Key Features of the Cen.Grand 9i-938 Preamplifier
Proprietary Linear Equalization Technology – Ultra-Precise Sound Reproduction
At the heart of the 9i-938 lies Cen.Grand’s exclusive Linear Equalization Technology, a fully balanced signal path employed in both input and output stages. This advanced topology provides:
- Outstanding signal-to-noise ratio (SNR)
- Excellent common-mode noise rejection
- Exceptionally clean, distortion-free audio signal transmission
- Balanced, transparent, and highly dynamic sound
Whether used in reference stereo systems or professional monitoring setups, the 9i-938 ensures absolute fidelity and tonal accuracy.
Versatile Input and Output Connectivity
The 9i-938 preamplifier integrates seamlessly into any high-end or professional-grade system, offering flexible balanced and symmetrical input/output options:
- 2 pairs XLR balanced inputs – ideal for true differential signal sources
- 2 pairs RCA inputs – internally balanced for symmetrical operation
- 2 pairs XLR balanced outputs – professional-grade output to power amplifiers
These connections allow for minimal signal loss and maximum compatibility with high-end components.
Precision Volume Control with MUSES72320 and MUSES02
To maintain uncompromising signal integrity and detail, the volume control section employs:
- MUSES72320 precision volume control IC
- MUSES02 high-performance op-amps
This combination ensures:
- Superior channel balance for accurate stereo imaging
- Ultra-low noise floor for micro-detail retrieval
- Wide dynamic control range: -65 dB to +5 dB
The result is a smooth, high-resolution listening experience suitable for critical listening and studio-grade performance.
Dual Operation Modes - Enhanced System Integration
The Cen.Grand 9i-938 adapts to a wide range of configurations with two selectable operating modes:
- Direct Mode – activates both volume control and amplification stages for full signal strength and dynamic headroom
- Buffer Mode – disables the amplifier section, keeping only the volume control active; ideal for use with active loudspeakers or external power amplifiers
The front-panel “Buffer” button allows quick, intuitive switching between the two modes depending on your system setup.
