Equipped with the Audyssey Platinum suite of DSP algorithms, the V7705 features Audyssey MultEQ XT32 automatic room correction. With the included microphone, MultEQ XT32 is designed to analyze each speaker's (and subwoofer's) output at up to eight measurement locations and generate digital filters to help optimize each channel for the correct frequency and time domain response.

Audyssey Dynamic Volume smooths out disruptive volume jumps, such as with loud commercials, letting you listen at lower levels while still enjoying clear dialogue, music, and sound effects, while Audyssey Dynamic EQ provides full-range clarity at virtually any listening level. Audyssey Low Frequency Containment uses psychoacoustic algorithms to deliver a full-range balance, including deep bass, without disturbing close-by neighbors or those in others rooms, and features a multi-step adjustment.

Audyssey Sub EQ HT provides individual DSP tailoring of each subwoofer in a dual-subwoofer setup, allowing deeper bass with enhanced definition when compared to a single-subwoofer configuration. Additionally, the Audyssey MultEQ Editor app lets you view and adjust settings for detailed tuning and customize the sound more precisely to your room and tastes.

The AV7705 features multiple HDAM modules, which are engineered to provide a fast slew rate, wideband performance, and enhanced dynamic range for optimum sound quality. Current Feedback technology, rather than the typical voltage feedback configuration, helps provide a wide, closed-loop bandwidth and steep slew rate to further augment fidelity with wideband audio sources.

The HDAM is designed to outperform op-amp solutions with its higher speed, helping to keep the audio signal clean and tuned for enhanced sound performance.

Well suited for custom installs and remote troubleshooting, the AV7705 has a variety of features to provide enhanced control and compatibility with third-party and custom integration solutions, including IP control via either wired LAN or Wi-Fi. For compatibility with other components, use the remote control input and output on the rear panel, along with the flasher input and 12V trigger output. For direct connection to external home automation and control equipment, the RS-232C serial port provides remote monitoring. The AV7705 also features Crestron Connected for integration with home automation equipment.

The AV7705 offers extended support for integration into custom installs, including support for "ihiji Invision" remote system management technology, "Domotz Pro" remote monitoring and management technology, as well as a web interface to control and set up the pre-amp from a computer on the same network.

The AV7705 features two subwoofer outputs to help smooth out low frequencies and enhance bass dispersion, mitigating peaks and audible dips.

The AV7705 can be controlled with your smart TV remote through the HDMI CEC functionality associated with your Smart TV. Simply set "HDMI Control" to "on" in the AV7705, then set "Smart Menu" to "on" and begin controlling the pre-amp with your TV remote. The Smart Menu home screen provides you quick access to source and surround mode selections, the pre-amp's setup menu, and four Smart Select options.

Four Smart Select buttons store your preferred setup for each source, including input, volume, and Audyssey configuration.

Once you connect your display to the AV7705 via HDMI, the Marantz Setup Assistant appears on the screen to guide you through the setup, helping you establish settings to help achieve the best sound quality for your configuration.
