Revox presents the new Revox B77 MK III and at the same time its new, own Revox Analog Master Tapes Collection. Both manufactured in the Revox KLANGWERK in Villingen for perfect interplay.

ORIGINAL REVOX MOTORS
IMPROVED ORIGINAL REVOX TAPE HEADS
The B77 MK III is equipped with a three-motor drive
with direct drive and servo control. Two winding motors bring the tape reels up to operating speed in a
very short time or slow them down quickly, precisely
and sensitively. The winding motors are particularly
strong and robust. The technology of the controlled
capstan tone motor, which is sophisticated down to
the last detail, compensates for even barely perceptible fluctuations in speed. Revox relies on the engine
design that has been tried and tested for decades.
All Revox tape heads are professionally designed
and developed in-house and they are manufactured to the highest quality using our own processes.
Revox tape machines each have a tape head for
playback, recording and one erase head. The precision of the tape heads is crucial for the recording
and playback quality. The new Revox B77 MK III uses
improved original tape heads with a special alloy for
a significantly extended service life. Everything to
ensure the highest longevity and sound quality.
CONNECTIONS
The connection concept is suitable for both recording studio connections and private home systems:
XLR IN/OUT
Cinch / RCA via enclosed adapter
Switch for studio and home systems
Special feature XLR connector: Known from studio
and stage technology, XLR (External Live Return)
connections are characterized in particular by their
robustness, reliability and loss- and interferencefree signal transmission. The balanced XLR connection ensures the best sound and high-quality transmission – in professional recording studios as well
as in private audio systems. The Revox B77 MK III is
therefore ideally equipped for perfect recording and

MR89 AM/FM Tuner
Includes many advancements and new features to make radio listening more pleasurable
60dB output meters show the signal level that’s being delivered from the analog outputs
Exclusive radio-frequency circuitry
Advanced low distortion performance
Digital and analog outputs

While there is no doubting the popularity and permanence of paid music streaming services, there is still plenty of free music being broadcast over the air from thousands of traditional radio stations. And McIntosh has a long and distinguished history with radio and tuners. The McIntosh MR78 from the 1970s is considered by many to be one of the best – if not the best – tuners ever made. The MR89 AM/FM Tuner carries on with this tradition of tuner excellence by letting you enjoy the abundance of free music streaming over invisible airwaves.

The MR89 features exclusive McIntosh radio frequency (RF) circuitry that is capable of receiving both strong FM signals from nearby stations – something that can overload and cause distortion in lesser tuners – while also being able to tune in weaker FM signals located further away with little to no noise. The MR89’s advanced signal quality monitor can display detailed signal, multipath, and noise levels of the incoming RF signals to help fine tune optimal placement of your AM or FM antenna. It comes with our RAA2 AM antenna that features a 20-foot (6m) long cable that provides flexibility in placing the antenna for the best possible radio signal reception; your McIntosh dealer will be able to assist you in choosing the correct FM antenna based on your home’s location relative to your favorite FM stations. A pair of balanced and unbalanced analog outputs along with one each of digital coax and optical outputs are included to connect the MR89 to your home audio system.

McIntosh MR89 AM/FM Tuner
A multitude of advancements have been made in the MR89 to make your radio listening more pleasurable. Sensitivity, Signal to Noise Ratio, Harmonic Distortion, Channel Selectivity, and Stereo Separation were thoroughly analyzed and thoughtfully updated resulting in substantial performance improvements for each. A variety of new features have also been added. To help with lower quality FM stereo broadcasts, Stereo Blending has been upgraded with the introduction of a new High Blend option which blends the high frequency portion of the audio frequency range more aggressively. The new Softmute feature reduces audio output when receiving low quality stations or between-station static and noise. Another added method to reduce noise and enhance your listening experience is the new Highcut function that reduces high frequency audio content. Several aggressiveness settings are available for Stereo Blending, High Blend, Softmute, and Highcut to suit station quality and your listening preferences.

C2800 2-Channel Vacuum Tube Preamplifier 16 inputs: 7 analog, 2 phono, 7 digital 4 Vacuum Tubes: (3) 12AX7A and (1) 12AT7 Dedicated Subwoofer output Controllable by McIntosh Connect app Includes Processor Loop Supports 24-bit/192kHz and DSD512 files

The C2800 Vacuum Tube Preamplifier is a masterpiece of audio passion and engineering precision. Crafted for discerning audiophiles and music enthusiasts alike, performance has been woven into the very fabric of this audio treasure. The C2800 has proudly earned the McIntosh name.

At the heart of the C2800 lies methodically designed vacuum tube circuitry. Leveraging the latest designs to all but eliminate noise and distortion, the C2800 reduces them to minuscule levels. Its four vacuum tubes, or valves, deliver a listening experience that transcends expectations.

INPUTS IN ABUNDANCE
With its 9 analog and 7 digital inputs (16 total inputs), the C2800 will become the nucleus of your home audio system. There are 3 balanced and 4 unbalanced analog inputs, plus 2 phono inputs that can be configured 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.

Our DA2 Digital Audio Module houses the 7 digital inputs and is powered by an audiophile-grade Quad Balanced, 8-channel, 32-bit Digital-to-Analog Converter (DAC). The DA2 offers a variety of inputs, including an audio-only HDMI Audio Return Channel (ARC)1 input that will give your TV sound new life when played through your home stereo system. Multi-channel audio formats from Dolby® and DTS® will be expertly converted to two-channel audio for an enthralling listening experience.

The DA2 has 6 other digital inputs: 2 coaxial, 2 optical, 1 USB, and 1 MCT. The coax and optical inputs decode digital music up to 24-bit/192kHz for high resolution audio playback, while the USB input supports DSD512 and DXD 384kHz. 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
Offering advanced connection flexibility, there are 3 stereo sets of variable balanced and unbalanced outputs to connect the C2800 to your power amplifier(s). All sets of outputs can be active simultaneously, and each can send the audio signal from the source component to 3 separate audio systems.

Bi-amping a single speaker system can be accomplished using the Main output and Output 1 and their built-in adjustable High Pass and Low Pass filters. In this configuration, 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. Then the adjustable crossover would let you 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.

Additionally, Output 2 can be configured as either mono or stereo to allow it to send audio signal to a stereo audio system in another room, to a single mono subwoofer, or to 2 separate stereo subwoofers.2

McIntosh Preamplifier back panel
The Processor Loop has unbalanced Send and Return connections.
RETURN OF THE PROCESSOR LOOP

The C2800 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 C2800 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 C2800 including Volume control as well as Input and Output selection. control circuitry bypass setting for each input.
