AudioQuest Carbon 48 4K/8K/10K HDMI Cable at Vinyl Sound Toronto Canada

The AudioQuest Carbon 48 is a 48Gbps HDMI 2.1 cable from AudioQuest (Irvine, California, USA), available at Vinyl Sound in Toronto, Canada. Built for the demands of next-generation home theatre, the Carbon 48 delivers 48Gbps bandwidth supporting 8K/60, 4K/120, and professional 10K Ultra HD video with Dynamic HDR and eARC, using Solid 5% Silver-Plated Long-Grain Copper conductors on all A/V and eARC signal pairs. AudioQuest's Level-3 Noise Dissipation, the most advanced noise-control architecture in the AudioQuest 48G HDMI lineup, applies a carbon layer sandwiched between metal layers around the four FRL and eARC pairs, with directional noise control extended to all 19 HDMI conductors.

48Gbps Bandwidth and 8K/10K/4K/120 Video Performance

The AudioQuest Carbon 48 carries the full 48Gbps bandwidth specified by HDMI 2.1, enabling 8K video at 60 frames per second, 4K at 120 frames per second, and professional 10K Ultra HD resolution. Dynamic HDR formats including HDR10+, Dolby Vision, and HLG are fully supported, as is Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) for gaming applications. The Carbon 48 also carries eARC for lossless audio return from compatible displays, with dedicated eARC conductors built from the same 5% Silver-Plated Long-Grain Copper used for the primary A/V signal pairs. This bandwidth headroom ensures the Carbon 48 remains capable across current and near-future display and source device combinations.

Level-3 Noise Dissipation and 5% Silver-Plated Conductors

AudioQuest's Level-3 Noise Dissipation is the highest noise-control specification in the AudioQuest HDMI 48G range, and the defining technical feature of the Carbon 48. Around the four Fixed Rate Link (FRL) pairs and the eARC pair, AudioQuest applies a carbon layer sandwiched between two metal layers, creating a high-loss noise trap that absorbs and dissipates RF energy at the most signal-critical conductors before it can reach the ground reference. This carbon-layer architecture goes beyond the metal-only shields used in Level-1 and Level-2 AudioQuest HDMI cables, targeting the RF frequencies most likely to degrade high-bandwidth video and lossless audio transmission. All 19 HDMI conductors, including A/V signal pairs, eARC, all ground-reference drains, and control and power conductors, are additionally treated with directional noise-dissipation control, preventing noise on secondary conductors from coupling into primary signal paths. The 1.25% silver ground-reference conductor further stabilizes the reference plane throughout the cable.

Key Features

Frequently Asked Questions

What is the AudioQuest Carbon 48 HDMI cable?

The AudioQuest Carbon 48 is a 48Gbps HDMI 2.1 cable built with Solid 5% Silver-Plated Long-Grain Copper conductors, a 1.25% silver ground reference, and Level-3 Noise Dissipation featuring a carbon layer sandwiched between metal layers around all FRL and eARC signal pairs. It supports 10K, 8K/60, and 4K/120 video with Dynamic HDR and eARC, and applies directional noise control to all 19 HDMI conductors. It is AudioQuest's highest noise-dissipation 48G HDMI cable and is available at Vinyl Sound in Toronto, Canada.

How does the AudioQuest Carbon 48 compare to the AudioQuest Blueberry or Forest 48 HDMI cables?

The AudioQuest Carbon 48 sits above the Blueberry and Forest 48 in the AudioQuest HDMI lineup. The Blueberry is an 18Gbps HDMI 2.0 cable with Level-1 Noise Dissipation and Solid Long-Grain Copper conductors, suited to 4K/60 HDR systems. The Forest 48 steps into the 48Gbps HDMI 2.1 tier with Level-1 Noise Dissipation but uses a simpler conductor and shield configuration. The Carbon 48 advances to 5% Silver-Plated LGC conductors, a 1.25% silver ground reference, and Level-3 Noise Dissipation with the carbon-layer sandwich around the critical FRL and eARC pairs, making it the appropriate choice for 8K, 4K/120, and high-performance home theatre and gaming systems where signal integrity at 48Gbps is non-negotiable.

What is Level-3 Noise Dissipation and how does it differ from Level-1?

AudioQuest's Level-3 Noise Dissipation adds a high-loss carbon layer between two metal shielding layers around the four Fixed Rate Link pairs and the eARC pair, the conductors carrying the highest-bandwidth and most noise-sensitive signals in an HDMI 2.1 cable. Level-1 Noise Dissipation, used on cables such as the Blueberry, applies directional noise control to all 19 conductors but uses metal shielding only, without the carbon absorption layer. The carbon layer in Level-3 targets RF frequencies at which metal layers alone are less effective, providing an additional stage of noise absorption before energy reaches the ground-reference conductors. Both levels apply directional control to all 19 conductors, but Level-3 adds meaningfully greater protection at the most critical signal pairs.

Does the AudioQuest Carbon 48 support 4K/120 for gaming?

Yes, the AudioQuest Carbon 48 fully supports 4K at 120 frames per second, which is the native output resolution and refresh rate of the PlayStation 5 and Xbox Series X for compatible games and displays. It also supports Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM), both HDMI 2.1 features used by current gaming consoles and PC graphics cards to reduce input lag and screen tearing. The 48Gbps bandwidth of the Carbon 48 provides the headroom required for 4K/120 with HDR simultaneously, which is the most demanding signal combination current gaming hardware produces.

What is eARC and how does the AudioQuest Carbon 48 support it?

eARC, or enhanced Audio Return Channel, is an HDMI 2.1 feature that allows a television to send high-bandwidth, lossless audio back to a connected AV receiver or soundbar over the same HDMI cable used for video. Unlike the original ARC, which was restricted to compressed audio, eARC supports Dolby TrueHD, DTS-HD Master Audio, and object-based formats such as Dolby Atmos and DTS:X at full lossless quality. The AudioQuest Carbon 48 dedicates a pair of Solid 5% Silver-Plated Long-Grain Copper conductors to the eARC signal and includes those conductors in its Level-3 Noise Dissipation treatment, ensuring the audio return path benefits from the same noise control as the primary video signal.

Where can I buy the AudioQuest Carbon 48 HDMI cable in Toronto or Canada?

The AudioQuest Carbon 48 HDMI cable is available at Vinyl Sound, an authorized AudioQuest dealer in Toronto, Canada. Vinyl Sound carries the full AudioQuest HDMI 48G lineup in-store and online, with complete manufacturer warranty support for Canadian customers.

Is the AudioQuest Carbon 48 compatible with HDMI 2.0 devices?

Yes, the AudioQuest Carbon 48 is fully backward compatible with HDMI 2.0 and HDMI 1.4 devices. HDMI cables are passive and the bandwidth they support represents a ceiling, not a requirement, so the Carbon 48 will work correctly with any device that has a standard HDMI output or input regardless of the HDMI version that device supports. The cable's superior conductor and noise-dissipation design also benefits lower-bandwidth signals, providing cleaner transmission even when the full 48Gbps capability is not in use.
