37 POWER TUBE FUSE
Fuse (refer to the description of the E.C.S. on page 10) for the left power tube (the far left tube
when viewed from the rear of the chassis); the LED above the fuse illuminates when this fuse is blown.
Replacement fuses (160 mAM) are located at the housing´s rear panel.
38 POWER TUBE FUSE
Fuse for the second power tube (second from left);
the LED above the fuse illuminates when this fuse is blown.
Replacement fuses (160 mAM) are located at the housing´s rear panel.
39 POWER TUBE FUSE
Fuse for the third power tube (second from right);
the LED above the fuse illuminates when this fuse is blown.
Replacement fuses (160 mAM) are located at the housing´s rear panel.
40 POWER TUBE FUSE
Fuse for the right power tube (the far right tube);
the LED above the fuse illuminates when this fuse is blown.
Replacement fuses (160 mAM) are located at the housing´s rear panel.
41 LEVEL
Signal level control for the frequency-corrected line output; it is used to match
the amp’s signal level at the LINE output to the mixing console or recorder’s input.
42 OVERLOAD
This LED denotes the LINE output is overloading; in this case,
reduce the signal’s level via the LEVEL control.
43 FREQU.-COMPENSATED LINE OUT (BALANCED) .................................................
TIP 9
The frequency-corrected, balanced LINE output jack (XLR). (Pin 2 and 3 signal, Pin 1 = N.C. ).
Its signal simulates a 4 x 12" speaker cabinet.
44/45 POWERAMP OUTPUT: 4 OHM
4 ohms speaker output jacks; internal paralell signal path for the connection of one 4 ohms
or two 8 ohms cabinets (unplug the internal speaker before connecting an external cabinet!).
46/47 POWERAMP OUTPUT: 8 OHM
8 ohms speaker output jacks; internal paralell signal path for the connection of one 8 ohms
or two 16 ohms cabinets (unplug the internal speaker before connecting an external cabinet!).
48 POWERAMP OUTPUT: 16 OHM
Speaker output jack for the internal speakers or, alternatively you can connect
an external 16 ohms speaker cabinet.
NOTE:
Never operate the amplifier without a sufficient load, otherwise you may
damage or destroy the power amp! Ensure your cabinet’s specifications match the
respective output’s specs.
Choose only one
of the following cabinet options:
A.
One 4 ohms cabinet connected to a 4 ohms jack (without the internal speakers!)
B.
Two 8 ohms cabinets connected to the 4 ohms jacks (without the internal speakers!)
C.
One 8 ohms cabinet connected to a 8 ohms jack (without the internal speakers!)
D.
Two 16 ohms cabinets connected to the 8 ohms jacks (without the internal speakers!),
or an external 16 ohms cabinet and the internal speakers connected to the 8 ohms jacks.
When you unplug the cable for the external cabinet, ensure you plug the internal speakers
back into the 16 ohms jack!
E.
Internal speakers only or an external 16 ohms cabinet to the 16 ohms jack only.
