The preamplifier completes the Classic line by it high quality components used for the volume control feature. It has been thought in order to give a lot of different signal routings. You can use it as a stereo or a multichannel preamplifier. Moreover this product offers a wide range of inputs and outputs.
Ingenious software programming permits the user to quickly re-assign one or two sets of three stereo inputs to operate as a six-channel input. Similarly, multiple stereo outputs can be re-configured as a single six-channel output.
The Orpheus engineering team has created a unique high-end two-channel preamplifier that offers multichannel flexibility at no sacrifice in absolute performance. The future-proof Orpheus Preamplifier can be re-configured to suit your changing needs quickly and easily. At full scale, the harmonic distortion is of 0.00164% (THD+N). The signal to noise ratio is around 118dB. These are some reasons why the Orpheus Preamplifier is a marvelous device.
In keeping with Orpheus’s subtle styling, the basic silver chassis and natural brushed aluminum front panel lend a sense of timeless, understated elegance to any contemporary home interior. Their modest dimensions make it easy for the proud owner to choose uncompromising High End performance and uncompromising style.
In combination with a DVD player with onboard DTS, Dolby Digital, DVD-Audio and SACD decoding, the Orpheus Preamplifier offers a High End solution for surround enthusiasts, without compromising the high standards of pure two-channel audio.
The preamplifier Heritage is the newest product of Orpheus. Indeed, the topology is always dual mono meaning that the power supply of the right and left side are completely separated. Moreover, the electronics has been revised so that the PSU can provide more power to the output while minimizing the temperature drift. The left, right and digital grounds are connected only in a single point. The power supply is physically separated from the rest of the audio system to reduce the disturbances induced by transformers and diodes used to rectify the alternative current. The total power supplied by the transformers reach 350 [VA]. The windings for digital and analog voltages are completely separated. Each side has a capacitance reservoir greater than 55[mF] to properly rectify the voltage and limit its ripple noise. A ground connector is present on the rear of the PSU to connect all grounds together if necessary.
The new PSU allows to provide simultaneously enough power for the converter and preamp of the same Heritage line. This unit also integrates an infra-red receiver for RC control and a 4.3” TFT-LCD color screen to show all significant data. The control of the audio units is digitally made inside the power supply unit avoiding all interactions between analogue and digital electronics inside the audio unit. Three gilded strips per board transmit efficiently the power over the entire surface of the electronic board. Low power supplies have been provided for each part of the audio signal path to locally regulate voltages. The audio path has been optimized for better dynamic specifications.
The PSU Heritage is composed by one stylish treated aluminum box. The front panel is composed of the IR receiver, a standby LED, the LCD screen and the illuminated logo. The command buttons are place on the right side of the device. When the unit is turned on, a beautiful backlight illuminates the logo and indicates to the user that the device is ready to operate. Heatsinks have been cleverly integrated inside the device to optimize heat dissipation assuring perfect operating conditions. Its outstanding specifications, imposing size followed by refined and stylish curves makes this anodized aluminum piece of art remarkably stand apart from conventional preamplifier.
