- For stereo operation, connect the left channel to IN (Mono L) and the right channel to STEREO (R).
- Аўдыявыхад:
- For mono output, connect the OUT (Mono L) дамкрат да вашага amplifier or next effects pedal.
- For stereo output, connect the left channel to OUT (Mono L) and the right channel to STEREO (R).
- MIDI (неабавязкова): If using MIDI control, connect your MIDI controller to the MIDI IN порт.
Operating Modes (Delay Algorithms)
The D1 MKII offers six distinct delay algorithms, each with unique characteristics and adjustable parameters via the TWEAK and ATTACK knobs.
1. Digital
A pristine, clear delay with high-fidelity repeats. Ideal for rhythmic delays where clarity is paramount.
2. Мод
Adds modulation to the delay repeats, creating lush, swirling textures. The TWEAK and ATTACK knobs control modulation depth and rate.
3. Вінtage
Emulates the warm, decaying repeats of analog and tape delays. Repeats gradually lose fidelity and clarity.
4. Двайны
Features two independent delay lines that can be set to different subdivisions, creating complex rhythmic patterns. The redesigned Dual mode allows for unique tap divisions on each channel.

5. Рэверс
Plays delay repeats backward, creating ethereal and atmospheric effects. The TWEAK and ATTACK knobs can control the attack and decay of the reversed repeats.
6. Grain
A granular delay algorithm that slices the audio into small "grains" and manipulates them to create unique textures, from shimmering ambient washes to glitchy stutters. This is an all-new program for the MKII.

Прасэты
The D1 MKII allows users to save and recall up to 128 presets, providing quick access to your favorite delay settings. Presets can be accessed and managed via the OLED display and footswitches, or through MIDI control.
- Захаванне перадусталёўкі: Adjust the pedal to your desired settings. Refer to the on-screen menu for specific instructions on how to save the current state to a preset slot.
- Выклік прэсета: Use the TAP footswitch to cycle through presets or navigate the menu to select a specific preset.
MIDI -кантроль
The D1 MKII supports MIDI control for advanced integration into your rig. MIDI allows for remote control of parameters, program changes (preset recall), and synchronization with other MIDI-enabled devices.
- Connect your MIDI controller to the MIDI IN порт.
- The MIDI ПРАЗ port can be used to daisy-chain MIDI data to other pedals.
- Refer to the Walrus Audio website for detailed MIDI implementation charts and CC messages.
Тэхнічнае абслугоўванне
- Уборка: Выкарыстоўвайце мяккую сухую тканіну для чысткі вонкавага боку педалі. Пазбягайце выкарыстання абразіўных ачышчальнікаў або растваральнікаў.
- захоўванне: Захоўвайце педаль у прахалодным, сухім месцы, удалечыні ад прамых сонечных прамянёў і экстрэмальных тэмператур, калі яна не выкарыстоўваецца.
- крыніца харчавання: Always use a regulated 9V DC, center-negative power supply with a minimum of 300mA. Using an incorrect power supply can damage the unit and void the warranty.
- Абнаўленні прашыўкі: Periodically check the Walrus Audio website for firmware updates via the USB-C port to ensure optimal performance and access to new features.
