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.

From the behringer website:

Premium ultra-low noise, high headroom analog mixer
2 state-of-the-art xenyx mic preamps comparable to stand-alone boutique preamps
Neo-classic "british" 3-band eqs for warm and musical sound
1 post fader fx send per channel for external fx devices
1 stereo aux return for fx applications or as separate stereo input
Main mix outputs plus separate control room, phones and stereo cd/tape outputs
Cd/tape inputs assignable to main mix or control room/phones outputs
High-quality components and exceptionally rugged construction ensure long life.

The layout of the XDJ-RX2 has also changed in a way that brings it more in line with the Pro CDJ and XDJ units. The mixer section has also been rearranged to more accurately represent the layout of the DJM-900NX2 and other pro DJ mixers, and is very similar to the DJM-450. Any DJs using a pro Pioneer setup when playing out in the club and then using the XDJ-RX2 for practice at home won't have to think twice anymore when finding the features they want - everything will be second-nature.

Changes to the layout include:



Cue buttons are now placed above their respective channel and a master cue button has been added.
Master and booth levels are now at the top of the mixer section
The browse knob and buttons have been moved to the right-hand side of the touchscreen
The Browse/Tag List/Info/Menu buttons have been moved above the touchscreen


Hot new features you can expect from the XDJ-RX2 are:



A 7-inch full-colour touchscreen, in-line with the XDJ series

8 performance pads on each deck, in-line with the DDJ controller series - these can be used for tactile control of 8 Hot Cues, Beat Loop, Slip Loop and Beat Jump.

A parameter knob enabling you to control the sound colour effects

Track filter, short cut and QWERTY keyboard features can be used to search for tracks

Needle search via the touch screen

Beat FX controls have been added

There are now 2 MIC inputs

Yes, hd32a is a portable, powered speaker - but we like to think of it as more of a portable weapon! like other members of rcf's hd powered speakers (hd10a, hd12a), you can plug a microphone directly into the back of this one.

By using a pair of these as your front of house speakers, you'll be doing just fine. With 1400w peak power delivering 131 db max spl, the 2" titanium dome compression driver (with a 3" voice coil) is the not-so-secret ingredient to help get your vocals soaring where they need to.

Hd32a weighs in at 18.6 kg, and looks set to be a big part of the future for rcf powered speakers.
