The AVR307 is THX Ultra certified.
There are seven channels of amplification, and each channel is rated at 150W into 8 ohms and 185W into 4 ohms.
1% metal film resistors are used in the entire active circuitry, and a Class A pre-driver circuitry drives a Class AB MOSFET output stage.
With regards to analog A/V connections, there are 7 inputs and 5 outputs, all with stereo audio, composite video and S-Video capability, plus a set of 7.1 surround outputs.
A set of 5.1 inputs is present for the DVD-Audio/SACD buffs.
Note that these are analog pass-through inputs, and there are no bass management features that can be used with these inputs.
The AVR307 is not alone here: most receivers lack this capability.
There are also 2 component video inputs and 1 output.
The manual states that these should pass HDTV signals without compromise.
Their bandwidth specification, however, is stated to be 10 MHz.
This restricted bandwidth will definitely compromise the signal. Perhaps there is a mistake in the manual.
It should be more like 100 MHz.
On the digital side, there are 6 coaxial inputs and 5 optical inputs.
One output of each type is also available.
The digital inputs cannot be assigned to any source, however, the source name is editable in the setup menu.
An IEEE 1394 port is present as well, although this is not currently used.
There is no AC-3 RF demodulator and no phono section.
B&K makes external devices that can be purchased separately.
But what formats can it decode? Well, almost all! Dolby Digital 5.1 and EX, Dolby Pro Logic and DTS 5.1 are the supported formats.
Notable exceptions are Dolby Pro Logic II and DTS ES Matrix/Discrete.
Also, the THX certification brings with it the standard set of THX goodies like Cinema Re-Eq, Timbre Matching, Adaptive Decorrelation, and Bass Management.
All the decoding as well as the 96 kHz, 24 bit A/D and D/A conversion is performed using Motorola’s DigitalDNA technology with their 56362 chip.
