PREAMP
(13) INPUT
The 5150 II input jack is designed to accommodate a variety of guitar output levels,
regardless of pickup configuration. Due to the extreme high gain capabilities of the 5150 II, it
is imperative that you use a premium shielded instrument cable in order to minimize noise.
(14) CHANNEL SELECT SWITCH
This switch allows selection of the Rhythm or Lead Channel. Depressing the switch to the “in”
position activates the Lead Channel. The red LED next to the Lead Pre control will illuminate
to indicate that the Lead Channel is active. In the “out” position, the Rhythm channel is
activated and the green LED illuminates next to the Rhythm Pre control to indicate that the
Rhythm Channel is active. Channels may be remotely selected using the 5150 II’s footswitch.
If remote selection is desired, the Channel Select Switch must be set to the “in” position
(Lead Channel). See page 9.
(15) CHANNEL SELECT LED
Both the Rhythm Channel and Lead Channel have these LEDs to indicate which channel is
active. The two Channel Select LEDs are never on at the same time. The channel with its
indicator illuminated is the active channel.
(16/20) PRE and POST GAIN
The channel Pre (16) and Post (20) Gain controls operate in the same manner for both
channels. However, the Lead channel does have more pregain than the Rhythm Channel. In
most applications, the Rhythm channel should be set up with the Pre Gain at the lower
“cleaner” settings (0-4) and the Post Gain should be set for overall volume. The Rhythm
channel can be converted to a medium distortion channel by activating the Crunch switch
(22). This will more closely match the pre gain of the two channels. The Lead channel should
be set up with the Pre Gain at the mid to upper settings (5-10) and the Post Gain should be
set for overall volume.
(17/18/19) EQUALIZATION
The 5150 II’s equalization block features passive low, mid, and high EQ that is custom
tailored for each channel to Edward Van Halen’s specifications. Adjusting the control(s)
counterclockwise will result in an attenuation of the signal within the frequency band.
(21) BRIGHT SWITCH
Activates a preset boost in the treble frequencies (6 dB at 2 kHz) and affects only the Rhythm
Channel.
(22) CRUNCH SELECT SWITCH
Boosts the gain of the Rhythm channel to create a medium distortion or in between tone.
Depress to the “in” position to activate.
(23/24) RESONANCE / PRESENCE
Unique to Peavey instrument amplifiers, the Resonance control (23) can be set to boost the
gain of the power amp in the low frequencies at the resonance/attenuation point of the
speaker cabinet. In simple terms, the Resonance control works like a low EQ to offset low-
end frequency drop out. The Presence control (24) works in the same manner, boosting the
high frequencies. Experimentation using your particular speaker cabinet, along with personal
taste, will determine your setting for these important controls.
