Cooling. To ensure proper ventilation, there should be nothing placed on top of the unit. Ventilation holes should be unobstructed with at least 12” (300mm) of empty space above and around the unit. Turn-off when not using for prolonged periods of time. Due to a specific construction of the 250TL vacuum tube, the ELYSIUM amplifier can be left in the ON state for longer periods of time. However, due to the presence of high temperatures and high voltage, the amplifier should be turned off when not attended for longer periods of time. Also, it should not be left in the ON state overnight. Emergency shutdown. On the real panel ELYSIUM features an emergency shutdown switch (the “mushroom” switch). This switch is intended to be used only in case of severe tube arcing or other issues that warrant fast turn- off. Unlike the regular power switch which initiates turn off sequence which can last couple of minutes, depressing the “mushroom” switch will cut the power immediately, preventing more serious damage to the amplifier. When the emergency switch is activated, standard power switch should be turned off as well. After the problem has been re- solved (usually that means tube replacement), the switch is reactivated by turning it on clockwise for about quarter turn, at which point it will spring back. After that, regular on/off switch should be used to power on the unit.

MAINTENANCE Cleaning. Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a dry cloth for cleaning. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzene. Tube replacement. Vacuum tubes have life in the 10 000 hour range. We recommend replacing the tubes after 36 months, if necessary, depending on your listening habits. That will ensure that the unit always performs at its best and tube failure will not overstress other parts of the unit. Biasing the amplifier. Biasing of the ELYSIUM is not required. SERVICE Replacement Parts. When replacement parts are required, be sure that the service technician uses replacement parts specified by the manufacturer or parts with the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock or other hazards. Tube replacement. Should it become necessary to replace the vacuum tubes, remove the AC power plug from the wall and allow sixty minutes (60 min) for the tubes to cool down and high voltage capacitors to discharge. Follow instructions outlined below in the section “Handling vac- uum tubes”.
Carefully align the pins with the socket and gently insert the tube. Replace the protective cover before connecting ELYSIUM to the AC power. Never force a tube into a socket. Only the same type of vacuum tubes can be used – no substitutions are allowed. Should you decide to buy replacement tubes from Trafomatic Audio, rest assured that they were fully tested before the shipment. ELYSIUM - Single-Ended Mono Power Amplifier - User Manual...
PREPARATION FOR USE Place your unit on a flat, stable surface. Power switch, located on the rear side of the unit should be in the OFF position. Emergency switch (red “mushroom” switch) should be disengaged - to verify turn the button clockwise and make sure that it is in the “spring-back” position. Plug in the power cord. Connect audio source to one of the amplifier’s inputs. Make sure that volume control on your audio source is set to minimum position. Turn on the ELYSIUM by using ON/OFF power switch located on the rear side of the unit. Slowly increase volume, to make sure there are no unusual noises coming out of the speakers. CONGRATULATIONS! You are all set and ready to enjoy high sound quality of the ELYSIUM Mono Power Amplifier. ELYSIUM - Single-Ended Mono Power Amplifier - User Manual...
CONTROLS AND THEIR FUNCTIONS TOP PANEL The top panel of the ELYSIUM hosts the tubes and an instrument which measures bias current of the 250TL tube. After the amplifier warms up and reaches stable operating condition, the in- strument should read between 110 and 150mA ELYSIUM - Single-Ended Mono Power Amplifier - User Manual...
After that, regular on/off switch should be used to power on the unit. One balanced (XLR) input One unbalanced (RCA) input Speaker terminals, in form of five-way binding posts. There are three terminals, marked 0, 4 and 8 ohm. Speaker wire going to the negative speaker terminal should be connected to binding post marked with 0, while the positive terminal should be connected to the binding post with marking that corresponds to the nominal impedance of the speaker.
