Power Amplifier 9008 A

The listening experience it creates when powering the scorching vocals of Janis Joplin can be soul-searing, yet nothing is hot to the touch with the MBL 9008 A. Thanks to its über-efficient heat sinks, this powerful amplifier runs barely warm, even when driving low impedance loudspeakers. Its first 50 watts of output are in pure Class A operation. With up to 840 watts of musical power at 4 ohms, and a maximum of 40 amps peak current in optimized balanced mono operation, the modest operating temperature for an amplifier of this size is a result of an abundance of heat-sink surface area…and MBL’s design commitment to creating a thermal buffer.

The 9008 A at a glance

  • Designed as a differential-balanced mono block amplifier, but can also be used as a stereo power amplifier in single-ended mode

  • Combination of Class A and Class AB amplification

  • Direct, high-precision signal processing by Direct Push-Pull technology

  • Unparalleled resolution of the finest musical nuances

  • Sound tuning/speaker impedance matching via two separate switchable power transformers

  • Two separate power input sockets

  • Extremely quiet signal ground by means of fully symmetrical signal flow from the input to the output

  • Power transistors located on a foundation of vibration-impeding solid copper

  • Compensation of all transistor non-linearities by means of unique Isolated Gain Cell circuit

  • Sixteen output devices deliver 840 watts of musical power (at 4 Ω) with an output current of 40 amps, maximum pulse power: 2,200 watts (at 2 Ω)

  • Six high-quality, in-house manufactured solid copper connecting terminals with the option of bi-wiring

  • Weight of 60 kg (136 lbs)
