The MM7025 is an ideal two-channel power amplifier with whopping 140W RMS into 8 ohms per channel. Use it in an AV setup to give your front channels an earth-moving boost or in combination with a HiFi Pre-Amplifier to create a high quality 2 Channel System. Current Feedback Current Feedback amplification is a well known, Marantz original circuit technology. The Current Feedback amplifier technology fits perfectly with the high requirements set for Super Audio software providing wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited resulting in a very low phase shift. Marantz receivers and amplifiers equipped with Current Feedback can keep the phase compensation via Negative FeedBack (NFB) to a minimum, resulting in high through-rate, excellent transient response and superb sonic transparency for the full bandwidth. Unlike conventional Voltage Feedback amplification, the Current Feedback amplification makes the power amplifier in-sensitive to difficult loudspeaker loads. Customized Components On paper an electrical component might look excellent but the result may fall short of the combined design expectations. Marantz selects the appropriate components for the specific design application. In some cases its simply not possible to use standard components that meet the high Marantz standards. These components will then be specially made for Marantz in close cooperation with the Marantz engineers. DC-Trigger A DC trigger is an assignable voltage output which can automatically control for example an electrical projection screen, lowering it when the DVD input is chosen on the receiver. IR Flasher IN The IR-Flasher IN is a standardized connection to control the AV system by external IR receivers independent of the infra red control format used. On the IR-Flasher OUT an IR-Emitter can be connected to controlled third brand components. The third connection link to this is the IR-Receiver INPUT which is similar to the IR-Flasher In, but it outputs a voltage to directly feet an external IR-Receiver eye. Please check capability per product in the specification section. Linear drive power supply LDPS Marantz own technology to design a power supply capable to follow all details of an audio signal to reproduce the finest sound quality.

2-Channel Phono Preamplifier Moving Coil & Moving Magnet inputs Analog outputs + USB for ripping to computer The MP100 is the first dedicated phono preamplifier from McIntosh and is designed to help both new and experienced vinyl lovers get the most fidelity, performance and most importantly enjoyment from their albums. Like all McIntosh products, the MP100 is packed with features designed specifically for the vinyl lover including: Moving Coil and Moving Magnet inputs; Moving Coil and Moving Magnet adjustable loading (6 settings each); balanced and unbalanced analog outputs; optical, coax and USB digital outputs; and a Mono switch for when playing mono records to decrease noise and play the signal correctly. There are many ways to integrate the MP100 into your audio system. If youre new to vinyl and just building your system, it can become the main part of your setup. Or if you already have a system with an older preamp you dont want to part with, the MP100 is an excellent way to add modern phono features. If youve got a home theatersystem and would like to add a turntable, the MP100 is an easy way to add full phono preamp capabilities without having to get a full-sized stereo preamp that would undoubtedly duplicate many of your home theater processors features. While spinning vinyl on a turntable is a great and unique way to enjoy music, theres no denying the convenience of having digital versions of the albums. When used with a properly configured conversion program, the MP100 can rip the records to a computer via USB to produce high quality digital files. The digital outputs are fixed at 24-bit/96kHz to capture the full dynamic range of a record while optimizing digital file size. If an album has a very loud section, the clipping indicator will alert you so you can lower the digital output in order to produce a distortion-free recording. Compact in size at just 3 tall, it has many ageless McIntosh design cues. It shares the same 11.5 narrow chassis design as the MXA70 Integrated Audio System, MHA100 Headphone Amplifier and MB50 Streaming Audio Player to help build a cohesive system. It can also easily be added to a system comprised of standard, wider width chassis.
For music enthusiasts who wont accept compromise, the reference RC-1590 preamplifier is in a class by itself. The Rotel RC-1590 stereo preamplifier has been engineered to the highest audio performance levels and provides an incredible level of control and flexibility for the user. Starting with a high performance power supply consisting of two Rotel custom built toroidal transformers for maximum efficiency and low magnetic fields, these transformers provide low-noise isolation between the analog and digital signals. They are part of a reference-grade power supply consisting of individual analog and digital regulator circuits with custom-made slit-foil capacitors. Slit-foil capacitors have very quick charge/discharge times and low signal loss ensuring tight bass performance. Rotel engineers wanted to create a reference quality stereo preamplifier to match with our new RB-1590 stereo power amplifier. Every aspect of component selection and circuit topography was designed and carefully evaluated during multiple listening sessions to ensure the highest fidelity. For example, analog and digital circuits were designed separately, by specialized Rotel teams. Analog inputs are all very low noise circuitry and include a high performance moving magnet phono stage. Digital inputs are fully isolated and feature a precision 32bit 768KHz Digital to Analog Converter (DAC). The RC-1590 is fully feature-laden with Balanced XLR and Unbalanced RCA inputs and outputs, a TI precision volume control IC, a fixed volume line output, dual mono subwoofer outputs, digital outputs (Coax and Optical), digital inputs (3 Coax and 3 Optical), Aux, CD, and Tuner analog inputs, Internal APTX Bluetooth (supports APTX and standard Bluetooth) with rear mounted external antenna, a front USB iPod with 2.1A charging input, and rear panel PC-USB 24bit 192KHz input supporting DSD (Windows) and DoP (MAC computers DSD over PCM). Other essential features include a remote control, 2 x 12-volt trigger outputs, a dimmable display, an automatic power off function (configurable), RS232 and IP control for automation system integration, Internet based software updates, Rotel Link connection, a detachable IEC power cord, an external IR remote input, and a front mounted 3.5mm headphone output jack. For music enthusiasts who wonâ??t accept compromise, the RC-1590 preamplifier is in a class by itself, at a price that belies its incredible performance. 80 dB 110 dB >75 dB >75 dB 20Hz 20kHz, (±0.5 dB, Max) 90 dB SPDIF LPCM (up to 192kHz 24bit) USB Audio Class 1.0 (up to 96kHz 24bit) USB Audio Class 2.0 (up to 192kHz 24bit)* *Driver installation required DSD Replay native or DoP 120 V, 60 Hz 230 V, 50 Hz 25 watts.
