Product Overview
The TMP-1 features a robust design with intuitive controls for optimal audio processing.
This image shows an angled view of the DYNASTY PROAUDIO TMP-1 Professional Vacuum Tube Microphone Preamplifier. The front panel with controls and indicators is visible, along with the sturdy black casing.
This image provides a close-up view of the TMP-1's front panel. It clearly displays the "OUTPUT LEVEL" LED indicators, "Gain Input" and "Drive" rotary knobs, and push-buttons for "Phantom Power", "Limit", "Phase", and "Gain".
This image shows the rear panel of the TMP-1, highlighting the input and output connections. It includes XLR and 1/4-inch (6.35mm) input jacks, XLR and 1/4-inch (6.35mm) output jacks, and the AC 9V power input.
Front Panel Controls and Indicators
- OUTPUT LEVEL LEDs: Indicators for signal level (-10, -5, 0, +3, +6dB Peak).
- Gain Input Knob: Adjusts the input gain from minimum to maximum.
- Drive Knob: Controls the amount of tube saturation/drive.
- Phantom Power Button (ON/OFF): Activates/deactivates 48V phantom power for condenser microphones.
- Limit Button (ON/OFF): Engages/disengages the built-in limiter to prevent clipping.
- Phase Button (Reverse/Normal): Reverses the phase of the input signal.
- Gain Button (+20dB/Normal): Provides an additional +20dB gain boost.
Rear Panel Connections
- INPUT (XLR & 1/4-inch): Balanced XLR and unbalanced 1/4-inch (6.35mm) inputs for microphones or instruments.
- OUTPUT (XLR & 1/4-inch): Balanced XLR and unbalanced 1/4-inch (6.35mm) outputs for connecting to mixers, audio interfaces, or other audio devices.
- AC 9V: Power input for the included AC adapter.
Setup
- Power Connection: Connect the supplied AC 9V power adapter to the "AC 9V" input on the rear panel of the TMP-1, then plug the adapter into a suitable power outlet.
- Input Connection:
- For microphones: Connect your microphone to either the XLR or 1/4-inch INPUT jack on the rear panel.
- For instruments: Connect your instrument (e.g., guitar, bass) to the 1/4-inch INPUT jack.
- Output Connection: Connect the TMP-1's XLR or 1/4-inch OUTPUT to your mixer, audio interface, or recording device's input.
- Initial Settings: Before powering on, ensure the "Gain Input" and "Drive" knobs are set to their minimum positions. Ensure "Phantom Power" is OFF unless using a condenser microphone.

Operating Instructions
Powering On
Once all connections are made, power on the TMP-1. The "Power" LED on the front panel will illuminate.
Using Phantom Power
If you are using a condenser microphone, press the Phantom Power button to activate 48V phantom power. The corresponding LED will light up. Warning: Do not activate phantom power when using dynamic microphones or ribbon microphones, as this can cause damage.
Adjusting Input Gain
Slowly turn the Gain Input knob clockwise to increase the input signal level. Monitor the "OUTPUT LEVEL" LEDs. Aim for the signal to primarily light up the -5 and 0 dB LEDs during normal operation, with occasional peaks into the +3 dB LED. Avoid consistently hitting the +6dB Peak LED, which indicates clipping.
Applying Drive (Tube Saturation)
The Drive knob controls the amount of tube saturation. Turn it clockwise to add warmth and harmonic richness to your signal. Experiment with this control to find the desired sonic character.
Using the Limiter
Press the Limit button to engage the built-in limiter. This helps prevent signal peaks from exceeding a certain level, protecting your recording equipment from clipping and providing a more consistent output level.
Phase Reversal
The Phase button allows you to reverse the phase of the input signal. This can be useful in multi-microphone setups to correct phase cancellation issues or for creative effects.
Additional Gain Boost
If your input signal is very low, you can press the Gain button to apply an additional +20dB gain boost. Use this judiciously to avoid introducing unwanted noise or distortion.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the unit. Do not use liquid cleaners or solvents.
- Storage: Store the unit in a cool, dry place away from direct sunlight and extreme temperatures.
- Tube Replacement: The 12AX7 vacuum tube has a finite lifespan. If you notice a degradation in sound quality or increased noise over time, the tube may need replacement. This should be performed by qualified service personnel.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power adapter not connected; faulty outlet; faulty adapter. | Check power connections; try a different outlet; test adapter if possible. |
| No sound output | Incorrect cable connections; gain too low; phantom power not engaged for condenser mic; faulty cable. | Verify all input/output cables are securely connected; increase Gain Input; activate Phantom Power for condenser mics; try different cables. |
| Distorted sound | Gain too high (clipping); faulty tube; incorrect impedance. | Reduce Gain Input; check OUTPUT LEVEL LEDs for clipping; if distortion persists, consult service for tube inspection; ensure proper impedance matching. |
| Hum or noise | Ground loop; faulty cables; interference from other electronics. | Use balanced cables; try isolating power; move unit away from other electronic devices; check for faulty cables. |
