Упутства за подешавање

1. Распакивање и преглед

Пажљиво уклоните amplifier head from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. Retain the packaging for future transport or storage.

2. Tube Overview

The OA-H05 amplifier head utilizes three types of tubes for its operation:

• Преamp цев: 1 x 12AX7 (ECC83)
• Цев за напајање: 1 к ЕЛ84
• Rectifier Tube: 1 x 6Z4

3. Connecting to a Speaker Cabinet

Пре укључивања amplifier, ensure it is connected to a suitable speaker cabinet. The OA-H05 provides two output jacks:

• 8Ω (8 Ohm) Output: For speaker cabinets with an 8 Ohm impedance.
• 16Ω (16 Ohm) Output: For speaker cabinets with a 16 Ohm impedance.

Важно: Увек повежите amplifier to a speaker cabinet with the correct impedance before turning it on. Operating a tube amplifier without a load can cause severe damage to the output transformer.

4. Power Connection and Voltagе Избор

Connect the provided power cable to the MAINS input on the rear panel and then to a suitable power outlet. Ensure the MAINS SELECT switch is set to the correct voltagза ваш регион (110V или 220V).

5. Улаз за гитару

Повежите своју гитару са IN input jack on the front panel using a standard 6.35mm instrument cable. This is a 1-megohm high-impedance input.

Упутство за употребу

1. Powering On and Standby

1. Ensure all connections (speaker, power, guitar) are secure.
2. Флип тхе ON switch to the 'ON' position. The power indicator light will illuminate.
3. Подесите ПРИЧЕКАТИ switch to 'OFF'. This allows the tubes to warm up with only the filaments heated and no high voltage applied. Wait for approximately 30-60 seconds for the tubes to reach operating temperature.
4. After the warm-up period, flip the ПРИЧЕКАТИ switch to 'ON' for normal operation.

2. Контроле прекоview

The OA-H05 features a single channel with the following controls:

• BRIGHT/WARM Switch: Toggles between a brighter, more articulate tone and a warmer, fuller tone.
• ВОЛУМЕ: Контролише укупни излазни ниво ampлифиер.
• ДОБИТАК: Подешава количину преamp distortion and sustain. Higher gain settings produce more overdrive.
• БАСС: Контролише нискофреквентни одзив.
• СРЕДИНА: Контролише одзив средње фреквенције.
• ТРЕБЛЕ: Контролише одзив високе фреквенције.

3. Tone Shaping

Experiment with the GAIN and VOLUME knobs to achieve various tones, from clean to overdriven. The BRIGHT/WARM switch and the 3-band EQ (BASS, MIDDLE, TREBLE) allow for extensive tonal customization to suit different musical styles and preferences.

Тхе amplifier's single-ended output stage provides a distinct tonal character, often praised for its rich harmonics and dynamic response, especially when pushed into natural tube overdrive.

Одржавање

1. Чишћење

Обришите amplifier's exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish. Ensure the amplifier is unplugged before cleaning.

2. Замена цеви

Tubes have a finite lifespan and may need replacement over time. If you experience a decrease in performance, excessive noise, or inconsistent sound, it may be time to replace one or more tubes. Consult a qualified technician for tube replacement to ensure proper handling and biasing.

When replacing tubes, ensure the amplifier is completely powered off and unplugged, and allow sufficient time for the tubes to cool down. Handle new tubes carefully, avoiding touching the glass with bare hands, as oils can create hot spots and reduce tube life.

Решавање проблема

Нема звука

• Check all power connections and ensure the amplifier is plugged into a working outlet.
• Проверите да ли је ON и ПРИЧЕКАТИ switches are in the correct positions.
• Ensure the speaker cable is securely connected to both the amplifier and the speaker cabinet, and that the speaker impedance matches the ampизлаз лифиера.
• Check your guitar cable and guitar's volume knob.
• Allow adequate warm-up time for the tubes.

Weak or Distorted Sound (Unintended)

• Подесите ГАИН и ВОЛУМЕ controls. High gain settings will naturally produce distortion.
• Check the condition of your tubes. Worn-out tubes can cause weak or muddy sound.
• Ensure the speaker cabinet is functioning correctly.
• Review the Gain Spectrum Schematic to understand how tube amplifiers handle signal clipping compared to solid-state ampлифиерс.

Прекомерна бука или зујање

• Уверите се да су сви каблови правилно заштићени и у добром стању.
• Покушајте да укључите amplifier into a different power outlet or a power conditioner.
• Померите ampдржите уређај даље од других електронских уређаја који могу изазвати сметње.
• Faulty tubes can also introduce noise; consider having them checked.
