Safety • Check for correct mains voltage and condition of IEC lead before connecting to power outlet • Use double insulated speaker wire with adequate current rating for 100V speaker connections • Do not use 4-16Ω and 100V terminals at the same time • Do not connect 8Ω speakers to the 100V terminal or 100V speakers to the 8Ω terminal • Do not allow any foreign objects to enter the case or through the ventilation grilles Placement • Keep out of direct sunlight and away from heat sources • Keep away from damp or dusty environments • For rack-mounting, use an appropriate shelf unit (e.g. 853.055UK) and ensure adequate support • Ensure adequate air-flow and do not cover cooling vents at the front and rear of the amplifier • Ensure adequate access to controls and connections Cleaning • Use a soft cloth with a neutral detergent to clean the casing as required • Use a vacuum cleaner to clear ventilation grilles of any dust or debris build-ups • Do not use strong solvents for cleaning the unit 953.108UK, 953.109UK User Manual Front panel Rear panel Connection and setup Connect the rear IEC inlet (17) to the mains using the supplied mains lead (or an equivalent approved type). Ensure that the mains voltage is correct and that the mains outlet is switched on. Connect any line level audio inputs to the Aux input (12) on the rear panel using RCA leads. Connect a microphone (if required) to the front panel jack input (10). Further amplifiers can be connected from the rear Out RCA sockets (11). The DM series amplifiers can be used either with 100V line or standard low impedance speakers. These 2 configurations cannot be used together, so it is important to decide which method will be used at the start. Speaker connections are provided as spring terminals on the rear panel (13, 14, 15) Wiring is described for each type of speaker system on the following page. Next to the speaker connections is a spring terminal for FM Antenna (16) This should be connected to the core of an antenna cable for good FM radio reception (if required) NOTE: Do not connect a speaker output to the antenna by mistake. This may carry high voltage. 1. Power on/off switch 2. Media player display 3. USB media port 4. Media player mode & transport controls 5. Treble EQ 6. Bass EQ 7. Media player level 8.
