McIntosh C55 Preamplifier

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

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 complimentary 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.
