The DL4™ MkII includes everything in the original DL4 Delay Modeler, while introducing 15 new MkII delays drawn from our HX® family of amp and effects processors and both 4-Switch and 1-Switch loopers with up to 240 seconds of record time (expandable to several hours using an optional microSD card). There's also an XLR microphone input, MIDI In and Out/Thru connectors, heavy duty footswitches, three bypass options, and a jack for connecting an optional expression pedal or two additional footswitches. The DL4 MkII is also smaller and lighter than the original, making it an even more appealing choice for modern musicians.
 
MODEL SELECTOR
Selects the delay or reverb type or the Classic Looper.
 
ALT/LEGACY BUTTON
Toggles between the MkII and Legacy delays. When pressed and held it accesses the alternate functionality of the knobs.
 
TIME/SUBDIV
Adjusts the delay time.
 
REPEATS
Adjusts the delay repeats from one to infinite.
 
TWEAK

FOOTSWITCHES A, B, AND C
The footswitches select presets A, B, and C. When the Looper is active, they select the Record/Overdub, Play/Stop, and Play Once functions.
 
TAP FOOTSWITCH
Tap several times to sync the delay time with your performance (the red LED flashes at the current rate). When using the Looper, Tap selects the half-speed and reverse functions.
 
EXP PEDAL – FS 5/6
Connect an optional expression pedal to control preassigned parameters that differ for each delay type. Use a "Y" cable to connect both an expression pedal and a footswitch, or two footswitches.
 
MIC LEVEL KNOB
Adjusts the input gain of the XLR Mic Input.
 
MIC INPUT
Plug your dynamic microphone into this XLR input.
 
INPUT L/MONO, RIGHT
Connect stereo instruments or pedals to these inputs. Connect mono instruments or pedals to the L/Mono input.
 
OUTPUT L/MONO, RIGHT

MIDI IN, OUT/THRU
These connectors enable the DL4 MkII to receive continuous controller, program change, MIDI Clock, and other MIDI messages.
 
microSD
Inserting a microSD card into this slot automatically enables the Looper to access the card memory rather than internal memory, resulting in increased recording time (determined by the capacity of the card) and the ability to store the current loop.
 
USB C
Connect your computer to perform firmware updates using the free Line 6 Updater app, and to use your MIDI software to select presets and control various parameters, tempo, and more.
 
DC IN
Connect the included Line 6 DC-1g adapter.
