The 3.5mm TRS Stereo Audio Cable is the standard aux cable for analog stereo audio. Connects headphones, speakers, car stereos, and any device with a 3.5mm jack. No digital processing — pure analog audio with zero latency. Cable quality matters for lengths over 3m — look for shielded cables with gold-plated plugs.
Cables
MIDI cables connect synthesizers, drum machines, and audio interface MIDI ports in a unidirectional chain — MIDI OUT to MIDI IN. Despite five pins, only three carry signal. MIDI is 31.25 kbps, so cable quality barely matters at typical lengths. Standard lengths are 1.5m, 3m, 5m, and 7.5m. Practical maximum is approximately 15m before signal degradation causes note dropouts. Shielded cables prevent RFI interference from power cables.
6.35mm TRS to 6.35mm TRS Balanced Audio Cable
This cable connects audio interface balanced TRS outputs to studio monitors with TRS inputs (KRK ROKIT, Yamaha HS5/HS7, Adam Audio). The 6.35mm TRS connector carries a balanced signal: tip (+), ring (-), sleeve (ground). Common lengths for studio use are 1m, 2m, and 3m. Ensure the cable is TRS (3-conductor), not TS (2-conductor instrument cable) — a TS cable will work but only carries unbalanced signal. Check by counting the black rings on the plug: 2 rings = TRS balanced, 1 ring = TS unbalanced.
Coaxial S/PDIF Digital Audio Cable (RCA)
Coaxial S/PDIF connects Blu-ray players (Panasonic DP-UB820, Sony UBP-X800M2), game consoles, and CD players to AV receivers and soundbars for PCM or 5.1/7.1 Dolby Digital / DTS surround. The cable looks identical to analog RCA but requires 75-ohm impedance. Standard RCA cables (25-50 ohms) often work at short distances but may cause jitter or dropouts on longer runs. Practical maximum is about 10m. Orange RCA connector by convention on some equipment, but not standardized.
The DisplayPort 1.4 Cable (HBR3) at 32.4Gbps is the mainstream cable for gaming monitors, handling 4K@120Hz with DSC or 8K@30Hz. Supports MST daisy-chaining for multi-monitor setups. Passive cables work up to 3m — for longer desk runs, use VESA-certified active cables (up to 15m, but they're directional: source→display).
DisplayPort 2.1 Cable (DP80 / UHBR 20)
The DisplayPort 2.1 Cable (DP80 / UHBR 20) delivers up to 80Gbps bandwidth for 4K@240Hz or 8K@60Hz with DSC. The newest and fastest DisplayPort cable for next-gen gaming monitors. Very short passive length (1m max) due to extreme signal speeds — active cables extend to 10m. Limited product availability as of 2025.
DisplayPort to HDMI Cable (Passive, DP++)
The DisplayPort to HDMI Cable (Passive, DP++) converts a DisplayPort output to HDMI using DP Dual-Mode (DP++) — a passive conversion that requires DP++ support on the source device. Limited to HDMI 1.4 spec: 4K@30Hz maximum, no HDR, no 4K@60Hz. For higher specs, use an active USB-C to HDMI or DP to HDMI adapter instead.
The DVI-D Dual Link Cable carries digital video at up to 7.92Gbps for 2560x1600@60Hz. The dual-link variant uses all available pins for maximum resolution. Found on older monitors and GPUs — no audio support, video only. Being replaced by DisplayPort and HDMI. Mark as legacy.
Ethernet Cable (Cat 6, Gigabit)
The Ethernet Cable (Cat 6, Gigabit) with RJ-45 connectors supports Gigabit (1Gbps) wired networking. Cat 6 cabling handles Gigabit at up to 100m and even 10G at up to 55m. Always faster and more stable than Wi-Fi for TVs, consoles, streaming devices, and desktops. Backward compatible with 100Mbps and 10Mbps networks.
HDMI High Speed Cable (10.2Gbps)
The HDMI High Speed Cable (10.2Gbps) at 10.2Gbps handles 4K@30Hz or 1080p@60Hz — the budget HDMI cable still found bundled with many devices. Fine for 1080p gaming, HD streaming, and older Blu-ray players. Won't do 4K@60Hz with HDR — for that, step up to Premium High Speed (18Gbps). Passive cables work up to 5m without issues.
