OPEN CARTON - UNPACKING THE VULCAN To avoid damaging the vacuum tubes please don’t turn the cardboard box upside down. Open the box and carefully take out the vacuum tubes and then the amplifier.
OPERATION 1. Installing the vacuum tubes Please remove the vacuum tubes and the Vulcan from box and place the Vulcan on a firm, level surface. Insert the vacuum tubes in accordance with the designated tube numbers into their relative assigned sockets. Note: It is very important to insert the tubes in the correct location. Important: Pay close attention to the direction of socket pins. If the direction is wrong and you force the tube, damage to the socket pins will occur.

Plug the AC power cord into receptacle. Power switch off = “0” - Power switch on = “|”.
3. Turn ON procedure When all sources are connected properly, turn down the volume (preamp) to minimum, switch on the power - the Ayon-logo glows; it will go through a gentle power-on sequence first. Please wait for min. 60 seconds before turning the volume up. After 60 seconds, the unit is operational. Now you can increase the volume. Follow this procedure each time you turn your Vulcan on. Some preamplifiers and sources can generate dangerous transients that can damage loudspeakers.
Note: NEVER REMOVE THE BOTTOM PLATE OF THE VULCAN BEFORE UNPLUGGING THE UNIT FROM THE WALL! 6. Grounding Make sure that Vulcan monoblock’s are grounded to your wall ground first. If there is a hum loop (hum audible from more than a few inches from the loudspeakers) flip the grounded/ungrounded switch. If the hum doesn’t disappear then use a two prong plug to “float” one monoblock first and if it is necessary then “float” the second one too.
bias adjustment 9. Power tube – protection board In order to protect the output level to the tubes, this unit is equipped with a special protection power tube circuit to detect over currents and voltages. When an over current or DC-input from the sources is detected or a power tube itself has a problem, the protection circuit will shut off the output tube’s current and continue to do so until the power is switched off.
BREAK-IN PERIOD Your new Ayon Audio electronics Vulcan tube amplifier has an initial break–in period. The unit will not perform to its full sonic potential when first installed in your system. This is partially due to a residual polarization of the dielectric materials used in the PCB, like resistors, capacitors, chokes, transformers and internal wiring. As music is played through the unit, the electrical signal will gradually anneal these materials.
WARRANTY AND SERVICE LIMITED WARRANTY Ayon Audio electronic components are warranted by the manufacturer to be free of defects in materials production for a period of 3 years (except all kinds of signal, rectifier and power tubes) from the date of purchase. Under this warranty defects are repaired free of charge. The purchaser is responsible for transportation from his location to the original sales agent, national distributor, or international distributor, whoever is closest.
