Genz-Benz EL DIABLO 60 Musical Instrument Amplifier User Manual


 
5. EFFECTS LOOP – The EL DIABLO is designed with a serial effects loop. The effects loop is a post master
section loop and is an ideal place to send the entire preamp signal out to another amp using only the send jack, or to
insert a global effect such as a compressor (serial effect) or a digital effects processor (a serial effect when used with
the processor’s own “wet/dry” mix control). The return is also a handy input for connecting the power amp stage to
the output of another preamp or signal source.
6. LINE OUTPUT – This ¼” jack provides an unbalanced signal that is derived after the power amplifi er and
output transformer. This line level output is ideal for driving a powered speaker that requires a line level input, or for
driving an additional instrument amplifi er that requires an instrument level signal. This signal is frequency compen-
sated to emulate the same tone coming through the amplifi ers speaker cabinet.
7. SPEAKER OUTPUTS – These parallel speaker jacks are provided for connecting to the guitar cabinet of
choice. It is important to become familiar with using the impedance selector switch and impedance calculator so that
the proper cabinet impedance is selected for the safe and effi cient operation of this high output tube amplifi er. Note:
The El Diablo 60 combo version comes loaded with an 8-ohm loudspeaker.
WARNINGS:
• NEVER UNPLUG THE SPEAKER CABLE FROM THE GUITAR CABINET WHEN THE AMP IS ON!!!
• DO NOT OPERATE THIS AMP WITHOUT A SPEAKER LOAD PLUGGED INTO ONE OF THE SPEAKER
JACKS.
• THE DIABLO OFFERS SOME PROTECTION AGAINST THIS DAMAGE BUT IT IS NEVER A GOOD IDEA TO
OPERATE ANY TUBE AMP WITHOUT A SPEAKER LOAD ATTACHED.
8. IMPEDANCE SELECTOR SWITCH – This 3 position switch is designed to easily select the appropriate
output transformer impedance tap for the desired cabinet load being used. A 16 ohm, 8 ohm and 4 ohm position is
offered. It is important to know the total impedance of the guitar cabinets being used with your amp. It is
important for amplifi er performance, tube life and output transformer protection to select the correct impedance for
your chosen guitar cabinet. Consult the rear panel impedance calculator for this information.
9. IMPEDANCE CALCULATOR – As part of making the GENZ BENZ EL DIABLO 60 both user- friendly and
convenient to use, we have included a comprehensive impedance chart so that this information is always accessible
to the user.
10. PENTODE 60/TRIODE 30 POWER MODE – This switch easily and safely reduces the output power
of the amp from 60 watts to 30 watts by changing the parameters by which the power tubes function—Pentode or
Triode. In the 60-watt PENTODE MODE the amp responds with its “spanky”, rich Clean tone and Classic overdrive
sustain, all the way into aggressive Hi Gain brutality and all points in between. In the 30-watt TRIODE MODE the
El Diablo 60 produces a more vintage, fuller, fatter tone with a more dynamic response and increased power tube
break-up with a darker complexity.
