Meridian Room Correction

The G68 includes Meridian Room Correction, accessed via the Meridian Configuration program. This unique feature automatically measures room resonances using a simple microphone, employing powerful DSP technology to build up to 60 high-quality digital filters that limit the reverberation time at resonant frequencies to a value similar to the overall reverberation time of the room. The filters can be examined graphically and numerically, and edited if required. Room correction can have a dramatic effect on the sound, removing muddiness and improving stereo and surround imaging.

Multi-zone capabilities

Multi-zone/recording features include two sets of S-video and composite video with conversion from S to composite (ADV, AXV, and XXV only) and stereo digital and analogue outputs providing independent sources to two additional zones. Meridian communications (DIN and BNC) are also included along with RS232 and USB serial ports for maintenance and control, infra-red sensor input, and up to three 12V triggers.

Integral tuner

The tuner provides AM (LW/MW) and FM (VHF stereo Band II) reception and is fitted with its own A/D stage. Digital signal processing provides a sophisticated FM stereo blend/width control which allows the user to minimise noise on a received signal. There is also a DSP-based low-pass filter and a whistle filter for improved AM reception.
