AudioQuest Cherry Cola 48 Active Optical HDMI is AudioQuest’s premier solution for long-length HDMI applications that demand full 48Gbps/8K bandwidth without an external power source.Available in 5m, 10m, and 15m lengths, Cherry Cola 48 is the premier solution for long-length HDMI applications. Regardless of current need for 4K/120 or 8K/60, Cherry Cola 48 offers superior performance for 10.2Gbps, 18Gbps, and 48Gbps sources, still without requiring an external power source.For longer lengths (20m, 25m, 30m), Cherry Cola 18 continues to provide superior low-noise performance. Cherry Cola 18 set the standard that Cherry Cola 48 continues with AudioQuest’s Level-4+ Noise-Dissipation:Galvanic-Isolation provides RF-immunity for the A/V signals, Silver-Plated Ground-Reference, all metal controlled for direction (including control and power conductors), and Global-Carbon Mesh-Network Noise-Dissipation.While eARC is not commonly used in video projector setups, AudioQuest follows an extremist always-prepared mandate.
