Safety Instructions

IMPORTANT SAFETY INSTRUCTIONS

Observe all instructions and follow warnings marked on the equipment and in the user’s manual.
Connect the equipment only to a source of proper mains voltage.
Do not attempt to switch on any equipment that has been dropped, that is damaged, or has
had liquid penetration, or if malfunctions have occurred and their nature requires a repair action. The
supply cable shall be made by a person having proper qualications.

WARNING

The equipment is designed in Class I and shall be connected to a wall socket having

SD8

protective earthing.
The mains plug and supply cable shall remain easy accessible, as this is used for disconnection of the
equipment from the supply source if necessary.
Never interrupt earthing due to safety reasons.
Do not place the equipment close to heating bodies or other sources of heat and protect it against
direct sunlight.
The equipment must not come into contact with open ames.
Ventilation of the equipment must not be obstructed by covering of ventilation openings.
The equipment must not be exposed to dripping or splashing liquid or water and excessive humidity.
Any object lled with any liquid shall not be placed on the equipment.

The triangle with a symbol of a lightning marks parts of the equipment under
life jeopardizing voltage, whose values may cause an injury from electric
shock.

The symbol indicating that the equipment is manufactured in compliance
with EU standards.

The triangle with a symbol of an exclamation mark in the text marks
important instructions for operation, setting and maintenance.

BASIC DESCRIPTION

Safety Instructions

The SD8 is an 8-channel microphone preamplier combined with a line amplier. It is designed for
primary processing of microphone signals. Impedances of the SD8 inputs are properly adapted to
most of the microphones used, the signals are amplied and the inputs, thanks to their low imped­ance - (50 ohms) can drive, without any loss, long symmetrical lines to the mixers - (up to 500m).
It is suitable to place the SD8 directly on the stage, close to the active microphones as practical, as
most microphones cannot provide loss-free excitation of long cables. 48V phantom supply is available
to supply condenser microphones. Each channel is equipped with two identical outputs that can be
used for connection of a main mixer and monitoring desk, recording device, etc.
