Karakteristike proizvoda
- 7-pojasni ekvilajzer: Independent frequency band control (64Hz/125Hz/250Hz/500Hz/2KHz/4KHz/8KHz) with a range of -6dB to +6dB. Allows precise adjustment of treble, midrange, and bass to compensate for speaker characteristics and room acoustics.
- Balanced XLR Preampdizalica: Supports both XLR and RCA inputs and outputs. Delivers high-quality audio to amplifiers or active speakers with excellent channel separation, resolution, soundstage, and a clean background.
- Bypass Design & High Performance: Features a bypass mode that can be activated by turning off the power, allowing for the enjoyment of the original audio signal without equalization. The T7 boasts a Signal-to-Noise Ratio (SNR) exceeding 104dB, a frequency response range of 20Hz-20kHz, and a distortion level as low as 0.003%, ensuring accurate audio reproduction.
- Attractive and Robust Design: Housed in a black aluminum alloy chassis, providing effective shielding, a cool aesthetic, and durable construction. Ideal for audiophiles seeking high-fidelity sound.
- Pogodne karakteristike: Operates without a volume control, outputting a predetermined level. Both XLR and RCA outputs function simultaneously.

Prednja ploča

This image shows the front panel of the Douk Audio T7, highlighting the input selector knob (RCA/BAL/OFF) and the seven equalizer adjustment knobs for 64Hz, 125Hz, 250Hz, 500Hz, 2KHz, 4KHz, and 8KHz.
The front panel features the following controls:
- Input Selector Knob (RCA/BAL/OFF): Selects between RCA input, Balanced (XLR) input, or activates bypass mode (OFF).
- Dugme za podešavanje 64Hz: Podešava pojačanje za frekvencijski opseg od 64 Hz.
- Dugme za podešavanje 125Hz: Podešava pojačanje za frekvencijski opseg od 125 Hz.
- Dugme za podešavanje 250Hz: Podešava pojačanje za frekvencijski opseg od 250 Hz.
- Dugme za podešavanje 500Hz: Podešava pojačanje za frekvencijski opseg od 500 Hz.
- Dugme za podešavanje 2KHz: Podešava pojačanje za frekvencijski opseg od 2 kHz.
- Dugme za podešavanje 4KHz: Podešava pojačanje za frekvencijski opseg od 4 kHz.
- Dugme za podešavanje 8KHz: Podešava pojačanje za frekvencijski opseg od 8 kHz.
Zadnja ploča

This image illustrates the rear panel connections of the Douk Audio T7, showing the Balanced XLR/RCA inputs, Balanced XLR/RCA outputs, and the DC 12V power input.
Zadnja ploča pruža sljedeće priključke:
- Balansirani XLR ulaz (L/R): For connecting balanced audio sources using XLR cables.
- RCA ulaz (L/R): For connecting unbalanced audio sources using RCA cables.
- Balansirani XLR izlaz (L/R): Za povezivanje na amplifiers or active speakers using XLR cables.
- RCA izlaz (L/R): Za povezivanje na amplifiers or active speakers using RCA cables.
- DC 12V IN: Power input for the included 12V DC adapter.
Vodič za postavljanje
1. Priključak za napajanje
Connect the included DC 12V power adapter to the "DC 12V IN" port on the rear panel of the T7. Plug the adapter into a suitable power outlet.
2. Audio ulazna veza
Za RCA ulaz: Connect your audio source (e.g., CD player, DAC, phone, tablet PC, TV set-top box, laptop) to the "RCA Input" jacks on the rear panel using RCA cables.
Za balansirani XLR ulaz: Connect your audio source to the "Balanced XLR Input" jacks on the rear panel using XLR cables.
3. Priključak audio izlaza
Connect the "RCA Output" jacks or "Balanced XLR Output" jacks on the rear panel of the T7 to your amplifier or active speakers using appropriate RCA or XLR cables. Both outputs can be used simultaneously.
4. Početno uključivanje
Ensure all connections are secure. Turn on your audio source and amplifier/active speakers. Then, power on the Douk Audio T7.
Uputstvo za upotrebu
1. Odabir načina unosa
Use the input selector knob on the front panel to choose your desired input: "RCA" for RCA sources, or "BAL" for Balanced XLR sources.
2. Adjusting Equalization
Once an input is selected, use the seven frequency adjustment knobs (64Hz, 125Hz, 250Hz, 500Hz, 2KHz, 4KHz, 8KHz) to fine-tune the audio frequencies. Rotate the knobs clockwise to boost the frequency band (+6dB) and counter-clockwise to cut the frequency band (-6dB).
Experiment with different settings to achieve your preferred sound profile or to correct room acoustics and speaker response.
3. Režim zaobilaženja
To listen to the original, unequlized audio signal, set the input selector knob to "OFF". This activates the bypass mode, allowing the audio signal to pass through the unit without any equalization.
4. Simultaneous Outputs
The T7 outputs audio simultaneously through both the RCA and Balanced XLR output ports. You can connect to multiple devices if needed.
Održavanje
Čišćenje
Wipe the unit with a soft, dry cloth. Do not use any liquid cleaners or solvents, as they may damage the finish or internal components.
Skladištenje
If the unit will not be used for an extended period, disconnect it from the power supply and store it in a cool, dry place.
Ventilacija
Ensure that the ventilation openings are not blocked to prevent overheating. Maintain adequate space around the unit for proper airflow.
Rješavanje problema
Nema izlaza zvuka
- Provjerite snagu: Ensure the power adapter is securely connected to the T7 and a working power outlet.
- Check Input Selection: Verify that the input selector knob on the front panel is set to the correct input (RCA or BAL), not "OFF" (bypass mode).
- Provjerite veze: Ensure all audio cables (input and output) are securely connected to both the T7 and your source/ampLifier/zvučnici.
- Check Source/Ampdizalica: Confirm that your audio source is playing and your amplifier/active speakers are powered on and functioning correctly.
Distorted Sound
- Check Gain Levels: Ensure that the equalizer knobs are not set to extreme boost levels, which can cause clipping or distortion. Try reducing the gain on specific frequency bands.
- Provjerite kablove: Pregledajte audio kablove na oštećenja ili labave spojeve.
- Kvalitet izvora: Verify the quality of the audio source. Poor quality source material can result in distorted output.
Brujanje ili šum
- petlja uzemljenja: A hum can sometimes indicate a ground loop. Try connecting all audio equipment to the same power strip or outlet. If the issue persists, a ground loop isolator may be necessary.
- Kvalitet kabla: Koristite visokokvalitetne, zaštićene audio kablove.
- smetnje: Držite uređaj dalje od drugih elektronskih uređaja koji mogu uzrokovati interferenciju.
