– New Kind of Amplification for the Best of Both Worlds.
Audio Aero designed the TransTrac® system (Transistor – Tube Relay Amplification Concept) with the idea to have the sound of a full tube amplifier out of a tube/transistor configuration. This unique system is a pure Class A balanced triode amplification with an additional D-MOSFET booster to increase output power.
The preamp stage delivers a perfectly balanced signal to the very linear triode power tubes (E34L). Then, the booster performs a perfect copy of the signal from the output transformer and increases both transformer impedance and output power. Each booster is trimmed to obtain a perfect balance between the two channels.
Both output transformers and booster are connected to the speaker terminal. Output transformer nominal impedance is 6 ohms but it will accept speaker impedances from 4 to 8 ohms. Only a local feedback is used to lower output impedance. When overdriven, tubes clip before boosters to always keep a pure Class A sound. All the reality and soundstage of a tube amp is reproduced in a unique, small and cost effective equipment, available in integrated and power version.
