ULTRAROC GX110
15
FUSE HOLDER/VOLTAGE SELECTOR. Please make sure that the voltage indicated on the unit,
matches your local voltage, before you attempt to connect and operate the ULTRAROC GX110. 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 115 V operation, and vice
versa. Please note that for 115 V operation outside Europe, you need to use a fuse of a higher rating
(see chapter 5 “INSTALLATION”).
16
Use the enclosed power cord to connect the unit to the mains.
17
MIDI IN. This connector gives you MIDI remote control over your ULTRAROC. You can change parameters
using controller information, switch over effect programs, change channels and bypass the effects
module by means of program change instructions.
18
SERIAL NUMBER. Please take the time to have the warranty card filled out completely by your
specialized dealer, and return it within 14 days after the date of purchase, so as to be entitled to benefit
from our extended warranty.
19
Use the LOUDSPEAKER jack to connect a supplementary speaker to your ULTRAROC. Optimum
adaptation is ensured with 8 Ω speakers. Inserting a plug into this jack will mute the built-in speaker.
20
The 1/4" jack PHONES allows you to monitor the ULTRAROC’s audio signal with a pair of commercially
available headphones. Connecting the headphones will mute the built-in speaker.
+ Since speakers can have quite an impact on the sound of a guitar amp, both the headphones
and LINE OUT signals are frequency-corrected (Speaker Emulation). Without this frequency
correction extreme treble frequencies would deteriorate the sound. You can still tap the
unprocessed signal directly after the pre-amp (INSERT SEND jack), without interrupting the
signal path in the amplifier (INSERT RETURN jack may not be used in this case). Starting with
a certain volume level, low-impedance headphones may begin to produce distortion. In such
a case, please reduce the volume by turning down the VOLUME controls.
21
The AUX TRIM control determines the volume of AUX signals fed into the ULTRAROC via the AUX IN
jacks on the rear (e.g. drum computer, playback).
22
The LINE OUT provides the ULTRAROC’s audio signal, for example, to send it to a recording machine.
This output is frequency-corrected (Speaker Emulation).
23
The AUX IN allows you to feed in additional 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 jack should not be used in this case!). Thus, the signal path in the amplifier
will not be interrupted and you can add the effect portion from the external device, using the AUX TRIM
control. Please note that the external effects device must be set to 100% wet for this purpose.
+ When you connect the INSERT SEND to the AUX IN using a short patch cord, you can add the
direct signal to the effect signal via analog circuitry. Advantage: The direct signal will be
provided all the time, even while the DSP is loading a new effects program. However, it
should be noted that all FX mixes in the presets should be set to higher values, so as to make
the effect signal heard.
+ Since the entire signal processing circuitry in the ULTRAROC is configured in mono, both the
LINE OUT and the headphones output provide the same signal on both (stereo) sides.
24
The ULTRAROC also features a serial insert path for external effects such as a compressor or wah-wah
pedal. This is the INSERT SEND jack you need to connect to the input of the effects device.
25
This is the INSERT RETURN jack that can be connected to the output of an external effects device.
+ Please note that when using the serial effects path, the external effect should not be set to
100% wet (100% effect signal); otherwise, there will be no direct signal portion fed back to the
ULTRAROC.
26
Connect the enclosed footswitch via its stereo plug to the FOOTSWITCH jack. The footswitch allows
you to change channels or disable the effects module.
