Use the POWER switch to put the ULTRACOUSTIC into operation.
FUSE HOLDER / VOLTAGE SELECTOR. Please make sure that your local voltage matches the voltage indicated on the unit, before you attempt to connect and operate the ULTRACOUSTIC. Blown fuses may only be replaced by fuses of the same type and rating. Some models allow for inserting the fuse holder in two different positions, in order to switch over from 230 V to 120 V operation, and vice versa. Please note that for 120 V operation outside Europe, you need a fuse of a higher rating (see chapter 3 “INSTALLATION”).
Use the enclosed power cord to connect the unit to the mains.
SERIAL NUMBER.
Connect the enclosed footswitch to the FOOTSWITCH jack. The footswitch allows you to recall the four effects presets.
MIDI IN. This connector gives you MIDI remote control over your ULTRACOUSTIC. You can change effects programs by means of program change commands.
The TUNER output always provides the instrument channel’s audio signal to feed an external tuner.
The balanced DIRECT OUT jack provides a
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.
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.
The TAPE OUT provides a stereo copy of the ULTRACOUSTIC’s audio signal, e.g. for recording purposes. The TAPE OUT is on RCA jacks.
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
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 channel’s 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 channel’s 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.
