3. Продукт закінчивсяview
The PO modular400 is an analog synthesizer featuring a comprehensive set of modules for sound generation and manipulation. It includes a step sequencer, mixer, various oscillators (square wave, sawtooth wave, sine wave), a sample & hold module, LFO, envelope generators, voltagелектронний контроль amplifiers (VCAs), a noise generator, and a filter. It operates on 8 AA batteries or an optional external power adapter.

Key Modules:
- Oscillators (VCOs): Generate the primary sound waves (square, sawtooth, sine).
- Змішувач: Combines audio signals from different sources.
- Послідовність кроків: Creates rhythmic patterns and melodies.
- Sampле та утримуйте: Generates random or stepped voltagес.
- LFO (Low-Frequency Oscillator): Produces slow oscillations for modulation effects.
- Envelope Generators (EG): Формує amplitude or other parameters of a sound over time.
- VCA (томtage-Controlled Ampліфтер): Controls the volume of a signal using a control voltage.
- Генератор шуму: Produces white noise for percussive sounds or effects.
- Фільтр: Shapes the tonal characteristics of a sound by removing certain frequencies.
- Доповідач: Integrated speaker for direct audio output.
4. Налаштування
4.1 Збірка
The PO modular400 comes as a kit requiring assembly. Follow the included visual instructions for attaching the modules to the chassis and securing them with the provided screws. Ensure all connections are firm before proceeding.

4.2 Живлення пристрою
The PO modular400 can be powered by 8 AA batteries or an optional external power adapter (sold separately). Insert the batteries into the battery compartment located at the base of the unit, ensuring correct polarity. If using an external adapter, connect it to the designated power input jack.
4.3 Початкові підключення
Before creating complex patches, familiarize yourself with the basic signal flow. A common starting point is to connect an oscillator's output to a VCA's input, then the VCA's output to the mixer, and finally the mixer's output to the speaker or an external audio interface.
5. Інструкція з експлуатації
5.1 Module Functions
Each module has specific inputs and outputs (jacks) and controls (knobs). Understanding their individual functions is key to creating sounds.
- Oscillators (Square, Saw, Sine): Використовуйте мелодія knob to adjust pitch and рівень to control output volume. The керуючий ключ input allows for pitch modulation.
- Змішувач: Features multiple inputs (1, 2, 3) and a single output. Use the individual рівень knobs to blend signals.
- Секвенсер: Controls include темп, clock in, скинути, and individual step outputs (D1-D4).
- LFO: Generates low-frequency waveforms (square, triangle) for modulation. Adjust швидкість to change speed.
- Фільтр: Shapes the timbre. Частота controls the cutoff point, and резонанс adds emphasis at the cutoff.
- Envelope (ENV): Generates a voltage contour. Typically used to control the VCA's gain over time.
- VCA: Acts as a voltage-controlled volume knob. The посилення knob sets the maximum level, and the КОНТРОЛЬ input modulates it.
- Шум: Provides white noise output.
- Доповідач: Підключіть аудіосигнал до поза jack to hear sound directly from the built-in speaker.

5.2 Латки
Patching involves connecting modules using the provided patch cables to create signal paths. Experiment with different connections to understand how modules interact. For example, an LFO output can be patched to an oscillator's control key input for vibrato, or to a filter's control input for wah-like effects.
5.3 Зовнішні з'єднання
The PO modular400 can be integrated with other modular systems or semi-modular synthesizers. You can connect additional envelopes or other modules from external systems to expand its capabilities. Ensure voltage compatibility when connecting to external gear.
6. Технічне обслуговування
6.1 Очищення та зберігання
To maintain your PO modular400, wipe the surface with a soft, dry cloth. Avoid using abrasive cleaners or solvents. Store the unit in a dry, dust-free environment away from direct sunlight and extreme temperatures.
6.2 Заміна батареї
When the sound quality degrades or the unit fails to power on, it's likely time to replace the batteries. Open the battery compartment at the base of the unit and replace all 8 AA batteries with new ones, ensuring correct polarity. Dispose of old batteries responsibly.
7. Вирішення проблем
If you encounter issues with your PO modular400, refer to the table below for common problems and their solutions.
| проблема | Можлива причина | Рішення |
|---|---|---|
| Немає звуку. | Incorrect patching; low batteries; speaker volume too low; external output not connected correctly. | Check all patch cable connections. Replace batteries. Increase speaker volume. Ensure external audio device is properly connected and powered. |
| Спотворений звук. | Signal levels too high; faulty patch cable. | Reduce module output levels or mixer input levels. Try a different patch cable. |
| Пристрій не вмикається. | Dead batteries; incorrect battery insertion; power adapter issue. | Replace batteries, ensuring correct polarity. Check power adapter connection and functionality. |
| Knobs are stiff or difficult to turn. | Manufacturing tolerance; dust accumulation. | This can be a characteristic of the design. Gentle, consistent use may ease them. Avoid forcing. |
