Owner's Manual 444
Rear Panel
1. PHANTOM POWER PEDAL Jack: Connect a DC power supply to provide phantom power for your
MIDI pedal. By default the DC jack is connected to pin 1 (center pole) and 3 of the 7-pin MIDI
connector. It can can be internally modified to serve pin 6 and 7.
2. AC JACK / AC VOLTAGE SELECTOR: When changing AC voltage for using the 444 in a different
country, make sure fuse values are correct.
3. GROUND LIFT: Controls whether the 444s audio ground is connected to earth conductor or not.
The chassis is grounded when the switch is in the 'Out' position. We recommend this position when
using the 444 as the input device for your guitar. In case you are using other audio loopers in front
of the 444, you might notice hum noise, which is most often caused by ground loops between two
devices. Switching the ground lift to the 'In' position will solve the issue ina lmost any case.
4. MIDI THRU: If you have several MIDI devices in your setup, connect the MIDI Thru with the MIDI
In of the following device.
5. MIDI IN: Connect a MIDI pedal or any other MIDI device, to control the 444 via Program Change
or Control Change messages. If your MIDI device can be powered via the MIDI cable, connect the
correct DC power supply to the PHANTOM POWER PEDAL jack. Make sure supply voltage and pin
assignment is correct.
6. LINE OUT: Outputs the SPEAKER Outs or FX LOOP Send signal of the currently selected amp at line
level. It can be internally jumpered to be a speakers or an FX send line out. We recommend the
speaker setting, which also is set by default. Note that when feeding the LINE OUT from the FX
Send Bus, it's only active when the chosen amps FX loop is connected and activated!
7. AMP1 SEND: Connect the FX Loop Send/preamp out/line out of Amplifier 1 to the AMP 1 SEND jack
of the 444. Please be aware that this is not an independent loop but the corresponding FX loop of
the amplifier you drive with the AMP INPUT 1 and AMP OUTPUT 1 jacks of the 444!
8. AMP1 RETURN: Connect the FX Loop Return/power amp in/line in of Amplifier 1 to the AMP 1
RETURN of the 444. Like before mentioned, this is not an independent loop but the corresponding
FX loop of the amplifier you drive with the AMP INPUT 1 and AMP OUTPUT 1 jacks of the 444!
9. AMP2/3/4 SEND and AMP2/3/4 Return: Proceed like described under point 7 and 8.
