Ventilation Requirements
Important: Position the GT series in a way that
ensures good airflow. Make sure its vents on the
top
and
sides
are
ventilation is crucial for its operation. Avoid
placing it in areas with excessive dust or allowing
dust to accumulate and clog the vents. Do not
place the GT series directly above or below any
device that generates heat, such as an audio
amplifier.
Ensure there is a minimum of 2 inches of open
space around the sides of the unit, with free airflow
above it. Maintain a clearance of approximately 1.5
inches above and below the unit, especially if it's
mounted in a rack.
Installation
The GT series can either be mounted on a wall or
placed on a shelf within the rack.
Electrical Power
The GT series operates on 24VDC, and its adapter
is compatible with 110-230VAC, 50/60 Hz. For the
best performance, connect it and any related
equipment to a dedicated 20-amp circuit. To
reduce interference from electrical noise, consider
using a power line conditioner.
Important Considerations
Always disconnect the power cord before
making any connections.
Ensure all connections are correct and the
wiring polarity is accurate.
Keep power cords away from signal cables to
avoid interference.
Use high-quality signal cables and patch cords.
Label all wires clearly at both ends, indicating
their room location.
Avoid placing speaker or signal cables near
electrical wires. If they must run parallel, keep
them at least two feet apart. Cross electrical
lines at a 90° angle.
Do not connect the main power cord until all
other connections are verified. Connecting or
disconnecting wiring while the system is on can
cause damage or erratic performance. Touching
live wiring can lead to electrical shock.
