Features

Exclusive McIntosh Power Assurance System: The McIntosh MAC6700 employs a collection of technologies that enhance performance and reliability while protecting the stereo receiver and loudspeakers.

• Output Autoformers: McIntosh output Autoformers ensure every connected speaker receives full power regardless of its impedance. This unique patented McIntosh technology delivers the full-rated amplifier output with the least possible distortion into loudspeaker impedances of 2, 4, or 8Ω; you get all the power you paid for and the freedom to choose any loudspeaker. The Autoformers also provide perfect DC protection for your valuable loudspeakers.
• Power Guard Circuit: Power Guard is waveform comparison circuit continuously monitors both input and output signals. Power Guard dynamically adjusts the input level to avoid clipping while preventing harsh sounding distortion. The receiver's front-panel LED indicator will flash when Power Guard is activated.
• Sentry Monitor Technology: McIntosh Sentry Monitor power output stage protection circuits ensure the MAC6700 will have a long and trouble-free operating life. Sentry Monitor is a fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating level; resets automatically.
• ThermalTrak & Thermal Protection: The stereo receiver uses ThermalTrak output transistors for lower distortion and cool operation. Built-in thermal protection circuits guard against overheating. If the stereo receiver overheats due to improper ventilation and/or high ambient operating temperature, AC Power is removed from the MAC6700. Normal operation will resume when the operating temperature is in a safe range again.

Classic McIntosh Design: The MAC6700 stereo receiver incorporates classic McIntosh design cues, including a black glass front-panel, rotary knobs, illuminated logo, and brushed aluminum end-caps. The receiver's large power transformer, multiple filter capacitors with 120 Joules of energy storage and regulated power supply ensure stable noise free operation.

AM/FM Tuner: The built in AM/FM tuner receives your favorite radio stations with clarity that is free from noise and distortion. It features the same high performance as McIntosh's stand alone tuners, along with 20 presets for each radio band, as well as a remote AM antenna. An amplified AM antenna is included for excellent AM reception (no FM antenna is included).

Electromagnetic Input Switching: Electronic input switching is used in McIntosh MAC6700 stereo receiver to switch the variety of source components connected. Rather than the commonly-used mechanical switches that will deteriorate with wear, electromagnetic switches are high tech switching nodes that allow very long, trouble-free operation.

Analog Audio Inputs & Record Outputs: The McIntosh MAC6700 stereo receiver is fitted with balanced & unbalanced analog audio inputs, as well as two phono (MM/MC) inputs.

• Balanced & Unbalanced Inputs: The McIntosh MAC6700 receiver is equipped with one balanced stereo XLR input and four unbalanced stereo RCA inputs. Balanced connections guard against induced noise and allow long cable runs without compromising sound quality.
• MM/MC Phono Inputs: The McIntosh MAC6700 has two dedicated phono sections, one for Moving Coil (MC) Phono Cartridges and the other for Moving Magnet (MM) Cartridges. Both phono sections provide the lowest possible noise and distortion. The RIAA Correction Equalization Circuitry utilizes close tolerance resistors and capacitors for an extremely flat frequency response. The MAC6700 will breathe new life into your record collection and deliver the best possible sound from your turntable.
• Record Output: The receiver also offers two sets of stereo RCA record outputs for connecting a recording device.

32-Bit/192kHz DAC: The McIntosh MAC6700's digital engine will decode your digital music at up to 32-bits and 192kHz, delivering McIntosh analog sound quality. The MAC6700 offers optical, coaxial, & USB-B digital inputs.

• Asynchronous USB-B Input: The stereo receiver features a asynchronous USB-B input for playing back music files from your computer. Asynchronous technology allows the digital clock inside the MAC6700's DAC to control the flow of data coming from your computer. This method of communication leads to less jitter (timing errors) for the MAC6700 to deal with which results in clearer more defined sound. The receiver can decode and play back high res 2ch stereo PCM audio signal up to 32-bit/192kHz from your Windows PC or Mac computer. Your Windows PC or Mac computer must meet the following system requirements -
  • Windows 7 (SP1), Windows 8, Windows 8.1, Windows 10; a Windows PC will require the installation of McIntosh's USB Audio Window Driver (available on the McIntosh website)
  • Mac OS X 10.6.8 or later; a Mac computer does not require the installation of an additional USB audio driver
• Optical & Coaxial Digital Inputs: The McIntosh MAC6700 has one optical (toslink) digital input and one coaxial (RCA) digital input. These digital inputs will decode 2ch stereo PCM signals up to 24-bit/96kHz.

