Congratulaons on your purchase of the SKRYDSTRUP R&D MR10 Loop System.
The MR10 Loop System was designed to provide ulmate flexibility in signal roung, combined with the best audio performance possible.
The MR10 Loop System ulizes a unique unity-gain buffer circuit in every audio loop, designed by SKRYDSTRUP R&D, to maintain correct impedances
throughout the enre system and to avoid the cross-loading affect between stomp boxes / effect units. Furthermore, each input/send/return/output
features our unique RFI protecon.
This manual will introduce you to the MR10 Loop System and its features. Aer reading this manual please keep it for future reference.
We are confident that you very quickly will be familiar with the MR10 Loop System, and appreciate the versality and high quality of this unit.

PRECAUTIONS
DO NOT aempt to service this unit. Doing so will void this warranty.
DO NOT remove the cover from this unit at any me. Doing so will void this warranty.
DO NOT plug the output from a Power Amplifier directly into any of the in- or outputs of this unit. Doing so may result in damage to the unit.
This unit is designed to handle instrument and line level signals only.
DO NOT expose this unit to excessive heat. This unit is designed to operate between 0C and 40C.
DO NOT use this unit near water. Care should be taken so that objects do not fall and liquids are not spilled into the unit through any openings.
DO NOT use solvents such as benzine etc., to clean the exterior. Use a dry socloth to remove dust, dirt and finger marks.

REAR PANEL
9VAC: 2.1mm DC barrel.
MIDI IN: Standard 5pin DIN connector.
The MIDI IN connector must be connected to the MIDI OUT connector of a transming MIDI device via a standard cable, in order for the loop system
respond to MIDI commands originang from these devices.
MIDI THRU: Standard 5pin DIN connector.
The MIDI THRU connector will forward the incoming MIDI data to any MIDI device.
GND/LIFT: Mini toggle switch. Set for minimum hum. When in LIFT posion the audio ground is lied from the chassis.
LOOP 10 OUT: 1/4” mono jack, which provide an output of the audio signal from Loop 1 - Loop 10, or Loop 6 - Loop 10, depending on how the LINK/GROUP mini
switch is set.
LOOP 7 IN: 1/4” mono jack, that provide input to group 2. Only acve when the mini toggle switch is set to GROUP.
This input ulizes our highly recognized high impedance input buffer.
LINK/GROUP: Mini toggle switch. When set to LINK the signal is routed through all 10 loops. Loop 6 OUT and Loop 7 IN is disabled.
When set to GROUP the MR10 is divided into two groups of loops.
Group 1 is loop 1 - loop 6, and group 2 is loop 7 - loop 10. Loop 6 OUT and Loop 7 IN is enabled.
LOOP 6 OUT: 1/4” mono jack, which provide an output of the audio signal from group 1. The output is only acve when the mini toggle switch is set to GROUP.
When the mini toggle switch is set to LINK, the output is disabled.
LOOP 1 IN: 1/4” mono jack used to provide input to the MR10 Loop System. This input ulizes our highly recognized high impedance input buffer.
TUNER OUT: 1/4” mono jack. Provides a transformer isolated tuner output.
LOOP RETURN: 1/4” mono jacks that accept the output of any external device. The inseron of a plug will break the internal normalling to the SEND jack.
Each RETURN is fed to a unity gain line driver, which is only acve when the loop is acvated.
LOOP SEND: 1/4” mono jacks that are used to provide switchable outputs to any external device input.
FRONT PANEL
LED’s indicang status of each loop. When lit the loop is acve. EDIT switch. Tacle switch for eding the MR10 Loop System.

MIDI CONTROL ASSIGNMENTS
HOW TO EDIT THE MIDI CHANNEL:
-Unplug the power from the MR10 Loop System.
- Press the EDIT buon and hold it while connecng power to the unit.
- Press the EDIT buon repeatedly unl the desired MIDI channel is selected. Look at the MIDI channel diagram below.
- When the desired MIDI channel is selected, press the EDIT buon for 2 seconds. The LED’s will now blink to indicate that the programming is stored.
MIDI CONTROL CHANGE NUMBERS:
LOOP 1 is CC# 11 LOOP 6 is CC# 16
LOOP 2 is CC# 12 LOOP 7 is CC# 17
LOOP 3 is CC# 13 LOOP 8 is CC# 18
LOOP 4 is CC# 14 LOOP 9 is CC# 19
LOOP 5 is CC# 15 LOOP 10 is CC# 20
The MIDI controller numbers can be changed by soware revision.
Contact SKRYDSTRUP R&D for details.
MIDI PROGRAM CHANGE:
Select a preset on your MIDI Foot Controller, or MIDI controlling device.
By pressing the EDIT buon, you can now scroll through Loop 1 - 10. Press the EDIT buon once and the LED of Loop 1 will start flashing.
If you wish to acvate the loop, hold the EDIT buon for 2 seconds. The LED’s will flash three mes to indicate that the selecon has been stored.
Repeat the procedure if addional loops should be acvated or deacvated within the selected preset.
