Design of the Integra DTR-80.3 A/V Receiver
The Integra DTR-80.3 A/V receiver is a substantial component, weighing in at almost 53 pounds. The overall style is classic Integra, with a simple curved front panel made from brushed aluminum along with a very crisp white LED display. To the right of the display is a large volume knob in addition to a standard set of cursor buttons that allow for easy navigation of the DTR-80.3 setup menus as well as its multi-media interface. To the left of the display is the power button along with discrete power buttons for zones two through four. Directly under the display is a small series of buttons which provide access to tuner functionality as well as tone controls and toggles for the various listening modes. Just below those buttons is a complete set of input buttons which allow for easy control of the receiver. In the lower-right corner of the DTR-80.3 is the auxiliary input which provides an external HDMI connection along with analog and optical-digital audio inputs and a composite video input. Just to the left of the auxiliary input is a USB jack which can also be used for your favorite Apple iDevice. The headphone jack is on the lower-left corner along with the microphone jack for Audyssey.
The rear panel of the DTR-80.3 offers support for a wide array of components and is color coded to help distinguish inputs from outputs. Inputs have a black background while outputs have a white or checkered background.
The DTR-80.3 receiver is THX Ultra2 Plus certified and supports eight HDMI 1.4a inputs and two HDMI 1.4a outputs which can be operated simultaneously or independently. This should be more than enough to handle the HDMI devices in a typical home theater with plenty of room for expansion. The receiver supports a full complement of analog audio and video inputs with three component video inputs, five composite video inputs, four S-Video inputs, one 7.1 multi-channel input, and nine sets of stereo analog RCA inputs. The DTR-80.3 supports seven digital audio inputs (3 coaxial and 4 optical). The DTR-80.3 includes a second USB input on the rear panel which can be used with a USB storage device or an optional UWF-1 Wi-Fi adapter. A very nice touch is the inclusion of a complete set of nine channel pre-outs along with two independent subwoofer pre-outs should you want to use the DTR-80.3 with external amplifiers. You will also find an Ethernet connector on the rear panel which allows the DTR-80.3 to access your home network and the internet.
The speaker jacks on the DTR-80.3 support a full complement of eleven speakers including front-height and front-wide channels. There are plenty of options available if you don't have a full set of eleven speakers in your theater. For example, if you don't use the front-height channels, you can use those channels to bi-amp your front speakers if your speakers support a bi-amp configuration. If you don't use the front-wide channels, you can use those channels to power zone two. Finally, you can configure the DTR-80.3 to use the surround-back and surround channels to power zone three and zone four speakers respectively. The optimal configuration is to use external amplifiers to power the multi-zones, but the configuration options are available to handle a variety of installation needs.
The remaining connections on the DTR-80.3 back panel allow for antenna connections for the AM/FM tuner. The DTR-80.3 includes a universal port for the connection of the optional UP-HT1 HD Radio module and/or the UP-A1 iPod dock. The UP-HT1 has a universal port connection so both optional modules can be connected to the DTR-80.3. The DTR-80.3 includes two IR inputs and one IR output jack as well as an RS-232 jack which can be used to control the DTR-80.3 with an external control system. Three 12 Volt DC Triggers are also included, which allows you to turn on another device, such as an external amplifier for multi-zone operations.
The DTR-80.3 comes with a very nice, backlit remote.
From a technology perspective, the DTR-80.3 introduces several new features into the Integra line-up. For room correction, the DTR-80.3 uses the latest Audyssey MultEQ XT32 technology. According to Audyssey, the MultEQ XT32 delivers 32 times the filter resolution of the MultEQ XT technology. Audyssey MultEQ XT32 provides more than ten thousand individual control points and applies its filter technology to all channels, including the subwoofers. As of the latest Integra firmware release on March 16, 2012, the DTR-80.3 supports Audyssey Pro which allows a professional calibrator the ability to measure up to 32 positions in the room and adjust the target sound curves using a graphical interface on a PC.
For those lucky enough to have a theater with front-height and front-wide speakers, the DTR-80.3 provides three different processing solutions to help you enjoy those extra channels. Dolby PLIIz processing can start with stereo or 5.1/7.1 channels and deliver a 7.2/9.2 channel mix using the front-height channels. Audyssey DSX processing starts with 5.1/7.1 channels or a DTS-ES mix and adds the front-wide channels first and then the front-height channels if they are present. DTS Neo:X processing starts with stereo, 5.1/7.1 channels or a DTS-ES mix and delivers up to a 9.2 channel mix using both the front-height and front-wide channels. In case you are wondering about the math on the number of channels, the rear-surround channels must be disabled when utilizing both the front-height and front-wide channels on the DTR-80.3.
On the video side of things, the DTR-80.3 utilizes the IDT HQV Vida VHD1900 video processor to upscale all video sources to 1080p via HDMI. The DTR-80.3 also includes a Marvel Qdeo 4K processor which allows for scaling to 4K resolution of 3840x2160 at 24/25/30 Hz. While most people will not have a 4K display in their theater for a while, the custom installer market will appreciate the inclusion of 4K support in the DTR-80.3 for their clients jumping into the 4K projector products.
