Cen.Grand 9i-938 Pre Amp

The 9i-938 Pre Amp was designed in 2016 to drive large loudspeakers. It has played an important role in all of our exhibits at many hifi shows over the years. It can drive even the most inefficient speakers from any manufacturer with power to spare.

Features

9i-938 Pre-Amp consists of discrete components and uses an all balanced circuit topology called "Linear equalization" in which both the inputs and output are fully balanced.

9i-938 has two XLR, two RCA input and two sets of XLR outputs. The volume control uses a combination of MUSES72320 + MUSES02 with a range of -65db to +5db.

The 9i-938 can be operated in direct mode, with both volume and amplifier circuits working. It can also be operated in buffer mode, where only the volume part works and the amplifier part does not. Which mode is the best depends on the choice of the user.

The 9i-938 Pre Amp has two modes. The left is the standard mode (Direct) and the right is volume mode (Buffer). In volume mode the pre-amp circuit is disabled. Just press the Buffer button to switch between these two modes.
