3. Izdelek je končanview
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, voltage-nadzorovano 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).
- Mešalnik: Combines audio signals from different sources.
- Sekvencer korakov: Creates rhythmic patterns and melodies.
- Sample & Hold: Generates random or stepped voltages.
- LFO (Low-Frequency Oscillator): Produces slow oscillations for modulation effects.
- Envelope Generators (EG): Oblikuje amplitude or other parameters of a sound over time.
- VCA (zvtage-nadzorovano Ampdvigalo): Controls the volume of a signal using a control voltage.
- Noise Generator: Produces white noise for percussive sounds or effects.
- Filter: Shapes the tonal characteristics of a sound by removing certain frequencies.
- govornik: Integrated speaker for direct audio output.

4.2 Napajanje naprave
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 Začetne povezave
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.

5.1 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): Uporabite melodija knob to adjust pitch and raven to control output volume. The nadzorni ključ input allows for pitch modulation.
- Mešalnik: Features multiple inputs (1, 2, 3) and a single output. Use the individual raven knobs to blend signals.
- Sekvencer: Controls include tempo, clock in, ponastaviti, and individual step outputs (D1-D4).
- LFO: Generates low-frequency waveforms (square, triangle) for modulation. Adjust stopnja to change speed.
- Filter: Shapes the timbre. Pogostost controls the cutoff point, and resonanca 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 dobiček knob sets the maximum level, and the nadzor input modulates it.
- Hrup: Provides white noise output.
- govornik: Priključite zvočni signal na ven jack to hear sound directly from the built-in speaker.

5.2 Krpanje
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 Zunanje povezave
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. Vzdrževanje
6.1 Čiščenje in skladiščenje
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 Zamenjava baterije
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. Odpravljanje težav
If you encounter issues with your PO modular400, refer to the table below for common problems and their solutions.
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Ni zvoka. | 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. |
| Popačen zvok. | Signal levels too high; faulty patch cable. | Reduce module output levels or mixer input levels. Try a different patch cable. |
| Enota se ne vklopi. | 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. |
