4.1. Amplifier Head (AO900)
- INPUT: 1/4-inch jack for instrument connection.
- PASSIVE/ACTIVE Switch: Selects input impedance for passive or active instruments.
- COMP: Säätelee signaaliin sovellettavan kompression määrää.
- AJAA: Adjusts the amount of distortion from the Alpha Omega engine.
- TASO: Sets the output level of the distorted signal.
- MOD: Blends between the Alpha (tight, percussive) and Omega (brutal, raw) distortion circuits.
- SEKOITUS: Mixes the clean input signal with the distorted signal from the Alpha Omega engine.
- SAADA: Controls the overall gain of the Alpha Omega engine.
- MURISTA: A switch that provides a bass boost for a thicker, more powerful tone.
- PURRA: A switch that provides a treble boost for added presence and clarity.
- Graafinen taajuuskorjain: Four sliders visible on the front panel (250 Hz, 500 Hz, 1.5 kHz, 5 kHz) allow for precise frequency adjustments. The amplifier features a 6-band graphic equalizer in total.
- MYKISTÄ: Mykistää ampnostimen lähtö.
- HALLITA: Ohjaa laitteen kokonaislähtövoimakkuutta ampelävämpi.
4.2. Intelligent Footswitch (IFS)
- Footswitch Button: Toggles the distortion engine on/off or mutes the amplifier, depending on the programmed function.
- VIRTA-LED: Osoittaa ampnostin on päällä.
- DISTORTION LED: Indicates when the Alpha Omega distortion engine is active.
- MUTE LED: Osoittaa, kun amplifier's output is muted.
5. Käyttöohjeet
To operate your Darkglass AO900 and IFS Footswitch:
- After completing the setup, ensure all volume controls (including HALLITA) are set to a low level before playing.
- Lisää vähitellen HALLITA volume to your desired listening level.
- Käytä AJAA, TASO, MOD, SEKOITUS, ja SAADA controls to dial in your desired distortion tone. Experiment with the MURISTA ja PURRA switches for additional tonal variations.
- Adjust the graphic equalizer sliders (250 Hz, 500 Hz, 1.5 kHz, 5 kHz) to fine-tune your frequency response.
- Engage the compressor using the COMP knob to control dynamics.
- Use the IFS Footswitch to remotely activate/deactivate the distortion engine or mute the amplifier as needed during performance. The corresponding LEDs on the footswitch will indicate the active status.
- For silent practice, connect headphones to the headphone output and use the auxiliary input for backing tracks.
6. Huolto
Asianmukainen huolto varmistaa laitteen pitkän käyttöiän ja optimaalisen suorituskyvyn ampelävämpi:
- Puhdistus: Käytä pehmeää, kuivaa liinaa puhdistaaksesi amplaitteen ulkopintaa. Vältä hankaavia puhdistusaineita tai liuottimia.
- Varastointi: Säilytä ampviileässä, kuivassa paikassa, poissa suorasta auringonvalosta ja äärimmäisistä lämpötiloista.
- Ilmanvaihto: Varmista asianmukainen ilmanvaihto laitteen ympärillä ampylikuumenemisen estämiseksi. Älä tuki tuuletusaukkoja.
- Kuljetus: When transporting, use appropriate protective cases to prevent physical damage.
7. Vianmääritys
Jos kohtaat ongelmia, harkitse seuraavia yleisiä vianmääritysohjeita:
- Ei virtaa: Check the power cable connection and the power outlet. Ensure the power switch is ON.
- Ei ääntä: Verify all cable connections (instrument, speaker, footswitch). Check the HALLITA volume and ensure the MYKISTÄ function is not active on the amplifier or footswitch. Confirm your instrument is working correctly.
- Distorted Sound (unintended): Check input gain levels and ensure they are not excessively high. Adjust AJAA ja TASO valvontaa.
- Jalkakytkin ei reagoi: Varmista, että jalkakytkimen kaapeli on kytketty kunnolla.
- Ylikuumeneminen: Varmista, että amplifier has adequate ventilation. If the amplifier shuts down due to overheating, allow it to cool down before restarting.
If problems persist, consult a qualified technician.
