unit 3U high (5.25"), 19" rack mounting. The PSU supplies the console with +18V, - 18V, +48V phantom and Audio Ground (0V). Connection between supplies and console is a cable, terminated at both ends by polarised Harting multiway connectors. At the console the connector is located on the rear panel of the console.

The normal length of the PSU-Console cables is 25 feet (8 metres).

The power supply requires the following Mains supplies :-

220-240 Volts AC, 6.3 A (Maximum current ratings) 100-120 Volts AC, 10 A (Maximum current ratings)

and is connected to the AC Mains via standard IEC 3 pin lead.

The PSU has an integral low-noise cooling fan and should be provided with at least 1U (1.75") of rack space above and below it.

WARNING - ENSURE THAT THE CORRECT VOLTAGE HAS BEEN SELECTED ON THE PSU BEFORE SWITCHING ON THE UNIT.

The selection of the mains input voltage is made by removing the fuse holder from the rear panel of the PSU, and replacing it in the correct orientation for the local voltage supply. Ensure that the correct value fuse is fitted to correspond to the supply.
