G65 Surround Controller
Perfect for any high performance theatre

Forming the heart of a powerful and flexible Meridian home theatre system, G65 is a highly flexible Surround Controller, featuring many of Meridian’s key technologies such as Meridian Room Correction (MRC) while combining high performance, connectivity and ease of use.

When partnered with the HD621, the G65 features a comprehensive input capability to accommodate the widest range of audio and video sources. Equipped with SpeakerLink and balanced analogue outputs, the G65 is equally at home in Meridian Digital Theatres and with analogue loudspeaker-based systems.

 

Key Features

A 7.1 Surround Controller with class leading audio fidelity - Meridian Room Correction for perfect sound in any room.

A Linear Power Supply ensures superb performance on both analogue and digital systems. 

Multiple outputs which enable the creation of both passive and DSP based systems from the same Surround Controller.

Re-clocking of the digital audio signal removes timing errors for superior clarity and resolution.

With its extensive Research and Development programme Meridian has pioneered the development of a host of innovative audio technologies many of which feature in today’s Meridian products.

Room shape, size, furnishing and loudspeaker positions all influence the sound of any system. The result is often uneven sound - low frequencies are too loud in some places and too quiet in others. Meridian's Room Correction system uses powerful DSP to smooth out uneven room resonances for clearer sound and better imaging.

Traditional audio systems often require large, expensive cables to maintain their performance. Meridian's SpeakerLink uses an “Ethernet style” cable that delivers pristine digital sound and control down a single cable between Meridian components. The result is simple, unobtrusive, and cost-effective cables that are easy to install

Each sample of a digital recording must remain evenly spaced in time. Unfortunately, timing can vary, especially when reading discs. This is “jitter”, degrading music's sense of space and diminishing realism. Meridian's multiple “First In, First Out” buffering system minimises jitter, ensuring perfect timing and improved clarity. You enjoy a clearer feeling of the instruments and their interrelationship.

Music, movies and other sources each need their own settings to play correctly. Usually you have to select the right settings yourself. A Meridian system, however, analyses the incoming content and automatically selects the correct group of settings – we call them presets – for the source. You just sit back and enjoy the experience.

Filters are critical in digital audio. Commonly they introduce distortion and harshness because of "pre-ringing". Early digital recordings suffer from harshness too, due to primitive filters. After painstaking research, Meridian developed a special filter that avoids pre-ringing, so it can be steeper, cleaning up the effects of early filters. The result: a better, cleaner sound from recordings old and new.

Uses a complex digital filter to double the rate of samples from the source to improve resolution of the finer details in the record. This means that even with a standard source such as CD using our upsampling technology we are able to significantly enhance the listening experience.

A patented Meridian audio format that combines high bandwidth, security and low jitter. MHR gets the highest possible sound quality in playback systems that use Meridian and enables the encoded transmission of PCM, MQA and DSD.
