1. บทนำ
The Keeley Halo Andy Timmons Dual Echo pedal is a sophisticated delay effect designed to replicate Andy Timmons' signature delay sound. This pedal offers two independent delay settings (A and B) that can be switched between, along with a dedicated 'Halo' rhythm mode. It features a memory bank for storing presets and versatile controls for shaping your delay tone.
2. การตั้งค่า
2.1 การเชื่อมต่อสายไฟ
Connect a standard 9V DC power supply (center negative) to the 9VDC input jack on the top of the pedal. Ensure the power supply meets the pedal's requirements to prevent damage.
2.2 การเชื่อมต่อเสียง
Connect your instrument or the output of a preceding pedal to the input jack. Connect the output jack to your amplifier or the input of a subsequent pedal. The Halo pedal supports both mono and stereo operation. Refer to the diagram below for typical connections.

3. Operating the Pedal
3.1 การควบคุมมากกว่าview
- TIME/HPF Knob: Controls the delay time. Pressing and holding this knob engages the High-Pass Filter (HPF) function, allowing you to filter the delay repeats.
- FDBK (PRESS) ALT Knob: Adjusts the feedback (number of repeats) of the delay. Pressing and holding this knob activates the Alternate function, which can vary depending on the selected delay mode.
- LEVEL/SATURATE Knob: Sets the overall output level of the delay effect. Pressing and holding this knob engages the Saturate function, adding a subtle drive or warmth to the repeats.
- RATE/TONE Knob: In most modes, this controls the modulation rate. Pressing and holding this knob activates the Tone control, allowing you to brighten or darken the delay repeats.
- DEPTH/RHYTHM Knob: Controls the modulation depth. Pressing and holding this knob engages the Rhythm mode selector, which allows you to choose different delay subdivisions, including the unique 'Halo' effect.
- A/B Footswitches: These footswitches allow you to toggle between two independent delay settings (A and B). The corresponding LEDs indicate the active setting.
- PRESETS LEDs (1, 2, 3): Indicate the currently selected preset. The pedal can store up to eight presets.
- ไฟ LED แสดงสถานะ: Indicates the pedal's bypass status and other operational information.
3.2 Switching Between Delay Settings (A/B)
Press the 'A' footswitch to activate delay setting A, or the 'B' footswitch to activate delay setting B. Each setting can have its own unique parameters for Time, Feedback, Level, Rate, and Depth. This allows for quick transitions between different delay sounds during performance.
3.3 Engaging the 'Halo' Effect
To access the 'Halo' effect, press and hold the DEPTH/RHYTHM knob. This will cycle through various rhythm modes, including the specific 'Halo' setting that provides Andy Timmons' signature delay sound. Experiment with the เวลา และ เอฟดีบีเค controls to fine-tune the effect.
3.4 ค่าที่ตั้งล่วงหน้า
The Halo pedal features a memory bank capable of storing up to eight presets. To save a preset, dial in your desired sound, then refer to the full manual for the specific save procedure (typically involving holding down a footswitch or combination of controls). To recall a preset, use the designated preset selection method, which will illuminate the corresponding PRESETS LED (1, 2, or 3).
คุณสมบัติขั้นสูง 3.5 ประการ
- แตะจังหวะ: The pedal includes a tap tempo function for synchronizing delay time to your playing. Consult the full manual for tap tempo activation.
- Infinite Hold: An infinite hold feature allows for sustained delay repeats.
- Trails/True Bypass: The pedal can operate in either trails mode (delay repeats decay naturally after bypass) or true bypass mode (signal is completely removed when bypassed).
- Expression Pedal Control: An external expression pedal can be connected to control various parameters in real-time.
