Operation
A
fter following the procedures outlined in the Installation/Rear Panel
Power Connections and Signal Connections sections, the Amplifier can be
turned on by pressing the FRONT PANEL STANDBY/POWER button. Allow
approximately twenty (20) minutes for the amplifier to reach operating
temperature and maximum performance potential. A short warm-up time is
dependent upon the amplifier being plugged in to an active AC mains
power source for at least two hours prior to activating the FRONT PANEL
STANDBY/POWER button. Therefore, it is recommended that the Amplifier
be continuously connected to an active AC mains power source.
If you desire to disconnect the AC mains for an extended period of time,
simply disconnect the AC power cable from the wall outlet and reconnect
upon your return. Slight transients may be heard in the loudspeakers during
the AC mains connect/disconnect transitions.
Your new Model 8T/Ti Amplifier will require an initial break-in period of at
least eighty (80) hours before maximum performance can be expected.
Efficient break-in procedures require the Amplifier to be fully operational
(playing music). Continuous and noticeable performance improvements will
occur during subsequent months of operation.
The Model 8T/Ti is provided with a user-selectable input impedance switch.
Under normal operating conditions, the high input impedance option should
be used. Always use the high input impedance option when tube type
preamplifiers, high impedance, or capacitor coupled signal sources are
connected to the Model 8T/Ti input jacks.
The low impedance input jacks may be used when the signal source is direct
coupled and capable of driving a low (600 ohm) impedance. There may be
noticeable sonic benefits when a low impedance configuration is used due to
the electrical termination of the interconnect cable. The results will vary due
to variables in interconnect cable characteristics such as impedance,
geometry, construction materials, etc. However, the final judgement of
musicality must be empirically determined when using this feature within the
conditions defined above.
Due to different sensitivities of associated equipment used with the Model
8T/Ti, the OVERALL GAIN switch can be used to optimize the total gain
structure of the entire system. This allows the volume control of your
preamp to be used in an ideal mid-range position.
