Location
• Install your DA Series Amplifier in well ventilated rack cabinets at a maximum height of 2 meters above the floor.
• Secure both front and rear brackets to the rack.
• Connect the AC Mains connector to a circuit breaker.
• Install the amplifier far from EMF emitting devices.
• Avoid placing the amplifier close to heat generating sources.
Cooling
Do not block the ventilation openings and allow a distance of at least 50 cm from the front and rear ventilation openings of
the amplifier. The DA Series implements a forced-air cooling system to maintain constant operating temperatures. Air enters
from the front panel and exits from the back of the amplifier. The cooling system features variable-speed DC fans controlled
by the heat sink mounted sensors. This ensures that fan noise and internal dust accumulation are kept to a minimum.
In the rare case of overheating, the amplifier is protected by limiting the output power to levels that can be sustained at the
actual ambient temperature. The DA Series amplifiers can be stacked one on top of the other, but it is recommended to leave
one rack unit empty every three amplifiers to guarantee adequate air flow.
Cleaning
Use a dry cloth for cleaning the chassis and the front panel. Air filter cleaning should be scheduled in accordance with the
dust levels in the amplifier’s operating environment. To remove the air filter, detach the front metal cover by unscrewing the
two T20 Torx screws (visual instructions shown below). Use compressed air to remove dust from the filter or wash it with
clean water (let it dry thoroughly before reinstalling).
AC Mains Supply
The DA Series amplifiers implement a universal switching mode power supply, with power factor correction operating in the
range from 100 VAC up to 240 VAC (±10%). AC mains connection can be found in the rear panel through the IEC C20 inlet.
The approved power cord is provided.
Signal Grounding
There is no ground lift switch or terminal on the DA Series amplifier. To minimise hum and/or interference entering the signal
path, always use balanced input connections. For safety, the unit MUST always operate with the electrical safety earth
connected.
