Connect the enclosed footswitch to the FOOTSWITCH jack. The footswitch allows you to recall the four
effects presets.
43
MIDI IN. This connector gives you MIDI remote control over your ULTRACOUSTIC. You can change
effects programs by means of program change commands.
44
The TUNER output always provides the instrument channels audio signal to feed an external tuner.
45
The balanced DIRECT OUT jack provides a line-level copy of the instrument channels signal. Use this
jack to connect an external power amp or mixing console.
46
Your ULTRACOUSTIC also features a serial stereo master insert path, which allows you to insert
external effects devices. These are the MASTER INSERT SEND jacks for the left and right channels,
which should be connected to the inputs of the external effects device. You can also tap a stereo signal
from these connectors.
47
These are the MASTER INSERT RETURN jacks for connection to the outputs of an external effects
device.
+ Please note that when using the serial effects path, the external effects device should not be
set to 100% wet (100% effect signal); otherwise, there will be no direct signal portion fed back
to the ULTRACOUSTIC.
48
The TAPE OUT provides a stereo copy of the ULTRACOUSTICs audio signal, e.g. for recording purposes.
The TAPE OUT is on RCA jacks.
49
The TAPE IN jacks perform the same function as the AUX IN. However, due to the RCA connectors you
can also connect a tape deck or hi-fi system directly to the TAPE IN jacks.
50
The AUX IN allows you to feed in additional stereo signals, for example, to play with a drum computer
or some sort of playback. Additionally, you can use the AUX IN in combination with the INSERT SEND
as a parallel effect path: connect the INSERT SEND to the input and the AUX IN to the output of the
effects device (INSERT RETURN jacks should not be used in this case!). Thus, the signal path inside
the amplifier will not be interrupted and you can add the effect portion from the external device, using the
AUX LEVEL control. Please note that the external effects device must be set to 100% wet for this
purpose.
This is the MIC INS. SEND jack of the microphone/line channels insert path. Connect this jack to the
input of an external effects device or compressor.
This is the MIC INS. RETURN jack of the microphone/line channels insert path. Connect this jack to
the output of an external effects device.
The instrument channel also features an insert path. This is the INSTR. INS. SEND jack.
The INSTR. INS. RETURN jack is used to feed back the effect signal to the ACX1000.
