Meridian's G65 is perfect for any high performance 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. 

Meridian are the masters of Digital Signal Processing (DSP), a technology they adopted over 25 years ago and have been perfecting ever since. In short, DSP enables Meridian to achieve an extremely accurate reproduction of audio signals without loss in quality. 

One of the most exciting capabilities of DSP is the level of control and adaptability it offers. Here are just a few of the many revolutionary Meridian product features that would be simply impossible to reproduce in the conventional analogue domain...

Meridian Room Correction (MRC)

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.

Meridian SpeakerLink

Traditional audio systems often require screened, expensive cables to maintain their performance. Meridian's SpeakerLink uses a data cable that delivers pristine digital sound and control from one connection between Meridian components. The result is simple, unobtrusive, and cost-effective solutions that are easy to install.

FIFO Buffering

Sounds like jargon, and is a technology that lies deep within the operations of a digital audio system. But FIFO buffering is powerful and effective. 

Each sample of a digital recording must remain evenly spaced in time. But timing can vary, especially when reading discs. This is called “jitter”, and the effect is degrading to the sense of space and realism of an audio recording. 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.

Smart Source

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.

Meridian Apodising Filter

Another feature that sounds like jargon, but filters are critical in digital audio. Commonly they introduce distortion and harshness. Early digital recordings suffer from harshness due to primitive filters. After painstaking research, Meridian developed a special filter that avoids distortion and harshness, so it can be steeper, cleaning up the effects of early filters. The result: a better, cleaner sound from recordings old and new.

Upsampling

Using a complex digital filter to double the rate of samples from the source, the G65 can improve resolution of the finer details in the recording. This means that even with a standard source such as CD, the G65 can enhance the listening experience.

MHR (Meridian High Resolution)

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 digital audio content.

Partner the Meridian G65 with the Meridian UHD722 HDMI processor for the complete AV processor solution. Add either a Meridian G55 power amplifier and passive speakers of your choice, or Meridian DSP loudspeakers for the complete multi-channel audio solution.
