OPERATION OF THE PREAMPLIFIER

Powering up the System:

After all proper connections have been made, you are now ready to turn the Hera preamplifier on. The power on/off switch is on the front of the power supply. The Hera employs an automated sequential soft-starting mode to prolong tube life as well as to suppress turn-on transients. When the unit is first turned on, the tube heaters are energized. After approximately twenty seconds, the high voltage supply is turned on and after and additional twenty seconds the outputs are disconnected from ground and the preamp is ready for operation. After turning on the preamplifier, turn on the power amplifier and source material and you are ready for listening. Note that critical portions of the Hera remain energized even with the power button in the off position. The first time that the Hera is turned on (and anytime it is unplugged from the power outlet) it is best to let it idle for a few minutes before playing music. This allows these portions of the circuitry to reach optimum operating parameters.

NOTE - This unit will not play for approximately 40-60 seconds after power on while the preamp goes through its sequential start-up.

The preamplifier utilizes a combination of high-quality capacitors, resistors, and a specially designed power supply to ensure that the audio signal remains pure.

Another noteworthy aspect of the Hera is its tube-based design. By utilizing 12AX7 tubes in its signal path, the preamplifier can deliver the warmth and richness that many audiophiles desire while maintaining a fast response time and accurate sound reproduction. The tubes can be easily accessed for rolling, allowing users to tailor their sound to their preferences, making the Hera more than just a standard preamp.

The Hera also features a robust, metal chassis that provides superior shielding against electromagnetic interference. This enhances overall sound quality and adds to the longevity of the unit. Its minimalist aesthetic, complete with a clear and intuitive front panel, makes it an attractive addition to any audio system.

In conclusion, the Rogue Audio Hera preamplifier combines advanced technology with classic audio design, offering exceptional sound quality and versatility. With its dual-mono architecture, extensive input options, tube-driven circuitry, and durable construction, it stands as a top contender for anyone serious about experiencing high-fidelity audio. Whether you are listening to your favorite vinyl or streaming high-resolution files, the Hera promises to elevate your listening experience to new heights.
