MAINS CONNECTION. Use the power cord supplied with the unit to connect
it to the mains.
(16)
FUSE HOLDER/VOLTAGE SELECTOR. Before connecting the unit to the
mains, make sure that the voltage setting matches your local voltage.
A blown fuse should only be replaced by a fuse of the same type and rating.
On some units, the fuse holder can be switched to one of two positions,
i.e. 230 V and 120 V. When operating the unit outside Europe at 120 V,
a higher fuse rating is required.
(17)
The GROUND LIFT switch disconnects (switch pressed) the ground
connection at the LINE OUT output to effectively eliminate hum noise
resulting from ground loops (K3000FX and K1800FX only).
(18)
Use the balanced LINE OUT XLR connectors to feed the audio signal from
your ULTRATONE to a mixing console (K3000FX and K1800FX only). The LINE
OUT signal is post-EQ.
(19)
These are the LINE OUT outputs on 1/4" TS connectors (K900FX and K450FX:
one 1/4" TS connector).
◊
Both XLR and 1/4" TS LINE OUT connectors can be used simultaneously.
(20)
For stereo operation the ULTRATONE features a STEREO LINK facility.
You can connect the OUT of the ULTRATONE to the LINK IN of another
keyboard amp that serves as slave to achieve true stereo sound. When using
the ULTRATONE as slave, connect the LINK OUT of the master amp to the IN
(K3000FX and K1800FX only).
(21)
The SUB OUT connector provides the line-level mono subwoofer signal for
connection to the input of a power amp or active subwoofer.
(22)
Connect your footswitch to the FOOT SW jack, so as to activate/deactivate
the effects processor.
(23)
Use the CD IN (K900FX and K450FX: AUX IN) connectors to connect the
output of your CD player, tape deck, CD or MD walkman. This way you can
play along to music or keyboard tutorial CDs.
(24)
These are the LINE inputs for channels 1 - 4 on 1/4" TS connectors. For mono
input signals please use the L (MONO) connector.
(25)
Channel 1 is equipped with an additional XLR MIC input. Due to internal
+15 V phantom power you can even use condenser microphones. Both XLR
and 1/4" TS connectors can be used simultaneously. In this case the LEVEL
control of channel 1 adjusts both the level of the LINE and MIC signal.