Binding Post Speaker Terminals: McIntosh Patented gold-plated, binding-post speaker terminals deliver high current output to a single pair of loudspeakers. They accept large diameter wire (up to 10AWG), banana plugs (single only), and spade lugs. The receiver's Left & Right speaker channels have separate Positive (+) binding-post terminals, labeled "2Ω"/ "4Ω" / "8Ω". Each Left & Right speaker channel has only one Negative (-) binding-post terminal that is shared between the positive terminals.

Headphone Amp: The MAC6700 incorporates a built-in headphone amp with a front-panel 1/4" headphone jack. The built-in headphone amplifier features increased gain and output power, and is optimized and designed to power virtually all types of headphones (20-600Ω) for an enjoyable personal listening experience. Speaker outputs may or may not be muted during headphone playback; your choice.

Pre-Out, Pass Through, & Bi-Amp Compatible: When the MAC6700 is part of a home theater or multichannel audio system, the Right and Left Front channels from an AV processor or surround decoder can pass through the stereo receiver and onto its associated power amplifier. The stereo receiver can also be used as a preamplifier, so you can use a separate amplifier to power your loudspeakers. In addition, together with an additional separate power amplifier (sold separately), the MAC6700 can be used to bi-amplify a loudspeaker system.

Front-Panel & Remote Control: On the front-panel of the stereo receiver are Input & Volume rotary knobs, Output 1 and Output 2 buttons, Tone bypass, Mute button, and Standby/On button. The McIntosh MAC6700 also includes an IR remote control for wireless operation of the receiver. In addition, the remote operates other McIntosh audio components. The IR remote offers the following button functions - Power On/Off, Input Selection, Volume Up/Down, Setup/Menu, Numeric Keypad, and Playback Control.

• Precision Volume Control: Volume levels are controlled by a precision balanced digitally controlled attenuator system with an optical encoder rotary control. This assures a 0.1dB tracking accuracy between channels. There are 225 individual 0.5dB volume level steps with no noise as the volume level is changed.
• Bass & Treble: The Bass & Treble controls provide up to 12dB of boost or cut. The MAC6700 remembers the Bass & Treble Setting for each input.
• Balance Left/Right: You are also able to balance the output level of the stereo receiver's left & right output channels.
• Source Level: Each audio source input can be matched in level, preventing abrupt changes in volume levels.

Fluorescent Display + Illuminated Power Meters: The stereo receiver's front-panel display indicates source selection, volume levels, tone adjustments, and setup functions. The Illuminated power output watt meters on the MAC6700 are peak responding, and indicate the power output of the stereo receiver.

Custom Integration: The McIntosh MAC6700 offers advanced connectivity and control features often required for custom home integration using premium control systems.

• Power Control Connectors: The MAC6700 has the ability to automatically switch power on or off to source components via the Power Control connections. The MAC6700's "Main, "Trigger 1/2", and "PASSTHRU" Output Jacks (3.5mm) send power on/off signals (+12 volt/0volt) when connected to other McIntosh source components. The Power Control outputs can be assigned to activate when a given input or output is selected.
• Data Ports: The MAC6700's six Data Out Ports (3.5mm) send remote control signals to McIntosh source components. These Data Port connections allow for the remote operation of basic functions using the MAC6700's Remote Control.
• IR Input: The 3.5mm IR input allows the connection of an external IR receiver. With an external sensor connected to the MAC6700, remote control operation of the system is possible from another room and/or when the MAC6700 is located in a cabinet with the doors closed. The signal from a connected external IR receiver will have priority over the signal from the receiver's front-panel IR sensor.
• RS-232C Port: The stereo receiver's RS-232C port requires a 3.5mm stereo minijack to a subminiature DB 9 connector cable (sold separately) to transmit and receive RS-232 commands.
