Contact your TASCAM dealer or distributor if any of
these items is missing.
Physical installation
The unit can be fitted in any standard 19" rack, using
the mounting kit (screws and washers) provided. No
rear support is needed.
3U of rack space is required for the unit itself. Since
the AV-452 incorporates power amplifiers, it is
strongly recommended that at least 1U of space is
left above the unit to avoid overheating.
NOTE
Do not install this apparatus in a confined space such as
a book case or similar unit.
For the same reason, adequate space for ventilation
should be left at the front and rear of the unit. In any
case, the space at the rear of the unit should be suffi-
cient to accommodate the audio and video connec-
tors plugged into the AV-452.
Since many of the functions of the unit are set using
small preset controls (trimmer pots, DIP switches,
etc.) on the rear panel, we suggest that you ensure
you have clear visual access to the rear panel, or that
you make these settings before final installation in
the rack.
Power supply
The AV-452 can use an AC power supply as marked
on the rear panel. Do not use any other voltage of
power supply, as this may result in damage.
The unit should be properly grounded (earthed).
The power switch is located on the rear panel to pre-
vent the user from accidentally turning power off
during a presentation. If you want to turn the system
on and off routinely, you may consider using a power
switch for the outlets, or using a centrally-switched
power distribution system.
