Standout Features:• 16 inputs: 7 analog, 2 phono, 7 digital• Dedicated Subwoofer output• Controllable by McIntosh Connect app• Includes Processor Loop and 8-band analog equalizer• Supports 24-bit/192kHz and DSD512 files• Roon Tested General: The C55 Preamplifier is a pinnacle of sonic excellence designed for audiophiles, music enthusiasts, and dedicated McIntosh fans alike. As a torchbearer of innovation, it takes the baton from its predecessor, the multi award-winning C53, and propels your home audio experience into new realms of audio nirvana. With precision and craftsmanship, the C55 proudly takes its place as a true industry leader. INPUTS IN ABUNDANCE With a staggering 16 inputs (9 analog and 7 digital), the C55 becomes the nerve center of your audio universe. Analog inputs include 3 balanced and 4 unbalanced connections, along with 2 phono inputs configurable for either Moving Coil or Moving Magnet phono cartridges to connect your turntable(s). Both phono inputs feature adjustable Gain in 6dB steps from 40dB to 64dB as well as RIAA equalization. The digital section is housed in our DA2 Digital Audio Module and is powered by an audiophile-grade Quad Balanced, 8-channel, 32-bit Digital-to-Analog Converter (DAC). The DA2 offers an array of connections, including an audio-only HDMI Audio Return Channel (ARC)1 input, ushering your TV sound into a new era through your home stereo system. Dolby® and DTS® multi-channel audio formats are expertly converted to exquisite two-channel audio for a captivating listening experience. The DA2's other 6 digital inputs consist of 2 coaxial, 2 optical, 1 USB, and 1 MCT. The USB input supports DSD512 and DXD 384kHz. The coax and optical inputs decode digital music up to 24-bit/192kHz for high resolution audio playback. And to get the best sound quality from the high definition audio on your SACD collection, the MCT input offers a secure, custom DSD connection when paired with our MCT series of SACD/CD Transports. The entire DA2 module is upgradeable and could be replaced by a future module should new digital technologies become available. INNOVATIVE OUTPUTS FOR PERSONALIZED LISTENING To connect the C55 to your power amplifier(s), there are 3 stereo sets of variable balanced and unbalanced outputs that offer advanced connection flexibility. All 3 sets of outputs can be active at the same time, and each can send the audio signal of the source component to 3 separate audio systems. The Main output and Output 1 have adjustable filtering capabilities for bi-amping, while Output 2 can be used to connect a subwoofer. Additionally, the Main output and Output 1 can be used for bi-amping a single speaker system via the built-in adjustable High Pass and Low Pass filters. In this setup, the High Pass outputs could be connected to a vacuum tube amplifier, and the Low Pass outputs could be connected to a solid-state amplifier. The adjustable crossover allows you to optimize the performance of your amplifiers to your speaker’s specifications and to your listening preferences. Output 1 offers trim level control, which allows two different amplifiers to be volume balanced when bi-amping. Furthermore, Output 2 can be configured as either mono or stereo and can send audio signal to a stereo audio system in another room, to a single mono subwoofer, or to 2 separate stereo subwoofers.2 The Processor Loop has unbalanced Send and Return connections. RETURN OF THE PROCESSOR LOOP The C55 features the return of the Processor Loop, something not available on the last few generations of McIntosh preamplifiers. The Processor Loop allows you to insert an external signal processor (such as our MQ112 Environmental Equalizer or MEN220 Room Correction System), dynamic range expanders, or other devices without having to place it between the preamplifier and power amplifier(s). This is usually more convenient and can allow for better performance. The Processor Loop is also the perfect place to connect an analog tape recorder, a high-end cassette deck, or a 3-head reel deck that allows you to record from a source component and hear the recording just seconds later so you can monitor your recordings. NETWORK CONNECTED FOR CONTROL AND UPDATES In addition to using the included remote control or the front panel controls, the C55 can be connected to your network which will unlock control options offered through our complementary Connect app (scheduled to be available April 2024). Designed for both Android and Apple devices, the Connect app can be used to control key functions of the C55 including Volume control as well as Input and Output selection. Select McIntosh source components3 that have a data cable connected to the C55 will be partially controllable via the app's Source Control feature. With Source Control, users will be able to control many of the source unit's functions from the app, such as changing radio stations on a tuner, or playing a disc in a CD Player. This feature will bring added convenience to setups that have a secondary set of power amplifiers and speakers connected to one of the C55's outputs, such as an outdoor system where you will no longer be forced to go inside to control its basic functionality. Another benefit of adding the C55 to your network is the ability to receive periodic firmware updates. These firmware releases can add new features or provide important performance updates. ADDITIONAL PERFORMANCE FEATURES 8-band analog equalizer to fine-tune your music with precision, creating a personalized audio experience (the equalizer can be bypassed if desired). High Drive Headphone Amplifier with Headphone Crossfeed Director (HXD®) technology brings an added dimension to headphone listening. Home Theater PassThru for seamless integration into your home theater system. Has received Roon Tested designation from Roon Labs. Power Control lets you easily turn other connected McIntosh components on and off. Data Ports can send remote control commands to connected source components. Electromagnetic Input Switching for reliable, noiseless, and distortion-free switching. Level Trim Adjustment for matching analog input levels to prevent abrupt changes in volume levels. Precision balanced, digitally controlled attenuator system for accurate volume control with 0.1dB accuracy. Fully regulated power supplies and a special R-core power transformer for stable, noise-free operation. Eco-friendly Power Management System that will turn the unit off after 30 minutes of inactivity (can be disabled). The 8-band analog equalizer offers precise adjustments at key audio frequencies.
