Page 7: Safety Instructions
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. D3400... - Page 8 Safety instructions DANGER! Electric shock caused by high voltages inside Within the device there are areas where high voltages may be present. Never remove any covers. There are no user-serviceable parts inside. DANGER! Electric shock caused by short-circuit Always use proper ready-made insulated mains cabling (power cord) with a pro‐ tective contact plug.
- Page 9 NOTICE! Risk of fire Do not block areas of ventilation. Do not install the device near any direct heat source. Keep the device away from naked flames. D3400...
- Page 10 Safety instructions 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. 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.

- Page 18 Connectors and operating elements "Fault" LEDs (2) These LEDs light up for 3 seconds after the unit is switched on. After that the unit is ready for use. If these LEDs light up during operation, the protection circuit is activated in the respective channel.
- Page 19 –14 should be avoided in practice, because then the amp is not working in the optimum dynamic range (headroom). "Power" LEDs (6) These LEDs light up, when the unit is switched on. If they are not lit, although the power switch is in ON position, check the voltage supply. D3400...
- Page 20 Connectors and operating elements "Thermal" LED (7) This LED lights up, when the internal temperature is too high. Then an automatic protection circuit reduces the output power. If the temperature keeps rising, the amp will automatically power down. In this case the "Fault" LEDs (2) light up. Speaker outputs left/right (8) Mounting socket for lockable speakON connectors.
