(1) POWER SWITCH

Use this switch to power unit ON or OFF. The integrated LED will light when the unit is ON. Before turning on this unit, verify connection to the proper voltage AC source, check all connections and turn down the level controls of equipment connected to the outputs.

(Note: The TMP-1 will not output audio for approximately 16 seconds after power up due to the time it takes for the tubes to warm up. Do not turn up the audio until after this warm up period to avoid possibly damaging speakers or your hearing due to improper level settings.)

(2) INPUT CONTROL

The INPUT CONTROL sets the amount of input gain of the TMP-1, turn the control clockwise to increase gain and counter- clockwise to decrease gain. You may control two ranges of gain with this control, +26 to +60dB and +6 to +40dB. Selection of the gain range is made with the +20dB GAIN SWITCH (3)

(3) +20dB GAIN/NORM SWITCH

Use the +20dB GAIN/NORM switch to set the gain range of the INPUT CONTROL (2). When the switch is out, the TMP-1 operates in Normal mode, depressing the switch adds 20dBs of gain. For microphone applications, where more level is needed, push the switch in.

(4) PHANTOM POWER SWITCH

Use the PHANTOM POWER to supply power to all microphones requiring +48V phantom power. The TMP-1 phantom power is engaged and disengaged with this switch Phantom power is applied to pins 2 and 3 of the XLR INPUT (13) jacks when this switch is pushed in. To disengage phantom power, position the switch in the out position.

(5) OUTPUT LEVEL VU METER

The output level of the TMP-1 can be monitored using the analog OUTPUT LEVEL VU METER. The meter’s 0dB marking repre- sents +12dB at the XLR output and +6dBu at the 1/4" output. The output meter will also reflect any attenuation due to the output limiter when it is engaged.

(6) CLIP/LIMIT LED

The CLIP/LIMIT LED lights green when the unit is powered. The LED also functions as a clipping and limiting indicator. The LED lights red when the audio signal reaches 6dB below hard clipping. If the OUTPUT LIMITER SWITCH (8) is depressed, the LED will light red when the limiter engages at which point the gain will be reduced automatically to avoid clipping.

(7) PHASE REVERSE / NORM SWITCH

When the switch is in the Out position of the output signal is normal. Depressing the switch reverses the phases of the output signal. In multi-microphone applications, mic placement can affect the phase of the signals. If your sound is “thin” or “out of position”, reverse the phase to correct the problem.

(8) OUTPUT LIMITER SWITCH

When this switch is depressed the output level is limited to 0dB for the 1/4 output and +6dB for the XLR output. This is specially designed to prevent clipping of the audio waveform. This also reduces the possibility of overload to any units connected to the outputs of the TMP-1.

(9) OUTPUT CONTROL

The OUTPUT CONTROL sets the output level of the TMP-1. When the control is fully counterclockwise the output level of the TMP-1 is zero. Turning the control clockwise increases the level of the output to a maximum of +10dB of gain. This gain is in addition to the existing input gain.

TMP-1 MICPREAMP specifications

The Nady Systems TMP-1 MICPREAMP stands out as a versatile and dependable microphone preamplifier designed for both studio and live sound applications. Its compact design and robust features make it an essential tool for audio professionals seeking high-quality sound capture and enhanced microphone performance.

At the heart of the TMP-1 is a high-performance preamp circuit that delivers an impressive gain range of up to 60 dB, allowing it to amplify even the quietest sound sources without introducing unwanted noise or distortion. This capability is especially beneficial for capturing delicate vocals or intricate musical nuances, ensuring clarity and fidelity in every recording.

One of the key features of the TMP-1 is its low self-noise floor, measured at just 6 dB, which enhances its performance in both quiet studio settings and dynamic live environments. This characteristic ensures that the audio captured is true to the original sound, making it ideal for professional audio applications. The TMP-1 also incorporates an input impedance of 2 kOhm, which provides optimal loading for most dynamic and condenser microphones, ensuring a rich and full frequency response.

The preamp is equipped with a switchable low-cut filter, allowing users to eliminate unwanted low-frequency noise and rumble. This feature is particularly useful when recording in less-than-ideal environments or when dealing with high-output sound sources. The low-cut filter can be easily engaged, giving users the flexibility they need to achieve the best sound possible.

Another notable aspect of the TMP-1 is its power supply versatility. It can operate on 48V phantom power, making it compatible with a wide range of condenser microphones. Additionally, its compact and robust design allows for easy mounting in rack systems, making it an ideal choice for mobile recording setups or permanent installations.

The overall build quality of the TMP-1 is commendable, with a durable chassis that can withstand the rigors of road use while maintaining its reliability in the studio. Its user-friendly interface includes intuitive gain and level controls, making it accessible for both seasoned audio engineers and beginners alike.

In summary, the Nady Systems TMP-1 MICPREAMP combines high-quality audio performance, versatility, and convenience in a compact unit. Its comprehensive features make it a solid choice for those looking to elevate their audio recordings and achieve professional sound quality in various environments.
