Goldmund Telos 352 and 353 Power Amplifiers




















Goldmund is proud to present two new Telos Power Amplifiers: the Telos 352 (2 channels) and 353 (3 channels). They have been designed to support the Proteus 2-channel technology developed by Goldmund but can also be used as regular stereo or 3-channel amplifiers.
For those who are not familiar with Proteus, here is a short summary (white papers are available on request for science versed readers):
Proteus is a mathematical modeling technique created by the Goldmund fundamental research team led by Dr. Veronique Adam. It computes acoustic corrections that have the unique particularity of perfectly aligning the frequency response, the phase response and the time response of a speaker. This level of perfection has never been achieved before in any other existing Audio system. The corrections are included in a configuration file that is loaded inside the preamplifier and each driver is then amplified separately.
Although the performance of Proteus systems is nearly perfect, their disadvantage is the multiplication of the power amplifiers needed to drive the speakers and thus the cost.
The Telos 352 and 353 solve this cost problem by multiplying the number of amplification channels in one single amplifier case and with one single shared power supply. This makes them the ideal amplifiers for high end audio systems and for Media Room applications. These new amplifiers, like the Telos 350, can be mixed in complex configurations with the already existing Telos 2500, Telos 1000 or Telos 600 because they share the same group delay and the same sensitivity, also providing a substantial economy on large Proteus systems such as the Full Goldmund Epilogue.
If the Telos 352 has the exact same size and design as the Telos 350, the 353 is slightly higher, allowing the insertion of the board for the additional channel.
Telos 352 and 353 features:
Full-aluminum Mechanical Grounding Asymmetrical Construction: Visually surprising, the asymmetrical effect of having the heat sink on the right side and the weight concentrated on the front right foot proved remarkably efficient and allowed the size and weight of the amplifier to be seriously reduced without quality loss. This design also makes it easily stackable.
Internal Circuit: Using the same type of capacitors as the Telos 5000, a revised input circuit and no less than an Alize 6 D/A circuit, the only sacrifice on the Telos 352 and 353 is the suppression of the analog level control. Its approximate 3dB steps are rendered unnecessary by the easy adjustment to the half dB inside a Goldmund universal preamplifier.
Safety Features: To improve the peace of mind of clients who use several Telos 352/3, their protection circuitry is the most advanced of the Telos technology, just like in the Telos 350; it makes them perfectly safe in case of short-circuit and many other typical electrical incidents.
Optional DSP: Last, but not least, the Telos 352 and 353 provide an internal connection for an optional pluggable DSP board, just like the U-Telos amplifiers of the Goldmund Media Room. Connectable to a laptop by an USB connector, the future DSP board will allow Amplitude, Phase and Delay to be adjusted to set the Telos 352/3 in any configuration, including a complete Media Room environment.
