Exceptional Vacuum Tube Design
At its core, the C2800 features meticulously engineered vacuum tube circuitry, utilizing three 12AX7A and one 12AT7 tubes. This design minimizes noise and distortion, delivering a rich and immersive listening experience that captures the essence of your favorite recordings.
Comprehensive Input Options
Equipped with a total of 16 inputs, the C2800 offers extensive connectivity for all your audio sources. This includes seven analog inputs (three balanced, four unbalanced), two configurable phono inputs for both Moving Coil and Moving Magnet cartridges, and seven digital inputs housed within the DA2 Digital Audio Module. This versatility ensures seamless integration with both vintage and contemporary audio equipment.
Advanced Digital Audio Module
The DA2 Digital Audio Module is powered by a high-performance Quad Balanced, 8-channel, 32-bit Digital-to-Analog Converter (DAC). It supports high-resolution audio formats, including DSD512 and DXD 384kHz via USB, and features an HDMI Audio Return Channel (ARC) input for enhancing TV audio. This module is also upgradeable, ensuring future compatibility with emerging digital technologies.
Flexible Output Configurations
The C2800 provides three sets of variable balanced and unbalanced outputs, allowing for versatile system configurations such as bi-amping or connecting to multiple amplifiers. Output 1 includes trim level control for volume balancing, while Output 2 can be configured for mono or stereo, making it suitable for subwoofer integration or multi-room setups.
Reintroduction of Processor Loop
This model marks the return of the Processor Loop, enabling the seamless incorporation of external signal processors, equalizers, or room correction systems without disrupting the connection between the preamplifier and power amplifier. This feature offers enhanced flexibility for tailoring your audio system to your specific preferences.
Network Connectivity and App Control
With network connectivity, the C2800 can be controlled via the McIntosh Connect app, available for both Android and iOS devices. The app allows for convenient operation of key functions, including volume control and input selection, and facilitates firmware updates to keep your system current with the latest enhancements.
