UNPACKING
Before unpacking, check if there is any damage to the carton. Place on a flat
surface with the arrow upward. Carefully remove your new amplifier and all
accessories from its packing carton, and examine it closely for signs of shipping
damage. Carefully remove the transparent protective film protecting the mirror
finish stainless steel body. Insure that the tubes are correctly inserted in their
sockets. Make sure that your amplifier came packed with the following items:
- Power supply cord - USB Cable - Toslink Optical w/Mac Plug - Remote Control
- Tube Cover Removal Wrench - White Gloves - Safety Instruction
SPEAKER CONNECTION
Make sure that all connections between this unit and other components are
made correctly, that is to say L (Left) to L, R (Right) to R, + to + and - to -
Connect using high quality, bare (stripped) speaker wire or banana plugs. Please
note that if your speaker wires are not connected properly you may hear no
sound or if polarities are reversed, you will hear oddities in the signal path with
an unnatural loss of bass frequencies. DO NOT POWER ON UNIT WITHOUT
SPEAKERS CONNECTED
When connecting speakers, ensure they have an impedance of between 4 & 8
ohms, which are most speakers.
Make sure the wire holders are firmly screwed in to prevent wires from becoming
loose. If wires touch, the speakers and or the unit could be damaged.
COMPUTER CONNECTION
If you plan to use the amplifier with your computer, connect the USB cable
supplied with the unit from your computer to the USB input on the back of the
amplifier.
POWER CORD
Connect the power cord: first be sure to set the "VOLUME" control to the lowest
position and the power switch in the “OFF” position. Then connect the power
cord into the power socket on the rear panel of the amplifier. Next, connect the
other end of the power cord into the outlet. The power outlet, which the
amplifier power cord is connected to, must be the 3-pin grounding type. Check
again to make sure both speakers are properly connected and the voltage
selector switch (located on the bottom of the amplifier if installed on the unit) is
properly set before turning power “ON”.
POWER ON
Your new amplifier is ready for operation after the speakers, power cord, signal
or USB cables have been properly installed. When you are sure the connections
are correct, adjust the “VOLUME" to the minimum and push the power button
located on the center of the front panel to the “ON” position. Observe that the
Blue LED and all vacuum tubes are lit. The slow power up protects you
components. The amp will be ready to play in about 15 seconds.
NOTICE: The sound quality will be affected by all the elements of the audio
chain: recording, recorded medium, source, amplifier, speakers and room. We
therefore recommend that you select quality inputs and quality speakers to
perform with the neuhaus laboratories T-2 amplifier.
COMPUTER AUDIO: USE OF THE WITH USB PORT on the neuhaus
laboratories T-2 amp.
WINDOWS OPERATING SYSTEMS
WINDOWS COMPATIBLE
When your computer is “ON”, you will find a new USB device in the “Device
Manager” (Windows XP): USB Speakers. The amplifier is designed for “Plug &
Play" set up and in most cases the audio signal from your computer should play
through the amplifier without requiring any additional adjustment. If the audio
from your computer cannot be heard through the amplifier and you are using
Windows XP, first click on the "speaker" icon at the bottom right corner of your
screen and adjust the sound output to the maximum position. If you still cannot
hear your computer: go to the Windows “Control Panel” and select "Sounds and
Audio Devices" (XP) or "Multimedia" (98SE, ME, 200). Under the "Audio" tab,
choose C-Media USB Audio for "Sound Playback”. Your PC sound will now play
through your neuhaus laboratories T-2 tube amplifier. The sound level can
be adjusted from the “speaker bar” on your computer and should be placed at
maximum so main volume is controlled by the T-2 amp.
MAC OPERATING SYSTEMS
MAC COMPATIBLE
Plug the USB cable into the USB port of your Mac computer. Select “Sound” in
System Preferences. Under the “Output” tab, select “C-Media USB Audio”.
Your Mac's sound will now play through your neuhaus laboratories T-2 tube
amplifier.
OPTICAL SYSTEM CONNECTION
Most Apple Mac computers allow optical connection directly from the
computer to the neuhaus laboratories T-2 amplifier. Optical cable, included
(Toslink cable with Mini Headphone plug adapter). Plug the square toslink
connector to the rear of the amplifier and the plug connection to the mini
headphone port of the Mac. Push plug all the way in. This optical connection
bypasses the MAC Digital to Analog Converter (DAC). Under System Preferences,
Sound, Output should read Digital Out. Your Mac's sound will now play through
your neuhaus laboratories T-2 tube amplifier.
APPLE AIRPORT EXPRESS CONNECTION
Send your ITunes music wireless from your computer to the neuhaus
laboratories T-2 amplifier. Apple Airport Express allows you to connect the
neuhaus laboratories T-2 directly from the Airport Express Toslink connection
to an Apple Mac or Windows Computer with optical or Toslink connection. Please
refer to the Apple Airport Express Operating Manual.

HEADPHONE USE, REAR SPEAKERS MUST BE CONNECTED.
BURN-IN
While the amplifier should sound fine straight out of the box, you may notice
that your amplifier needs a period of “burn-in" before it sounds optimal. Your
unit should be considered adequately burned-in after the first 50 hours of use.
TUBE BIASING
The neuhaus laboratories T-2 is self-biasing; there is no need to adjust the
bias of the tubes.
NEVER REMOVE THE TUBES WHILE THE UNIT IS IN OPERATION.
SERVICING
The user should not attempt to service this product beyond that described in the
operating instructions. All other servicing should be referred to qualified service
personnel or neuhaus laboratories.
DAMAGE REQUIRING SERVICE
This product should be serviced by qualified service personnel when:
- objects have fallen, or liquid has been spilled into the unit;
- the component has been exposed to rain or moisture;
- the amplifier does not appear to operate normally or exhibits a marked change
in performance;
- the amplifier has been dropped, or the enclosure damaged;
- the unit will not turn “ON” or will not produce sound in one or both channels
- there is distortion in the sound reproduction.
TUBES
Tubes last a long time. The smaller pre-amp tubes can last anywhere from
10,000 to 100,000 hours. Larger power and driver tubes usually last 5,000 hours.
At 2 hours per day use, 5,000 hours = 7 years.
The vacuum tubes used on the neuhaus laboratories T-2 amplifier come preinstalled and should provide many years of performance. Check to insure tubes
are properly seated. Replacement tubes can be purchased from the neuhaus
laboratories website. Tubes MUST be placed in the correct socket. Incorrect
placement can damage the tubes and amplifier.
