Rear Panel Description
1. Power input jack. 2.5mm center pin. Connect to a source of 9 to 12 VAC at 1amp.
2. MIDI In jack. 7 pin DIN. Connect to the output of a MIDI controller to control Loop/Control Function status. This jack also
supplies 9/12 VAC phantom power on pins 6 & 7. WARNING: This jack is wired in parallel with the front panel 4pin XLR
connector. Do not use this jack at the same time you are using the front panel XLR.
3. MIDI Out/Thru jack. 7 pin DIN. Connect to the MIDI In of the same device in the MIDI chain. Signal appearing here is the
same as that at the MIDI In jack.
4. Chain B Output. This jack is the output of series Chain B and is in parallel with the front panel Chain B Output jack. In
addition, signal appearing at this jack feeds both Switchable Output circuits 1 and 2. Both front and rear panel jacks are
active and can be used at the same time.
5. Chain B loop 4 Send/Return jacks. Connect Send to effect input, Return to effect output when using as a series in-line
bypass loop. If you are using all or part of this chain as a switchable signal splitter, connect send to effect input and leave
return unconnected. See Block Diagram for signal path configuration.
6. Chain B Series Loop 3 Send/Return jacks. See #5 and Block Diagram for details.
7. Chain B Series Loop 2 Send/Return jacks. See #5 and Block Diagram for details.
8. Chain B Series Loop 1 Send/Return jacks. See #5 and Block Diagram for details.
9. Chain B Input. This jack is the input to the 4 Chain B Series loops. This jack is “normalled” to the Chain A output jacks
(front and rear). Inserting a mono 1/4” plug “breaks” the “normalled” connection between Chain A and Chain B. NOTE:
The front panel Chain B Input jack has priority over this jack when used. See Block Diagram for details. This input can be
buffered to prevent signal loss depending on the setting of the front panel Chain B buffer switch.
10. Chain A Output. This jack is the output of series Chain A and is in parallel with the front panel Chain A Output jack. This
jack is also “normalled” to the Chain B Input jack. Both front and rear panel jacks are active and both can be used at the
same time. NOTE: This jack is perfect for connecting to a tuner input.
11. Chain A Series Loop 4 Send/Return jacks. See #5 and Block Diagram for details.
12. Chain A Series Loop 3 Send/Return jacks. See #5 and Block Diagram for details.
13. Chain A Series Loop 2 Send/Return jacks. See #5 and Block Diagram for details.
14. Chain A Series Loop 1 Send/Return jacks. See #5 and Block Diagram for details.
15. Chain A Input. This jack is the input to the 4 Chain A series loops. NOTE: The front panel Chain A Input jack has priority
over this jack when used. See Block Diagram for details. This input can be buffered to prevent signal loss depending on
the setting of the front panel Chain A buffer switch.
