1 pav. Bendra view of the TDP-1 Direct Box. This image shows the compact black aluminum casing with the silver front and rear panels visible. The front panel features the XLR output and ground lift switch, while the rear panel displays the 1/4" input and thru jacks, along with the -15dB pad switch.

Figure 2: Output Panel. This close-up view highlights the XLR output connector and the Ground Lift switch. The XLR output is a standard 3-pin male connector for balanced audio signals. The Ground Lift switch helps to break ground loops, reducing hum and noise.

Figure 3: Input Panel. This image shows the 1/4" Input jack, the 1/4" Thru jack, and the -15dB Pad switch. The Input jack is where the instrument signal is connected. The Thru jack allows the signal to pass directly to an amplifier or other device. The -15dB Pad switch attenuates the input signal by 15 decibels, useful for high-output sources.

Valdikliai ir jungtys:

• INPUT (1/4" Jack): Connect your instrument (e.g., guitar, bass, keyboard) here using a standard 1/4" TS cable.
• THRU (1/4" Jack): This jack provides a direct, unprocessed copy of the input signal. Use it to send your instrument's signal to an amplifier or monitor without affecting the signal sent to the XLR output.
• -15dB PAD Switch: Engages a 15dB attenuation pad on the input signal. Use this when connecting high-output sources (e.g., active bass guitars, keyboards) to prevent signal clipping or distortion.
• OUTPUT (XLR Male): This is the balanced, low-impedance output. Connect this to a microphone preamplifier on a mixing console or audio interface using a standard XLR cable.
• ŽEMĖS KĖLIMO jungiklis: Disconnects the ground connection between the input and output. Use this switch to eliminate hum or buzz caused by ground loops between connected equipment. Flip the switch to the position that yields the quietest operation.

4. Sąranka

Follow these steps to properly set up your TDP-1 Direct Box:

1. Prietaiso prijungimas: Plug your instrument (e.g., electric guitar, bass, keyboard) into the ĮVESTIS 1/4" jack on the TDP-1 using a high-quality instrument cable.
2. Prisijunkite prie Amplifier/Monitor (Optional): If you wish to send your instrument's signal to an amplifier or stage monitor, connect a 1/4" cable from the THRU jack on the TDP-1 to the input of your amplifier or monitor.
3. Connect to Mixer/Interface: Prijunkite XLR kabelį nuo IŠVADA XLR connector on the TDP-1 to a microphone input on your mixing console, audio interface, or preampgyvesnis.
4. Set Pad Switch: If your instrument has a very high output level (e.g., active pickups, high-gain keyboards), engage the -15dB PAD switch to prevent input clipping. If the signal is clean without the pad, leave it disengaged.
5. Check Ground Lift: If you hear a hum or buzz after connecting all equipment, toggle the ŽEMĖS KELIMAS switch. Select the position that minimizes or eliminates the noise.
6. Sureguliuokite lygius: Once connected, gradually increase the gain on your mixing console or audio interface until you achieve an appropriate signal level.

5. Naudojimo instrukcijos

The TDP-1 is a passive device, meaning it does not require external power and operates by converting the signal impedance. Its operation is straightforward:

• Signalo konvertavimas: The primary function of the TDP-1 is to convert a high-impedance, unbalanced signal (from an instrument) into a low-impedance, balanced signal (for a mixer). This allows for long cable runs without significant signal loss or noise interference.
• Naudojant padėklą: If your instrument's output is strong and causes distortion or clipping at the mixer's input, activate the -15dB pad switch. This reduces the signal level before it enters the transformer, providing a cleaner signal to the mixer.
• Ground Loop Elimination: If you encounter a persistent hum or buzz in your audio system, it is often due to a ground loop. The Ground Lift switch isolates the ground connection between your instrument and the mixer, which can effectively eliminate this noise. Experiment with both positions of the switch to find the quietest setting.
• Per išvestį: The Thru output is useful for live performance or studio monitoring. It allows you to send your instrument's signal directly to your stage amplifier or a dedicated monitor system while simultaneously sending the balanced DI signal to the front-of-house mixer or recording interface.

6. Priežiūra

The TDP-1 is designed for durability and requires minimal maintenance.

• Valymas: Nuvalykite įrenginį minkštu, sausu skudurėliu. Nenaudokite abrazyvinių valiklių ar tirpiklių.
• Saugykla: Nenaudojamą prietaisą laikykite vėsioje, sausoje vietoje, apsaugotoje nuo tiesioginių saulės spindulių ir ekstremalių temperatūrų.
• Patikra: Periodically check cables and connectors for wear or damage. Replace any faulty cables immediately.
• Aptarnavimas: Nebandykite patys atlikti įrenginio techninės priežiūros. Visus techninės priežiūros darbus patikėkite kvalifikuotiems techninės priežiūros darbuotojams.
