Connecting a tape or CD recorder to the Hera

Phono (for an external phono preamp), CD, Tuner, and AUX 1. There is also one pair of Balanced XLR inputs.

Connecting the Hera to multi channel sources using the Unity Gain Input: The Hera features a unity gain bypass allowing you to integrate your two channel music systems into a multichannel home theater system. This conveniently enables you to share speakers and amps between systems without switching interconnect or speaker cables. In this configuration the Hera is then used with two channel sources such as CD Players, turntables, tuners etc, while a separate processor or multi channel receiver is used with multichannel sources such as DVD movies. Simply connect the left and right front outputs from your processor to the unity gain inputs on the Hera. These inputs route the home theater signal directly to the power amp completely bypassing the active circuitry in the Hera. To activate this unity gain input, the bypass switch on the front of the preamplifier must be pushed in (see Figure 3). Once this switch is on, all other inputs are deactivated and the preamplifier is in bypass mode. Note that if the preamplifier is turned off it automatically goes into bypass mode.

Connecting an audio processor to the Hera:

The Hera features a processor loop which allows processors (equalizer, room correction, bass enhancement, etc.. ) to be used. There are two sets of RCA jacks on the rear of the preamp for connecting to/from a processor. When the processor button is pushed in a blue LED below the button will light indicating that the source signal is going through the processor. With the button out the signal bypasses the processor. Note that if no processor is connected and the button is pushed in then the signal is interrupted and there will be no output from the preamplifier.

Connecting a tape or CD recorder to the Hera:

The Hera features a buffered tape loop and tape monitor for recording from other sources and for monitoring the recording as it is being made. The buffered tape output prevents “loading down” of the preamp by the recording equipment thus providing a higher level of fidelity in the recording process as well as the monitored playback. Connect the output jacks from the recording device to the “Tape In” jacks on the back of the Hera. Connect the “Tape Out” jacks on the Hera to the input jacks of the recording device. Note that if the Tape Monitor button is pushed in on the Hera that the source will be the output from the recording device.

Connecting the Hera to the power amplifier:

There are two RCA outputs and two Balanced XLR outputs. These are used to connect the Preamplifier to the Power Amplifier in your system. Note that the output in balanced mode is 3dB higher than for single ended mode.

Connecting a subwoofer to the Hera:

A second set of both RCA and XLR outputs are provided that can be used for connecting a subwoofer to the Hera. The signal to these outputs is identical to the signal going to the power amp and varies with the volume control. Note that these outputs can also be used for biamping or running a second power amp located elsewhere.

Hera specifications

Rogue Audio has established itself as a prominent name in the world of high-fidelity audio, and the Hera preamplifier is a testament to its commitment to quality and performance. The Hera preamplifier is designed for audiophiles seeking a perfect blend of modern technology and classic engineering principles.

One of the standout features of the Hera is its dual-mono construction, which ensures that each channel operates independently. This design minimizes crosstalk and enhances soundstage depth, delivering a more immersive listening experience. Equipped with a wide range of inputs, the Hera accommodates virtually any source component. It integrates seamlessly with digital and analog equipment, including turntables, CD players, and streaming devices.

The Hera’s sound is characterized by remarkable clarity, detail, and dynamic range — hallmark traits of high-end audio gear. This is achieved through Rogue Audio's innovative circuitry, which has been meticulously engineered to minimize signal degradation. 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.
