Walrus Audio Mako-serien MKII ACS1 Amp Brukerhåndbok for førerhussimulator

1. Introduksjon

The Walrus Audio Mako Series MKII ACS1 is an advanced amplifier and speaker cabinet simulator designed to provide the sound and feel of world-class amplifiers. It integrates complimentary speaker cabinet Impulse Responses (IRs) from Tone Factor and York Audio, along with controllable room size simulation. This device offers extensive options for delivering guitar tone in various settings, including live performance, studio recording, and home practice. Its user-friendly controls, stereo input and output capabilities, onboard presets, and MIDI support make it a versatile tool for guitarists.

The ACS1 features six distinct amplifier models, each inspired by historically significant amplifiers, and twelve cabinet IRs meticulously designed by industry experts to ensure optimal tonal representation. Custom IRs for the Fullerton, London, and Dartford amp models were engineered by David Hislop and Kenyon Reed at Tone Factor, while Justin York of York Audio designed the IRs for the Red, Citrus, and Tread amp modeller.

4. Oppsett

4.1 Powering the ACS1

Connect a 9V DC (center negative) power supply with a minimum of 300mA to the power input jack on the left side of the pedal. Ensure the power supply meets these specifications to prevent damage.

4.2 Koble til instrumentet

• Mono Setup: Connect your guitar or the output of your pedalboard to the MONO (L) IN kontakten. Koble til MONO (L) OUT jack til din amplifier, mikser eller lydgrensesnitt.
• Stereooppsett: For stereo input, connect your stereo source to both the MONO (L) IN og STEREO (R) IN jacks. For stereo output, connect the MONO (L) OUT og STEREO (R) OUT jacks to two separate inputs on your mixer or audio interface.

The ACS1 is designed to be placed at the end of your pedal chain, before your amplifier or directly into a mixer/audio interface, to simulate the full amplifier and cabinet sound.

5. Bruksanvisning

5.1 Grunnleggende betjening

Once powered on, the ACS1 will display its current settings. Use the BYPASS footswitch to engage or disengage the effect. The BOOST/PRESET footswitch can be used to cycle through presets or engage a boost, depending on the configured mode.

5.2 Justering Amplifier and Cabinet Settings

The top row of knobs (VOL, GAIN, ROOM) and the bottom row of knobs (BASS, MIDDLE, TREBLE) directly control the parameters displayed on the screen. Turning these knobs will adjust the corresponding values.

Figure 4: EQ and Cabinet Selection. This close-up of the ACS1 display shows the Bass, Middle, and Treble EQ settings, along with the selected cabinet (CAB 1) and its type (LONDON). The L+R indicator suggests stereo operation.

Velger Amp Models and Cabinet IRs:

The display screen allows you to navigate and select different amplifier models and cabinet IRs. Consult the full Walrus Audio manual available on their website for detailed instructions on menu navigation and parameter selection. The ACS1 comes pre-loaded with six amp models and twelve cabinet IRs.

5.3 Room Simulation

The ROOM knob adjusts the simulated acoustic space around the amplifier and cabinet. This adds depth and realism to your tone. The display will show the current room type and size.

Figure 5: Room Settings Display. This image shows the ACS1 display indicating the "ROOM" parameter, with "TYPE ROOM 2" and "SIZE" visible, allowing users to adjust the simulated room acoustics.

5.4 forhåndsinnstillinger

The ACS1 supports onboard presets, allowing you to save and recall your favorite settings. The BOOST/PRESET footswitch can be configured to cycle through these presets. Refer to the official Walrus Audio documentation for detailed instructions on saving, loading, and managing presets.

Figure 6: Preset Selection Interface. This display shows the "PRESET" menu, with options for selecting different preset slots (A, B, C) and their corresponding numbers (0, 2).

5.5 Advanced Features (Noise Gate, Output EQ, MIDI)

The ACS1 includes additional features accessible through its menu system:

• Støyport: Helps to reduce unwanted noise and hum, especially with high-gain settings. Parameters like Threshold and Release can be adjusted.
• Utgangs-EQ: Provides further tonal shaping options for the overall output.
• MIDI-kontroll: The ACS1 supports MIDI for external control of parameters, preset changes, and synchronization with other MIDI-enabled devices.

5.6 Custom IRs and Firmware Updates

The ACS1 allows users to load their own Impulse Responses (IRs) and update the pedal's firmware. This functionality is managed through the Walrus Audio webnettstedet. Besøk walrusaudio.io for detailed instructions and software tools required for these operations.

6. Vedlikehold

• Rengjøring: Use a soft, dry cloth to clean the exterior of the pedal. Do not use abrasive cleaners or solvents.
• Lagring: Oppbevar pedalen på et tørt og kjølig sted, unna direkte sollys og ekstreme temperaturer.
• Kabelpleie: Ensure all cables are in good condition and properly connected. Avoid bending cables sharply or placing heavy objects on them.

7. Feilsøking

7.1 Ingen lydutgang

• Sjekk strøm: Ensure the pedal is receiving proper 9V DC power and the power supply is functioning.
• Kabeltilkoblinger: Verify all audio cables are securely connected to the correct input and output jacks.
• Bypass Status: Ensure the pedal is not in bypass mode. The BYPASS footswitch LED should indicate the effect is active.
• Voluminnstillinger: Check the VOL knob on the ACS1 and the volume settings on your ampovn eller mikser.

7.2 Unwanted Noise or Hum

• Strømforsyning: Use a high-quality, isolated power supply. Daisy-chaining power supplies can introduce noise.
• Bakkeløkker: Try isolating power to different pedals or using a ground loop isolator if necessary.
• Støyport: Engage and adjust the built-in Noise Gate feature to reduce hiss or hum.
• Kabelkvalitet: Ensure you are using shielded instrument cables.

7.3 Pedal Not Responding to Controls

• Strømsyklus: Disconnect and reconnect the power supply to reset the unit.
• Fastvare: Ensure your firmware is up to date. Check walrusaudio.io for de nyeste versjonene.
