ABOUT THX
®
THX
®
and THX Ultra2
™
THX is an exclusive set of standards and technologies established by the
world-renowned film production company, Lucasfilm Ltd. THX grew from
George Lucas' personal desire to make your experience of the film
soundtrack, in both movie theaters and in your home theater, as faithful as
possible to the master recording. Before any home theater component can be
THX Ultra2 certified, it must pass a rigorous series of quality and performance
tests. Only then can a product feature the THX Ultra2 logo, which is your
guarantee that the Home Theater products you purchase will give you superb
performance for many years to come.
Home THX Amplifiers
With today's superior quality, but exceptionally complex audio systems, it is
important to ensure that noise, distortion and frequency response errors are
negligible in all links in the audio chain. With modern discrete multichannel
sources it is especially important that maximum power is instantly available
without instability, rise in distortion or other undesirable side effects. THX
Ultra2 requirements cover every performance aspect of this product including
operation, output power levels, gain, frequency response and numerous other
parameters. Whether you choose music or movies, multichannel or stereo, this
amplifier will be supremely flexible, easy to use, sonically transparent and
absolutely reliable.
CONTROLS AND FUNCTIONS
Power Switch
This rocker switch turns the AC power ON (depressed top) and OFF
(depressed bottom).
Power Indicator
This LED will illuminate when the 2000 series amplifier is powered ON.
RCA Input Jack
Gold-plated RCA input jacks are provided for each channel to connect to the
output jack of the corresponding preamplifier channel.
Five-way Binding Post Speaker Output
Five way binding posts are provided for each channel to connect to the
corresponding loudspeaker. The red connection corresponds to the positive
(+) input of the loudspeaker, and the black connection corresponds to the
negative (–) input of the loudspeaker.
Dimmer Switch
The three-position switch controls the intensity of the blue cascade panel
illumination. FULL brightness is all the way to the right; OFF is in the center;
and DIM is all the way to the left. The power switch must be ON for
illumination.
A/C Power Connection
This three-prong receptacle is the A/C power connection, utilizing a standard
IEC connector.
A/C Fuse Holder
This contains the primary A/C fuse. Replace only with the same value and
rating as specified on the back of the amp.
SYSTEM SETUP
1. Input Connections
With the amplifier turned off, connect shielded RCA cables between the
preamplifier outputs and the corresponding amplifier inputs. Due to the
internal architecture of the amplifier, it is important that you follow the
naming conventions on the rear panel. (For example, for proper operation,
the "Left Surround" and "Right Surround" outputs of the preamplifier should
be connected to "Surround Left" and "Surround Right" inputs of the
amplifier.)
2. Output Connections
With the amplifier turned off, connect speaker wire between the amplifier’s
speaker output terminal and the loudspeaker’s corresponding input terminal.
The red connector refers to the positive (+) speaker connection, and the
black connector refers to the negative (–) speaker connection. For proper
operation, be sure to connect the loudspeaker to the correct amp output.
NOTE:
Use only insulated speaker wire of an appropriate gauge for all
connections making sure that no bare wires touch each other. Use of
uninsulated wiring, or conditions where bare wires are touching could result
in an electrical short leading to possible risk of electrical shock, equipment
failure or the risk of fire.
3. Power Connection
Plug the A/C power cord into the back of your 2000 series amplifier, and
then into the A/C wall outlet.
TROUBLESHOOTING
No Sound
1. Ensure the A/C power cord is fully seated.
2. With the amplifier unplugged, check that the A/C fuse is not blown.
3. Check all power connections.
4. Verify proper connection of inputs and outputs.
5. Check for shorted positive (+) and negative (–) connections.
6. If the preamplifier is working properly, the power light is on, and there is still
no output from one or more channels, the likelihood is that there is a blown
internal fuse. Contact the dealer from whom you purchased the amplifier, as
they should be able to check and change the fuse for you. Do not attempt
to change this fuse yourself: Unauthorized repairs will void your warranty.
Amplifier Hum
The 2000 Series amplifiers utilize a large toroidal transformer, so some
physical hum can be expected. A hum that is heard when you step away from
the amplifier could be considered unusual, but does not necessarily indicate a
problem with the amplifier. Contact your dealer if you have any concerns about
amplifier hum. Hooking the amplifier up at the dealer’s store and comparing it
with the floor model is a good way to verify whether or not what you are
experiencing is normal.
1. Plug the amplifier into different outlets (different circuits) in the house to see
if it exhibits the same hum.
