Thank you for choosing TUBE DRIVER. Tube Drivers musicality and absolute sonic transparency allow accurate reproduction of recorded music enabling you to hear as well as feel the music the way the artist intended. These handcrafted amplifiers feature full differential “front ends” based upon a true instrumentation amplifier topology. Tube Drivers utilize only the highest quality Svetlana tubes in our unique configurations.
The TD2200PRO and TD225A amplifiers represent a radical new approach to mobile audio. All voltage gain stages are completely vacuum tube-10 tubes in all! Other than the output devices themselves, there are no solid state devices in the audio path. Specific types of Svetlana tubes were chosen for their application in the audio section. 6N1P tubes were chosen for their high gain. 6SN7 tubes are ideal as cathode followers at the output of the preamp increasing current capability.

Warning! To prevent a short to ground, disconnect the negative (-) terminal of the system’s battery before you begin. If the power cable shorts to ground, current will continue to flow until the short is opened, the main fuse blows, the battery explodes, or the wire melts.

Speaker Connections Follow these simple instructions and refer to the diagram below to make your speaker connections: • Using at least 16 gauge wire, run wire from the speakers to the amplifier(s) using the same precautions that you followed for running the power, ground, and remote wires • Cut off excess wire • Use wire strippers to strip 1/4 inch of insulation at the end of the wires • Attach the speaker wires to the amplifier’s POWERLOCK connector and plug it in Speaker PowerLock Connector Right Speake
Bridging All multi-channel T UBE DRIV E RS are capable of being bridged into a 4Ohm mono output without switches or bridging modules. You can achieve this mono channel by using the left positive (+) speaker connection and the right negative (-) speaker connection. (Refer to the end panel drawing on the next page.) Note: Total bridged impedance of less than 4-ohms may trigger the protection circuitry causing reduced output and may eventually damage your amplifier.
Input Jacks Your TUBE DRIVER includes both RCA and Mini-DIN (balanced) inputs. The supplied RCA connections allow you to use TUBE DRIVER with other brands of audio gear. Our Differential RCA inputs provide a dramatic improvement in noise reduction over standard RCA input types. Our fully balanced Mini-DIN connection system features high signal voltage capability and the highest possible sound quality. A single cable for 2 channels also simplifies installation.
Input Gain Control There is an Input Gain Control located on the end panel under the RCA input jacks. This is not a volume control! This control matches the output signal voltage of the source unit to the amplifier inputs. By turning the control clockwise (to the right), the inputs of the amplifier become more sensitive and will allow a weak signal of approximately 1/2 volt to drive the amplifier to full power.
Power Side 1. POWER A red light indicates that the amplifiier is turned on (After warm-up sequence). 2. WARM UP A red light indicated that the tubes are warming up. (Refer to Pg. 4; Remote Turn-on) 3. POWER / GROUND After you have securely connected your power and ground wires, plug in the connector here.
Input/Control Side 1. SPEAKER OUTPUTS/REMOTE(Turn on) After connecting remote and speaker wires plug in the connector here. 2. GAIN CONTROL Use this control to match the output level of the head unit to the outputs of the amplifier 3. BALANCED INPUT Plug in the mini-din output from the LDX-33 crossover, LD-3 line driver, or other balanced source here. 4. -12dB For use with high level inputs (4V up to 12V). Push this switch in to attenuate the input by 12dB.
No Sound Is the WARM UP LED illuminated? YES NO Do you have 12V at the amplifier’s connections? The warm up cycle can take up to 40 sec., Is there sound after that? YES YES NO Is there signal on the RCA’s? NO Does the amp remote (REM) have 12V? You’re done YES YES Contact your dealer Check main system fuse. Did that work? YES You’re done Check all connections. Repair as needed NO Trace back the amp remote to your source unit.
No Sound in One Channel Check the pre-amp (RCA/Mini-Din) cables for open connections and make corrections. Did you find open connections? NO YES You’re done Reverse the left and right inputs. SOUND IS NOW IN... Opposite Channel Same Channel Problem is further up the signal path. Reconnect RCA’s to amp as normal. Reverse RCA inputs at crossover. Problem is in the speaker or speaker wire of the silent channel. Check speaker leads for pinched, shorted, or open connections. SOUND IS NOW IN...
Noises While the Engine is On Alternator whine: This noise changes in frequency with engine RPM. Check for: . Excessive input level . High resistance in cabling or corroded and/or loose connections . Polarity of the input cables If the problem persists, check the whines and pops checklist below. Ticks/buzz: This noise should go faster and slower with engine RPM, but not really change in frequency. This is due to the ignition or the fuel pump. .
Noises While the Engine is On or Off System hiss: System hiss is a white noise that occurs even when the engine is off. It is usually due to excessively high gain settings. If the hiss is still audible when you disconnect the input cables from the amplifier, check the input level on the amplifier. If the hiss disappears when you remove the input cable, it may be a poor quality source unit, components between the amplifier and the source unit, or poor level settings.
