About the 9008A
The MBL 9008 A is a powerful Reference Line power amplifier designed as a differential-balanced mono block amplifier, also usable as a stereo amplifier in single-ended mode. It combines Class A and Class AB amplification with Direct Push-Pull technology for high-precision signal processing and unparalleled resolution of musical nuances. It features switchable mains transformers for sound tuning and speaker impedance matching, two separate power input sockets, and a fully symmetrical signal flow for extremely quiet signal ground. The amplifier houses sixteen output devices delivering 840 watts of musical power at 4 Ω and a maximum pulse power of 2,200 watts at 2 Ω. Its power transistors are mounted on vibration-impeding solid copper, and it compensates transistor non-linearities via a unique Isolated Gain Cell circuit. The unit weighs 60 kg (132 lbs) and includes six high-quality solid copper connecting terminals with bi-wiring options.
