McIntosh D150 Stereo Digital Preamplifier

For Purchase Please Contact Us (908) 874-3799 

Digital Preamplifier: The McIntosh D150 is a solid-state digital preamplifier with 6 total digital inputs for connection of your digital audio source components. Electronic input switching on all inputs provides reliable, noiseless, distortion free switching. There are two different ways the D150 may be used in an audio system -  
•    as the main audio preamplifier connected directly to a Power Amplifier
•    as a digital-to-analog converter with input switching connecting to an analog preamp
Classic McIntosh Design: The D150 digital preamplifier incorporates classic McIntosh design cues, including a black glass front-panel, rotary knobs, illuminated logo, and brushed aluminum end-caps.
Specially-Designed Power Supply: Fully regulated Power Supplies and a special R-Core Power Transformer ensure stable noise free operation even though the power line varies.
32-bit/500kHz DAC: The McIntosh D150 utilizes an 8-channel, 32-bit/500kHz DAC with advanced Quad Balanced, digital-to-analog circuitry for precision, dynamic sound with little distortion. The D150 is capable of handling the finest commercial recordings, assuring the best sound from your digital music collection. 
Asynchronous USB-B Input: The McIntosh D150 features a asynchronous USB-B input for playing back music files from your computer. Asynchronous technology allows the digital clock inside the D150's DAC to control the flow of data coming from your computer. This method of communication leads to less jitter (timing errors) for the D150 to deal with which results in clearer more defined sound. The D150 can decode and play back high res PCM & high fidelity DSD files from your Windows PC or Mac computer via its USB-B input. The digital preamp's USB-B input will accept 2ch stereo PCM signals up to 32-bit/384kHz and supports DSD64, DSD128 and DSD256 along with DXD 352.8kHz and DXD 384kHz. 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 D150 Digital Preamplifier is fitted with two optical (toslink) digital inputs and two coaxial (RCA) digital inputs. The optical and coax digital inputs will decode 2ch stereo PCM music files at up to 24-bit/192kHz for high resolution audio playback. 
MCT Port: To enjoy the high definition audio found on SACDs (16/24-bit; 32-192kHz), you can connect the D150 to McIntosh's MCT450 SACD/CD Transport (958MCT450, sold separately) via the MCT input on back of the digital preamplifier to create a secure and custom DSD connection. 
Fixed/Variable Balanced & Unbalanced Outputs: Balanced and unbalanced connections are available for both variable and fixed volume audio outputs, providing flexibility in setting up and connecting your system. The McIntosh D150 is equipped with a fixed balanced stereo XLR output and fixed unbalanced stereo RCA output, as well as a variable balanced stereo XLR output and variable unbalanced stereo RCA output. The Balanced outputs allow the connection of long cable lengths without a loss in sound quality. You can use Balanced and Unbalanced Outputs simultaneously, connected to different power amplifiers. 
Headphone Amp: The D150 offers a front-panel 1/4" headphone jack for connecting a set of low-impedance (20-600?), dynamic headphones, so you can enjoy your music in private. You will need to press the "Mute" button to mute the loudspeakers when listening to headphones.
Gold-Plated Connectors: The Input and Output connectors contacts are gold-plated for superior corrosion resistance and high electrical conductivity.
Front-Panel & Remote Control: On the front-panel of the preamplifier are Input & Volume rotary knobs, Setup button, Mute button, and Standby/On button. The McIntosh D150 also includes an IR remote control for wireless operation of the preamplifier. 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. 
Fluorescent Display: The D150's front-panel, fluorescent display indicates the Source Selection, Volume Level, Sampling Frequency, and Setup Mode Selections. The display brightness is adjustable. 
Custom Integration: The McIntosh D150 offers advanced connectivity and control features often required for custom home integration.
•    IR Input: The 3.5mm IR input allows the connection of an external IR receiver. With an external sensor connected to the D150, remote control operation of the system is possible from another room and/or when the D150 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 preamp's front-panel IR sensor. 
•    Power Control: The D150 has the ability to automatically switch power on or off to and from source components via the Power Control In/Out connections (3.5mm).
•    Data Port: The D150's Data Out Port (3.5mm) sends remote control signals to a McIntosh source component. This Data Port connection allows for the remote operation of basic functions using the D150's remote control.
