18) Jeweled Pilot Light—Indicates that the amplifier’s power switch is in the “On” position. 19) On/Off Power—Provides AC power to the amplifier when in the “On” position— switched to the left. 20) Standby—This allows the amplifier to be powered up, but with the tubes in a non-operational mode. The Standby can be used instead of the power switch between performance sets, since it allows the amp to “shut down” while keeping the tubes warm and ready to go. It’s also best to power the amp up with this switch set to the right/off position until the tubes have had a few minutes to warm up, although modern tubes are more tolerant of this. V100 Back Panel 1234 5 1) Footswitch Assignment—This button selects which of the amp’s effects are controlled by the “Effects” button on the footswitch. If the switch is IN, the foot- switch will control the Reverb and the Tremolo will only be controlled by the Pull Active Switch on the Speed control. If the Footswitch Assignment button is OUT, then the Reverb will be active always, and the footswitch will remotely control the Tremolo/Vibrato, overriding the setting of the Pull Active Switch on the Speed control. 2) Footswitch—The Footswitch jack on the V100 is a stereo jack that connects the V100 footswitch to the amplifier. It uses a special circuit to decode the 3 switches through a simple stereo cable. In an emergency, a mono instrument cable can be used to allow footswitching of the channels only. In this setup, the LEDs will not be visible, but at least the footswitch will select Rhythm or Lead channels. 3) Ground Lift—The Ground Lift switch disconnects pin 1 of the XLR Direct Out jack to eliminate a “ground loop” hum. A ground loop can exist when the V100 and the mixer it is plugged into are connected to grounded outlets that are in physically different locations and/or on different circuits, and should only be used if there is an audible hum. Pressing the ground lift does not disconnect the ground connection from the V100’s chassis. 4) Direct Out—The XLR Direct Out jack is designed to connect the V100 amplifier to a recording or live mixer. The output is speaker-emulated, and mimics the sound of the Celestion Vintage 30 loudspeaker. This output is very useful for direct recording, and especially helpful for live applications since it eliminates a live mi 678 crophone on stage and the resulting feedback potential. The V100 amplifier should never be operated without a speaker plugged into a speaker jack. 5) Direct Volume—Sets the level of the speaker-emulated direct out. This control should be set as high as possible for the best signal-to-noise ratio. 6) Boost Volume—The Boost Volume knob controls the amount of footswitchable boost, and is particularly useful for solos. It will provide up to 10dB of “Master Volume” boost, and boosts both channels. The tone is optimized to increase the volume without sacrificing too much headroom in the power amp, so the resulting solo cuts through. The boost is active if the footswitch is unplugged. 7) Effects Return—This 1.4” jack breaks the flow of amplifier signal to allow an external effects device to “return” to the amp. The Return jack can also be used for a power amp input, when using an external preamp. This all-tube effects loop is known as a “series” loop, since it breaks the path of the amplifier and “inserts” the effect in series. 8) Effects Send—This 1.4” jack delivers a tube-driven preamp signal to external effects devices. It can be used to send the signal to another amplifier to run multiple amps. Connecting a 1.4” plug does NOT break the flow of the amplifier signal. To connect two Defender amplifiers in stereo, a stereo effects device can be driven from one Defender amp’s Send, and the device’s two stereo outputs can be returned to both Defender amp Returns. .. ..

EL34EL34EL34EL3410040 1) Power Cord Receptacle/Fuse Holder: Insert the AC cord (provided) firmly into the AC connector. NOTE: Replace the AC power cord if protective jacket is damaged or ground pin is damaged or removed. The fuse is located in a housing just below the receptacle. Replace only with same type and size. To remove the fuse, remove AC power cord and pull out on the tab above the fuse symbol located on the fuse carriage. Place the new fuse in the carriage clip and re-insert. NOTE: To prevent an electrical hazard, DO NOT replace fuse without using the fuse carriage. Replace the fuse carriage if lost or damaged before re-inserting the AC power cord. 2 & 3) Speaker Outputs—These 1.4” jacks are provided to connect the internal and/or external speakers to the V100 amplifier. The V100 amplifier should never be operated without a speaker plugged into a speaker jack. 4) Impedance Selector—This switch is used to sel...
