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.
