General notes 1 General notes This user manual contains important information on safe operation of the device. Read and follow all safety notes and all instructions. Save this manual for future reference. Make sure that it is available to all persons using this device. If you sell the device to other users, be sure that they also receive this manual. Our products are subject to a process of continuous development. We therefore reserve the right to make changes without notice.
General notes Signal word Meaning DANGER! This combination of symbol and signal word indicates an immediate dangerous situation that will result in death or serious injury if it is not avoided. CAUTION! This combination of symbol and signal word indicates a pos‐ sible dangerous situation that can result in minor injury if it is not avoided.
Safety instructions 2 Safety instructions Intended use This device is intended to be used to distribute incoming audio signals to several device internal outputs. Use the device only as described in this user manual. Any other use or use under other operating conditions is considered to be improper and may result in personal injury or property damage. No liability will be assumed for damages resulting from improper use.
Safety instructions Safety DANGER! Danger for children Ensure that plastic bags, packaging, etc. are disposed of properly and are not within reach of babies and young children. Choking hazard! Ensure that children do not detach any small parts (e.g. knobs or the like) from the unit. They could swallow the pieces and choke! Never let children unattended use electrical devices. DANGER! Electric shock caused by high voltages inside Within the device there are areas where high voltages may be present.
Safety instructions DANGER! Electric shock caused by short-circuit Always use proper ready-made insulated mains cabling (power cord) with a pro‐ tective contact plug. Do not modify the mains cable or the plug. Failure to do so could result in electric shock/death or fire. If in doubt, seek advice from a regis‐ tered electrician. CAUTION! Possible hearing damage With loudspeakers or headphones connected, the device can produce volume levels that may cause temporary or permanent hearing impairment.
Safety instructions NOTICE! Risk of fire Do not cover the device nor any ventilation slots. Do not place the device near any direct heat source. Keep the device away from naked flames. NOTICE! Operating conditions This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and strong vibrations.
Safety instructions NOTICE! Power supply Before connecting the device, ensure that the input voltage (AC outlet) matches the voltage rating of the device and that the AC outlet is protected by a residual current circuit breaker. Failure to do so could result in damage to the device and possibly injure the user. Unplug the device before electrical storms occur and when it is unused for long periods of time to reduce the risk of electric shock or fire.
Features 3 Features n n n n n n Two operation modes (2 in 4 & 1 in 8) switchable Eight separately controllable outputs Two link outputs XLR in and outputs Efficient circuit design for minimum distortion and lowest noise level 19" housing (1 RU), installation depth 12 cm DS 2418 11
Installation and starting up 4 Installation and starting up Unpack and carefully check that there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the device against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively. Establish all connections as long as the unit is switched off.
Installation and starting up XLR connection for signal in and outputs XLR mounting sockets are provided for signal inputs. XLR mounting plugs are provided for signal outputs. Drawings and descriptions explain the pin assignment.
Connections and operating elements 5 Connections and operating elements Front panel audio splitter 14
Connections and operating elements 1 Mains switch to turn the unit on or off. 2 Indicator LED for operating mode 2–4 In this mode, the audio signals on INPUT CHA and INPUT CHB are distributed to the associated outputs CH1 to CH4 and CH5 to CH8 (stereo operation). 3 Indicator LED for operating mode 1–8 In this mode, the audio signal on INPUT CHA or INPUT CHB is distributed to all outputs (CH1 to CH8, mono operation).
Connections and operating elements 6 Indicator LED SIGNAL CHB This LED lights up when channel B receives an audio signal with a level above 40 mV. 7 CH5 – CH8 Level control for channels 5 to 8. Use these controls to adjust the output signal channel-related in a range of 0 to +6 dB.
