Peavey® 6505®II

Congratulations on your purchase of the all new 6505® II. Peavey's classic high-gain legacy continues with the 6505® II. Like the
original 6505 head, the 6505 II offers two channels. However, the 6505 II adds separate EQ, Resonance, and Presence controls
to each channel, giving you more control and flexibility. The new footswitch provides foot control of channel selection, effects
loop, and the newly added ability to select the Crunch feature. Now you can instantly obtain that extra gain in the Rhythm
Channel with your foot and never have to take your hand off the guitar. 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.

FEATURES:

• Two distinct tube channels with footswitch control

• LED “active” indicators for each channel

• Bright switch for Rhythm channel

• Crunch switch on Rhythm channel with footswitch control

• Separate equalizer sections for each channel

• Separate power amp controls (Resonance and Presence) for each channel

• Separate preamp controls (Pre and Post Gain) for each channel

• Standby power switch

• Bias test points on rear panel

• Effects loop with footswitch control

• 1/4" Preamp output jack

• Speaker impedance selection switch (4, 8, 16 ohm)

• Two parallel 1/4" speaker output jacks

• 120 watts output power ohm output power

• Metal three button footswitch with detachable 25' cable

VENTILATION: For proper ventilation, allow 24" clearance from the nearest combustible surface.

All vents should have a minimum of 2" of free air space so air can flow thru the unit freely for proper cooling.

(1) LINE CORD (120 V units only)

For your safety, we have incorporated a 3-wire line (mains) cable with proper grounding facilities. It is
not advisable to remove the ground pin under any circumstances. If it is necessary to use the 6505ii
without proper grounding facilities, suitable grounding adaptors should be used. Greatly reduced
shock hazard exists when the unit is operated with the proper grounded receptacles.

(2) FUSE
WARNING: THE FUSE SHOULD ONLY BE REPLACED WHEN THE POWER CORD
HAS BEEN DISCONNECTED FROM ITS POWER SOURCE. A 5 amp fuse is located within the cap of the fuse
holder. It must be replaced with the same type and value in order to avoid damage to the equipment
and to prevent voiding the warranty. If the amp repeatedly blows fuses, it should be taken to a
qualied service center for repair.

(3) GROUND SWITCH
This is a three-position, rocker type switch which, for most applications, should be operated in
the center (zero) position. If hum or noise is noticed coming from the speaker enclosure(s) with
the Ground Switch in the center position, place the Ground Switch to positive (+) or negative (-)
to minimize hum. Should a hum/noise problem continue, consult your authorized Peavey dealer, the
Peavey factory, or a qualied service technician.

(4) BIAS TEST TERMINAL
These terminals, along with the adjustment knob behind the grill are provided to measure and adjust
the power amp tubes’ bias. The bias adjustment should only be done by a
alied technician.

(5) EFFECTS SEND/EFFECTS RETURN
Signals are supplied to outboard eects or signal processing units by patching from the Eects
Send output into the outboard unit(s) and back into the Eects Return input using shielded
cables with 1/4" mono phone plugs. Only non-gain eects devices (chorus, reverb, delay, etc.)
should be used in the eects loop. If footswitch is used, “Eects” must be selected (LED
illuminated) for eects to work.

(6) PREAMP OUT
This output can be used to send a preamp signal from the 6505 II to a mixing console, tape
recorder, etc., using a shielded instrument cable. Patching from the PREAMP OUT does not aect the
normal operation of the amplier.

(7) REMOTE FOOTSWITCH JACK
This jack is provided for the connection of the supplied remote footswitch. The footswitch cable
should be plugged in before the amp is powered up. When the footswitch is plugged into the Remote
Footswitch Jack, the Channel Select switch (14) must be pressed to the “in” position for remote
selection of the Lead or Rhythm channel (right footswitch button). The On and O operation of
Eects (left footswitch button) will work at all times. Remote selection of Crunch gain boost
(center footswitch button) is available only when the Crunch Switch (22) is selected. See page 9
for detailed Footswitch diagram.

(8) SPEAKER JACKS
These jacks are provided for the connection of speaker enclosure(s). The minimum speaker
impedance is 4 ohms. The Impedance Selector Switch (5) should be set accordingly.

(9) IMPEDANCE SELECTOR SWITCH (5)
Use this switch to select the appropriate impedance of the speaker enclosure(s) connected to
the Speaker Jacks (4). If two enclosures of equal impedance are used, the switch should be
set at one half of that value (e.g., two 16 ohm enclosures: set switch to 8 ohms; two 8 ohm
enclosures: set switch to 4 ohms).

STANDBY

(10) POWER SWITCH/LED
This switch supplies power to the unit. Depressed to the “ON” position, the red Power LED indicator
will illuminate above the Power Switch when power is being supplied to the unit.

(11) STANDBY SWITCH/LED
This switch allows the 6505 II to be placed in a non-operational standby mode. 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.

(12) INPUT
The 6505 II input jack is designed to accommodate a variety of guitar output levels, regardless of
pickup conguration. Due to the extreme high gain capabilities of the 6505 II, it is imperative
that you use a premium shielded instrument cable in order to minimize noise.

ONON

POWER

(13) 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 6505 II’s footswitch. If remote selection is
desired, the Channel Select Switch must be set to the “in” position (Lead Channel).

(14) 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.

(15/18) PRE and POST GAIN
The channel Pre (15) and Post (18) 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 (17). 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.

(19/20/21) EQUALIZATION
The 6505 II’s equalization block features passive low, mid, and high EQ that is custom tailored for
each channel to classic Peavey specications. Adjusting the control(s) counterclockwise will
result in an attenuation of the signal within the frequency band.

(16) BRIGHT SWITCH
Activates a preset boost in the treble frequencies (6 dB at 2 kHz) and aects only the Rhythm
Channel.

(17) 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.

(22/2) RESONANCE / PRESENCE
Unique to Peavey instrument ampliers, the Resonance control (22) 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 oset low- end frequency drop out. The
Presence control (23) 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.
