User manual PEAVEY 5150 II

[. . . ] Finally, the Clean Channel has been added, completely redesigned to sound much cleaner, and has one 12AX7 devoted to just the Clean/Crunch. The following guide explains these features and how to operate each one in order to obtain your desired sound. We recommend that you read this manual carefully, paying close attention to any warnings or cautions. Two distinct tube channels with footswitch control · Separate power amp controls (Resonance and Presence) for each channel · 120 watts output power ohm output power · Metal three button footswitch with detachable 25' cable (1) LINE CORD: This line cord provides the AC power to the unit. [. . . ] When the Standby Switch is activated, the tubes remain hot and ready for instantaneous operation, eliminating warm-up time. The Standby LED indicator above the switch will illuminate when the amp is in the operational mode. 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. 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. 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. 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. CRUNCH SELECT SWITCH Boosts the gain of the Rhythm channel to create a medium distortion or in between tone. (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 lowend 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. The following specs are measured @ 1 kHz with the controls preset as follows: Low and High EQ @ 10 Mid EQ @ 0 Bright out Lead and Rhythm Posts @ 10 Presence and Resonance @ 0 dB Nominal levels with Pre Gains @ 5 Minimum levels with Pre Gains @ 10 (Typically @ 5% THD, 1 kHz, 120 V AC line) 130 W RMS into 16, 8, or 4 ohms (Bias must be reduced to measure. Special 3-button unit with LED indicators (supplied) Channel select and reverb (20 Hz to 20 kHz unweighted) Greater than 63 dB below rated power Greater than 75 dB below rated power Features and specifications subject to change without notice. [. . . ] Servicing is required when the apparatus has been damaged in any way, such as powersupply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. If this product is to be mounted in an equipment rack, rear support should be provided. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time. [. . . ]
