Frequently Asked Questions - 6505 1992 Original PEAVEY

How do I switch between the Lead and Rhythm channels?

Use the Channel Select switch on the front panel. Depress to 'in' for Lead (red LED), 'out' for Rhythm (green LED). Alternatively, use the included footswitch; ensure the front panel switch is set to 'in' for remote operation.

What is the difference between the High and Normal inputs?

The High input has twice the gain of the Normal input, suitable for maximum overdrive. When both inputs are used simultaneously, the amp automatically applies a 6 dB pad (normal gain mode). Use the Normal input for cleaner sounds.

How do I set up the effects loop?

Connect the Effects Send (output) to the input of your non-gain effects device (e.g., delay, reverb, chorus), and return the signal to the Effects Return. Use shielded 1/4" cables. Only non-gain effects should be used in the loop. The footswitch can bypass the loop remotely.

What does the Crunch switch do?

The Crunch switch boosts the gain of the Rhythm channel, effectively turning it into a second lead channel with higher distortion. Depress the switch 'in' to activate.

How do I properly connect speaker cabinets?

Use unshielded speaker cables. Connect to the two parallel 1/4" Output jacks. Set the Impedance Selector switch to match the total impedance: for a single cabinet, set to its impedance; for two cabinets of equal impedance, set to half that value (e.g., two 16-ohm cabs = 8 ohms). Minimum total impedance is 4 ohms.

What is the purpose of the Standby switch?

The Standby switch allows you to mute the amplifier while keeping the tubes hot and ready. Use it during breaks to avoid warm-up time. The white LED illuminates when the amp is in operational mode (Standby off). Always turn Standby on before powering off.

Can I use the Preamp Out to record?

Yes, the Preamp Out sends a preamp signal to a mixing console or tape recorder. It does not affect the amp's normal operation. Use a shielded cable with a 1/4" jack.

What type of tubes does the 6505 1992 Original use?

The manual references tube stages but does not specify exact tube types. Typically, the 6505 series uses four 12AX7 preamp tubes and four 6L6 power amp tubes. Refer to the official Peavey service documentation for precise details.

How do I reduce hum or noise?

Use the Ground switch on the rear panel: try center (zero) first, then flip to + or - to minimize hum. Also ensure proper grounding of the AC outlet. If hum persists, consult an authorized Peavey dealer or technician.

What is the warranty and where can I register?

Warranty registration for US customers is available online at www.peavey.com/warranty. Features and specifications are subject to change without notice. For non-US customers, contact your local Peavey distributor.

SPEAKER CONNECTION

When connecting the amplifier to the speaker enclosure, make sure to set the impedance selector switch on the rear of the unit to the impedance that matches your enclosure. When two enclosures of equal impedance are used, set the switch to one half the impedance of one enclosure (e.g. two 16 ohm enclosures: set switch to 8 ohms; two 8 ohm enclosures: set switch to 4 ohms). The 6505 1992 Original is designed to operate into a minimum of 4 ohms.

