Retaining the tone, vibe, and creative inspiration of iconic analog delay units, yet adding the versatility of the most modern and expandable delay pedals available today.
Discovery Delay – Terminology Terminology Here is a list of a few common terms used in this manual. Please familiarize yourself with the terms you do not already know. Understanding these terms will better help you understand how to use the Discovery Delay, or any delay for that matter. Signal A signal in this text refers to an audio signal, which is a representation of sound in the form of changing level of electrical voltage.
Discovery Delay – Terminology Beats Per Minute (BPM) ‘Beats Per Minute’ refers to the tempo (speed) of a piece of music. A beat refers to a quarter note in a measure, so 4 beats would equal 1 measure. 120 BPM would equate to 120 quarter notes in a minute if only quarter notes were played for a whole minute. Modulation To modulate is to continually change the value of a parameter. In the case of this delay, the parameter that is being continually altered is the delay time.
Discovery Delay – Overview Diagram Overview Diagram 1 9 2 3 10 4 11 12 5 13 7 14 15 16 8 17 6 1. 7 Segment Display The display shows multiple information from milliseconds of the delay time (ms), to the BPM (by holding the division switch), to the preset number and global menu navigation. 2. Preset/Select/Hold To Edit Buttons This switch allows you to access and save your presets as well navigate global settings. 3.
Discovery Delay – Overview Diagram 5. Lo Cut Knob The low cut reduces bass from the delayed signal only. Fully counter-clockwise is no low (bass) cut. Full clockwise results in maximum low cut. 6. Hi Cut Knob: The high cut reduces high frequencies from the delayed signal. Fully counter-clockwise is the brightest and clearest tone (no high-cut), clockwise will be the darkest. 7. Bypass LED Turns on when the pedal effect is on and off when the pedal is in bypass mode. 8.
Discovery Delay – Overview Diagram 12. Time Knob The time knob can be used to alter the milliseconds (in 5ms increments) or BPM (range 55-250BPM), depending on which is shown on the display. The range in milliseconds accessed by the knob is 40ms - 1100ms. You can manually adjust millisecond/BPM times (in 1ms increments) with the [▲] and [▼] buttons to get specific delay times. 13. Modulation Depth Knob The depth knob controls how intense the modulation of the delay is. 14.
Discovery Delay – Inputs & Outputs Inputs & Outputs 1 2 3 4 5 6 7 8 1. 18VDC Power Input The Discovery Analog Delay requires an 18V, center negative power supply with 250mA of available current. For more details, refer to the technical specifications on page 37. 2. External Switch (Stereo TRS 1/8”) The External Switch allows you to plug in a TRS 1/8” (3.5mm) cable to connect a momentary dual foot switch to control the pedal in one of 3 modes.
Discovery Delay – Inputs & Outputs 4. Output (Mono TS 1/4”) Plug the output of the effect to the next device. 5. Expression Pedal (Stereo TRS 1/4”) The expression pedal input allows you to connect a low impedance 10K ohm expression pedal to control all the knobs per preset. For details on how to use the mapping process for the expression pedal, refer to page 20. 6. Input (Mono TS 1/4”) The input should be connected to your guitar, the previous effects output, or the effects send of an amplifier or mixer.
Discovery Delay – Controls Controls Bypass Foot Switch The bypass switch has a few functions 1. To bypass (turn off) the effect 2. To jump to a lower adjacent preset when in “Preset Mode” 3. To select a preset when using an external 2 button foot switch in the EXT SW jack The Discovery delay has the option to bypass the effect in two ways... True Bypass (input is physically connected to output, completely taking all circuitry out of the signal path. This will cut off any echoing repeats).
Discovery Delay – Controls Mix Knob The [MIX] knob mixes in (or out) the delay effect. It also mixes in or out your guitar signal. Example Mix Settings: 100% Dry / 0% Wet 100% Dry / 100% Wet 0% Dry / 100% Wet From full counter clockwise to the middle, the knob is mixing the wet delay effect from 0-100% From middle to full clockwise, the wet delay effect stays 100%, while your dry guitar signal fades out from 100% to 0% (at full clockwise).
Discovery Delay – Controls Regen Knob The [REGEN] knob sets the amount of feedback off the delay back to its internal input mixer. This controls how long the delay repeats last until they decay away. Due to the internal limiter in the regen circuit, maxed out regen settings allow for distorted self oscillations and sound effects. Hi Cut Knob The high cut reduces high frequencies from the delayed signal, giving you a “darker” sound commonly associated with bucket brigade analog delay pedals.
Discovery Delay – Controls tone. A full counter-clockwise position results in no low cut. Full clockwise results in maximum low cut. Speed Knob The [SPEED] knob controls the speed of a LFO (low frequency oscillator), which controls the delay time around the center of what is displayed on the display. Changing the delay time automatically like this causes an audible pitch bend in the delayed signal, causing a chorusing effect. This is commonly known as “modulated delay”.
Discovery Delay – Controls Holding the division button will toggle the display to show milliseconds (ms) or BPM of the delay time. A dot in the bottom right corner of the display indicates you are looking at the BPM. 8 85 80 80 8 81 82 80 Preset Select (Edit Save) The [PRESET SELECT] button has multiple functions.
