CHUBAN T11PRO Reference Berlin Voice 909 Fully Symmetrical Line Mono Hi-end Fully Balanced Amplifier Power 500W 8 Ohms

Evolution of T11PRO
In 2015, Transsion launched the balanced input, fully bridged amplifier T11, which is still on sale
In 2020, T11PRO was launched. It has a flagship large chassis, large transformer, large output power, and greater control
Line features
Derived from the 270,000-yuan Burmester 909 fully symmetrical X-Amp ultra-fast power amplifier circuit
Fully DC coupled circuit, with high damping characteristics, can drive all low-sensitivity large speakers
Fully true balanced input This machine only has xls balanced input
Fully bridged circuit
Adopting mono design
It has the rigorous sound of the German Burmester: high resolution, first-class control, and low frequency is unique
Design materials
Ultra-large and heavy chassis, 340*415*240 ultra-large size 15mm front panel, the rest 5mm aluminum plate The heat dissipation performance of the whole machine is first-class

Quality Assurance
To ensure quality, Transsion conducts comprehensive AP testing on every complete machine to ensure that the design indicators are met
Tests include: bandwidth, noise (signal-to-noise ratio), dynamic range, distortion, intermodulation distortion, channel separation, amplification factor, etc.
The whole machine is tested for 72 hours, the amplifier is tested for 1 hour at full load of 8 ohms, and the listening test is for more than 1 hou

The huge exposed radiator of the all-aluminum chassis The top plate, bottom plate, back plate and side plates of the all-aluminum heavy chassis are all 5mm thick aluminum plates
