You'll have read about the new Onkyo TX-SR606 multichannel receiver below, so here are details of the two new budget models in the range, the £300 TX-SR576 and £250 TX-SR506 (pictured), which replaces the Award-winning TX-SR505.

Both models include 7.1-channel surround processing for Dolby Digital EX, Dolby Pro-Logic IIx, DTS-ES, DTS 96/24 and DTS Neo:6.

As for video connectivity, the TX-SR576 has three 1080p-compatible HDMI 1.2 inputs, as well as additional onboard decoding for Dolby Digital Plus audio.

You'll also find three 1080p-compatible HDMI inputs on the TX-SR506, but it uses pass-through connections, so you'll need to connect an additional optical or coaxial cable to hear multichannel audio from your Sky box or DVD/Blu-ray player.

Each model has Onkyo's dual-source powered zone 2 capability, which allows the receiver's surround amplifier channels to power stereo speakers in a second room while still listening to 5.1-channel sound in the main zone.

Setting up the receivers should be simple too. The Audyssey 2EQ automatic calibration system uses a supplied microphone to analyse the system's acoustic output and correctly calibrate the output for the speakers and environment.

The TX-SR576 and TX-SR506 will be available in silver and black. Full technical specifications are as follows:
