Description: McIntosh MX121 Home Theater Pre/processor W/Dolby TrueHD, DTS-HD - Complete Kit McIntosh MX121 Home Theater Pre/processor W/Dolby TrueHD, DTS-HD - Complete Kit General: This listing is for a complete MX-121 set from McIntosh with an official McIntosh shipping carton, manual, remote, and the Audyssey DSX microphone + tripod to automatically setup the equalizer to your room and speakers. No more fiddling with individual bands, settings, etc., to get the best sound possible in your home theater. Perfect for an audiophile that finds two channel performance just as important and home theater performance. In great cosmetic condition, with slight signs of use. Display is bit dim but very visible. Working same as the day it left the factory. Some of the HDMI features and standards may be older, but best results are usually achieved from running your sources directly to your display from experience. We have several multi-channel amplifiers available, and of course you can pair this with higher-end stereo only amplifiers from McIntosh, Audio Research, Krell, etc to truly customize your home theater amplification per channels/front and rear soundstage. This MX121 was also updated to the very latest firmware version available. McIntosh Performance Features Include: • HDMI 1.4a with 3D Passthru Switching There are six HDMI 1.4a Inputs. HDMI Output 1 includes the new Digital Audio Return Channel (ARC) signal from the TV1, thus eliminating the need for an extra cable and simplifies operation. HDMI inputs are compatible with Deep Color, x.v.Color, Auto Lipsync and HDMI Component Control. • Analog Video/Audio Switching with Scaling Component Video Inputs and Composite Video Inputs (Analog Video Signals) are also converted to a Digital Video Signal with resolution up to 1080P at the HDMI Outputs. • Balanced Inputs and Outputs A pair of Balanced high level Inputs and an eight channel Balanced Output are provided, permitting long cable lengths without a loss in sound quality. • Moving Magnet Phono Input There is a Precision Phono Preamplifier for Moving Magnet Cartridges. • Built-in Dolby True HD and DTS-HD Master Decoders The MX121 also provides built-in decoding of the Dolby Pro Logic IIz, Dolby Pro Logic IIx, Dolby Digital EX, DTS Neo6 and DTS-ES Sound Tracks. • Audyssey DSX® Audyssey DSX is a scalable system that adds new speakers to improve surround impression. Audyssey DSX first adds Wide channels for the biggest impact on envelopment and then creates Height channels to reproduce the next most important acoustical and perceptual cues. Surround Envelopment Processing is uséd to enhance the blend between the front and surround channels.

The SkyFi Testing Process for Preamplifiers: We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR. When we first power on a preamplifier we connect its RCA output to a Sencore PA81 Power Analyzer which simulates real world loading conditions and gives us an oscilloscope interface. The first order of business is checking that the volume control works smoothly throughout its entire range with acceptable channel balance. This is accomplished by feeding a 1KHz sine wave into one of the preamp’s line level inputs while monitoring the preamp’s output on an oscilloscope. We then switch to a 1KHz square wave to test the tone controls, loudness function, and filters where applicable. During this step we are watching for equal alteration of the test signal by both channels. This also helps us identify dirty controls that will need treatment. Once the basic line stage functions are verified, we test each input individually. This is especially important for devices that use relays to select their sources. If the preamp is equipped with a phono stage we test that as well. We use an inverse RIAA filter which allows us to feed a reference test signal into the phono input with the proper RIAA equalization and level. A square wave or sine sweep is uséd to verify that the device’s phono stage is faithfully reproducing the RIAA curve. If the preamp under test has balanced inputs and/or outputs these are tested as well. We finish up our bench testing with a listening test with our bench amplifier and reference speakers. During this test we check for hum or hiss that may not have shown up in earlier testing. We also check that all of the tone controls and filters perform as expected. If the preamplifier has remote control functions these are also tested. Preamps with tube circuits or complicated power supply topologies are connected at our long term test rig for extended stress testing under real world conditions.
