Front Panel Description
1. Chain A Input (This jack has priority over the rear panel Chain A Input).
2. Chain A Input buffer select switch. Push in to engage Chain A Input buffer. Gain is factory set at +1db. Switch out hard-wire
bypasses the buffer circuit. Buffer input impedance is 500k Ohms.
3. Chain A Output. This jack is in parallel with the rear panel Chain A Output jack and is “normalled” to the Chain B Input jack.
4. Chain B Input (This jack has priority over the rear panel).
5. Chain B Input buffer select switch. This switch functions the same as the Chain A switch, but for Chain B.
6. Chain B Output. This jack is in parallel with the rear panel Chain B Output jack. In addition, signal appearing at this jack
feeds both Switchable Output circuits 1 and 2.
7. Switchable Output 1. This is a buffered low impedance audio output when engaged via MIDI. Signal appearing at this jack
(when active) is the same as that appearing at the Chain B output jack. As an option, this output can be transformer isolated
to eliminate ground loop hum when connected to an amplifier input. When not engaged, no signal appears at this output.
NOTE: THIS OUTPUT JACK HAS PRIORITY OVER THE CONTROL 1 JACK. That is, both jacks may NOT be used at the
same time! You must choose which type of function you want to use; a switchable audio out, or a “footswitch-type” control
function.
8. Control 1. This is an isolated “normally open”, latching “switch-to-ground” control function. When activated via MIDI
(LED “on”), a relay shorts the jack tip to sleeve. NOTE: This function is not available if you are using the Switched Output
jack. See above.
9. Switched Output 2. Same as Switched Output 1. See #7.
10. Control 2. Same as Control 1. See #8. NOTE: This function not available if using the Switched Output 2 jack. See #7.
11. Control 3. Same as Controls 1 and 2. See #8. This jack has priority over the “Control #3 function” of the Control 3/4 jack,
when used. See #12.
12. Control 3/4. This stereo (TRS) jack has 2 “normally open” control functions similar to Controls 1, 2 and 3. Control 3, when
activated via MIDI, shorts ring to sleeve. Control 4, when activated via MIDI, shorts tip to sleeve. NOTE: All 4 control
functions are ground isolated to prevent ground loop hum.
13. Loop/Control Function LED status indicators. LED “on” indicates loop is active, LED “off”, loop is bypassed. The same is
true with Control Functions: LED “on”, tip is shorted to sleeve; LED “off”, tip/sleeve is open. With Switchable Outputs;
LED “on” indicates audio at the Switched Output jack. LED “off”, audio is muted.
14. Power indicator LED. When “on”, 9VAC power is applied to the unit.
15. “To RS-10” XLR connector. Used to connect CAE RS-10 MIDI Foot Controllers. Supplies 9VAC phantom power to the
RS-10 on pins 1 and 2, and provides MIDI in to the 2x4 on pins 3 and 4. CAUTION: DO NOT USE BOTH THE FRONT
PANEL XLR AND THE REAR PANEL MIDI IN AT THE SAME TIME OR DAMAGE TO THE UNIT MAY RESULT.