OPERATING GUIDE

1 INPUTS The 6505 1992 Original's input block features HIGH [1] and NORMAL [2] gain inputs. The HIGH gain input has twice the gain of the NORMAL gain input and should be used when maximum overdrive is desired. When both inputs are used simultaneously, the 6505 1992 Original automatically switches the normal gain mode (6 dB pad). Situations where both inputs are used at once (alternating between two guitars on stage using both inputs, etc.) should be avoided if peak overdrive is expected from the amp. Experimentation with your particular guitar/pickup into each input will determine which input is best for your sound.
3 CHANNEL SELECT SWITCH Allows selection of the RHYTHM or LEAD channel. Depressing the switch to the "in" position activates the LEAD channel. The red LED light will illuminate to indicate that the LEAD channel is active. In the "out" position the RHYTHM channel is activated and the green LED illuminates. Channels may be remotely selected using the 6505 1992 Original's footswitch. If remote selection is desired the channel select switch must be set to the "in" position (LEAD channel).
8 LEAD PRE & POST GAIN The LEAD CHANNEL PRE GAIN [8] controls the input level and works with the LEAD CHANNEL POST GAIN [13] to determine the overall volume/overdrive of the LEAD channel. Lower settings of the PRE GAIN control produce a relatively clean, undistorted sound while the middle to high settings produce harmonically rich distortion and screaming
overdrive/sustain. Since both PRE and POST GAIN controls work in "combo" a basic rule-of-thumb set-up procedure is to begin with both controls in the lower settings (0 - 2). Using the PRE GAIN control, dial in the amount of overdrive/sustain you want for the LEAD channel. Then, with the POST GAIN control adjust for overall volume.
4 RHYTHM PRE & POST GAIN The RHYTHM channel PRE [4] and POST GAIN [12] operate in the same manner as the LEAD channel gain controls. For most applications, the RHYTHM channel should be set up with the PRE GAIN at the lower, "cleaner" settings (0 - 4) and the POST GAIN set for overall volume. The RHYTHM channel can be converted to a second "lead" channel by activating the CRUNCH SWITCH [6].
5 BRIGHT SWITCH Activates a preset boost in the treble frequencies (6 dB at 2 kHz) and affects only the rhythm channel.
6 CRUNCH SELECT SWITCH Boosts the gain of the rhythm channel to create a second "lead" channel. Depress to the "in" position to activate.
9 EQUALIZATION The 6505 1992 Original's 0 equalization block features passive LOW, MID, and HIGH EQ. 1 4 RESONANCE I PRESENCE Unique to the 6505 1992 Original, the RESONANCE [14] control can be set to boost the gain of the power amp in the low frequencies
overdrive/sustain. Since both PRE and POST GAIN controls work in "combo" a basic rule-of-thumb set-up procedure is to begin with both controls in the lower settings (0 - 2). Using the PRE GAIN control, dial in the amount of overdrive/sustain you want for the LEAD channel. Then, with the POST GAIN control adjust for overall volume.

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 [15] control 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.

18 STANDBY SWITCH Allows the 6505 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 light [16] will illuminate when the amp is in the operational mode.
19 POWER SWITCH Supplies power to the unit. Depressed to the "ON" position, the POWER LED indicator light [17] will illuminate indicating power is being supplied to the unit.
20 FUSE 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 qualified service center for repair. WARNING: The fuse should only be replaced when the power cord has been disconnected from its power source.

power source.
21 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 6505 1992 Original 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.
22 GROUND SWITCH 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 (+or -) to minimize hum. Should a hum/ noise problem continue, consult your authorized Peavey Dealer, the Peavey factory, or a qualified service technician. NOTE: The ground switch is not functional on 220/240 volt models.

23 EFFECTS SEND I EFFECTS

RETURN

24 Signals are supplied to outboard effects or signal processing units by patching from the EFFECTS SEND [23] output into the outboard unit(s) and back into the EFFECTS RETURN [24] input using shielded cable with 1/4" phono jacks. Only non gain effects devices (chorus, reverb, delay, etc.) should be used in the effects loop. Remote (on/off) selection of outboard effects devices can be achieved using the 6505 1992 Original's footswitch.

25 PREAMP OUT

This output can be used to send a preamped signal from the 6505 1992 Original to a mixing console, tape recorder, etc., using shielded cable. Patching from the PREAMP OUT does not affect the normal operation of the amplifier.

26 REMOTE FOOTSWITCH JACK

Provided for the connection of the supplied remote footswitch. When the footswitch is plugged into the remote footswitch jack, the channel select switch [3] must be pressed to the "in" position for remote selection to operate. Remote selection of the LEAD or RHYTHM channel (left footswitch button) or outboard devices in the effects loop (right footswitch button) is possible with the remote footswitch.

SPEAKER OUTPUTS

Paralleled 14 " OUTPUTS output jacks for connecting speaker enclosure(s) to the amplifier (minimum: 4 ohms). When using more than one enclosure, be sure to calculate the total impedance and set the impedance switch [28] accordingly. (See section on IMPEDANCE SWITCH.) Important: Use only high quality, Unshielded cable for speaker connections.

IMPEDANCE SELECTOR

SWITCH Use to select the appropriate impedance of the speaker enclosure(s). 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).
