INTRODUCTION Congratulations on your purchase decision! We at Rogue Audio truly believe that our amplifiers provide the “smartest” value in high-end audio. If you have never owned a vacuum tube amplifier you will be thrilled by the silky-smooth sound and incredible detail that only a tube amplifier can provide. And with the Zeus amplifier, you can be sure that you are getting the very best in tube amplification.
CONNECTING ZEUS TO YOUR SYSTEM Connecting Zeus to the Loudspeakers: The rear panel has binding posts for both 4 and 8 ohm loudspeakers. The 4 ohm taps are those located closest to the center of the amps rear panel. The 8 ohm taps are located nearest the sides of the rear panel. In general, if your speakers are rated at less than 6 ohms, use the 4 ohm taps and use the 8 ohm taps if they are 6 ohms or greater.
Connecting Zeus to the power outlet: Your Zeus amplifier has been provided with a high ampacity power cord. Use this cord to connect the amplifier to the wall outlet. It is recommended that you use the same outlet as the preamp to avoid creating a ground loop. It is also recommended that you do not use a power conditioner as it may limit the current available to the amplifier. OPERATION OF THE AMPLIFIER After all proper connections have been made, you are now ready to turn the Zeus amplifier on.
level in triode is high enough that it will likely provide plenty of power for almost any speaker load. 3) Ultralinear operation – With this configuration, power levels near those of tetrode mode are achieved with low distortion levels that approach those of triode operation. For loudspeakers that demand very high levels of power, ultralinear should provide excellent sound and plenty of power. The triode/ultralinear switch allows the user to operate Zeus in either of the two modes.

Turn the preamplifier off so that no signal is entering the amplifier Loosen the 4 captive screws on the top hatch cover. Remove the hatch cover. The bias tool is snap attached to the inside of the cover. 5) Locate the toggle switches and associated small potentiometers (they are blue and have a small screw in the top). There is a set of six for each of the left and right channels.

Bias switches and potentiometers 8) Flip the switch towards the rear of the amp thus disengaging the tube from the meter circuit. 9) Repeat the above steps for each of the tubes in both channels. As it is a quick operation, the tube bias should be checked on a regular basis. TROUBLESHOOTING Speaker Hum – If hum can be heard from more than a few inches from the loudspeaker, there is probably a ground loop. Try using the “low Z” RCA jacks.
