Installation

L
ocate the Amplifier as close as possible to its final installation point. Allow
access to the rear panel for making connections.
The Model 8T/Ti Amplifier is convection cooled, eliminating the need for
fan or forced air cooling. When operating, the chassis should have at least
two (2) inches of air space around the heatsink areas. Multiple chassis can
be stacked vertically thus facilitating an upward flow of warm air currents
throughout the vertical heatsink fin areas. This upward flow must not be
impeded or recirculated around the chassis if proper cooling is to be
maintained.
Supplied with your Model 8T/Ti Amplifier are two different support systems.
An assessment of the supporting structure should be made to determine the
proper system for the Amplifier. Both spiked and compliant interface
supports can be easily installed within the indentations on each of the four
chassis pods located underneath the corners of the chassis. These system
options permit the coupling or decoupling of the Amplifier chassis to the
supporting structure.
As a general rule, most installations allow the Amplifier chassis to be rigidly
coupled to the supporting structure via the spiked coupling interface
supports. In carpeted installations, these supports provide excellent coupling
from the Amplifier chassis to the rigid supporting structure below. In
installations where the integrity of the supporting structure is poor, the
Amplifier chassis can be loosely coupled to the supporting structure via the
compliant isolation interface supports. This will help attenuate the transfer
of spurious energy from the supporting structure into the Amplifier chassis.
Note: Another installation option, when incorporating the Battery Power
Supply, utilizes its chassis as a stable, high mass structural support for the
Amplifier chassis. In this configuration, the Battery Power Supply chassis is
rigidly coupled to the supporting structure via the spiked coupling interface
supports and the Amplifier is placed directly above the Battery Power
Supply and isolated via the compliant isolation interface supports.
If desired, a coin may be placed directly under the point of the spiked
coupling support to prevent damage to various surfaces (i.e. hardwood
floors).

Please strictly follow the steps in order as outlined below
Important:
before operating your Model 8T/Ti Amplifier.
Verify that the AC MAINS CIRCUIT BREAKER and both RIGHT and
1
LEFT CHANNEL CIRCUIT BREAKERS are in the ON position (green
color visible).
Verify that the VOLTS AC INPUT identified on the rear panel
2
corresponds to the AC mains voltage of your service area.
Install the AC power cable between the Amplifier and an active AC
3
mains outlet.
Power Supply Jumpers. Do not remove unless used with the optional
4
BPS-8 Battery Power Supply. If removing, always use the knurled ring
to loosen and remove these jumpers and covers as one unit.
Note: If the Amplifier is moved to another location, simply disconnect the
AC power cable from the AC mains wall outlet. It is not recommended to
use the AC MAINS CIRCUIT BREAKER to remove or connect AC mains
power to the Amplifier.
