Belkin has unveiled a pair of innovative new iPod products, which it is exhibiting at Macworld Expo and CES.

The company announced TuneStudio — an innovative four-channel audio mixer for iPods — and it also revealed its new Bluetooth Dock Adaptor.

TuneStudio works with fifth generation iPods (with video). It's a portable four-channel mixer that lets users create and record audio at high-quality directly to their music player. The company sees it as useful for podcasters and also for bands who just want to record a jam or live session.

Each channel is equipped with 3-band EQ, pan and level controls. Audio is recorded at 16-bit, 44kHz quality. Additional features include: Phantom-power-enabled XLR inputs which provide up to 60 dB of microphone gain, and a high-quality stereo compressor which enhances audio dynamics and keeps audio levels within the recording limits of the iPod.

TuneStudio also acts as an external USB sound card, allowing the input of audio from a PC source as well as output to a PC from any of TuneStudio’s connector inputs. LEDs indicate master audio level, power status, peak indication, compressor activity, and recording status. The device is set to launch this summer and will cost $179.

The company's new Bluetooth Dock adaptor lets users roam with their iPod playlists and control their music wirelessly through the stereo dock. It's a two-part system, consisting of the adaptor (which attaches to the stereo or other sound output device) and the iPod adaptor which slots into the player's Dock connector.

In use the solution lets you use your iPod as a remote control at ranges up to 30-feet. You can expect good quality audio over the Bluetooth connection. The device is scheduled to ship in March, when it will cost $129.