HDMI Premium High Speed Cable (18Gbps)
The HDMI Premium High Speed Cable (18Gbps) handles 18Gbps bandwidth for 4K@60Hz video with HDR — the mainstream cable for most 4K setups. Connects Blu-ray players, streaming boxes, and older consoles to 4K TVs. Supports ARC for TV-to-soundbar audio. Passive runs up to 5m are reliable. No need to upgrade to Ultra High Speed unless you're pushing 4K@120Hz.
HDMI Ultra High Speed Cable (48Gbps)
The HDMI Ultra High Speed Cable (48Gbps) is the top-tier HDMI cable, rated at 48Gbps with FRL signaling for 8K@60Hz or 4K@120Hz video. This is the cable you need for PS5, Xbox Series X, and any 2021+ 4K TV to unlock full gaming performance with VRR, ALLM, and eARC. Passive cables run up to 3m — longer runs need active cables up to 15m. Look for the 'Ultra High Speed' certification hologram to avoid fakes.
IEC C13 Power Cord (Kettle Cord)
The standard 'kettle cord' or 'computer power cable.' One end plugs into the device's IEC C14 inlet; the other has a country-specific mains plug (EU Schuko, UK BS 1363, US NEMA 5-15). Rated 10A/250VAC internationally (15A/250VAC North America). AWG 18 is standard for most consumer use. Common lengths: 1m, 1.8m (6ft), 3m. For audiophile applications, shielded power cables exist but measurable audio quality differences are disputed by engineers.
The figure-8 cord (IEC C7/C8) is the compact alternative to the kettle cord, found on smaller electronics where grounded 3-pin is not required. Adam Audio T5V and T7V studio monitors use the C8 inlet, as do some slim Blu-ray players and older game console bricks. Rated 2.5A/250VAC. Available in polarized (tab on one side) and non-polarized variants. Unlike C13/C14 which is grounded, the C7/C8 is ungrounded (2 conductors only).
Micro HDMI to HDMI Cable (HDMI 2.0)
The Micro HDMI to HDMI Cable (HDMI 2.0) connects Raspberry Pi, GoPro cameras, and drones to standard HDMI displays. Carries 18Gbps bandwidth for 4K@60Hz video with full audio. The tiny Micro HDMI (Type D) end is fragile — avoid putting strain on the connector. Most are available in lengths from 0.3m to 3m.
Micro HDMI to HDMI Cable (HDMI 2.1, 4K@60Hz)
The Micro HDMI to HDMI cable in HDMI 2.1 specification is a frequent confusion source: the cable physically cannot carry full 48 Gbps due to the micro connector's contact design, but supports 18 Gbps (HDMI 2.0) — sufficient for 4K@60Hz HDR, the practical limit of all current Micro HDMI devices. Raspberry Pi 5 outputs 4K@60Hz per port regardless of cable. Maximum reliable passive length is 2m. The common mistake is buying HDMI 1.4 cables expecting 4K — any HDMI 2.0+ rated cable works.
Mini DisplayPort to DisplayPort 1.4 Cable
The Mini DisplayPort to DisplayPort 1.4 Cable connects Microsoft Surface, older MacBooks, and compact GPUs to standard DisplayPort monitors. Carries 32.4Gbps bandwidth for 8K@30Hz or 4K@120Hz with DSC. Passive cable — no electronics needed. Available in lengths up to 3m.
Mini DisplayPort to HDMI Cable (Passive, DP++)
The Mini DisplayPort to HDMI Cable (Passive, DP++) converts a DisplayPort output to HDMI using DP Dual-Mode (DP++) — a passive conversion that requires DP++ support on the source device. Limited to HDMI 1.4 spec: 4K@30Hz maximum, no HDR, no 4K@60Hz. For higher specs, use an active USB-C to HDMI or DP to HDMI adapter instead.
Mini HDMI to HDMI Cable (HDMI 2.0)
The Mini HDMI to HDMI Cable (HDMI 2.0) connects DSLR cameras, tablets, and camcorders with Mini HDMI (Type C) output to standard TVs and monitors. Carries 18Gbps bandwidth for 4K@60Hz video. Essential for photographers and videographers who need on-set monitoring. Available in lengths from 0.5m to 5m.
The Optical TOSLINK Audio Cable carries digital audio over fiber optic — immune to electrical interference. The most popular cable for connecting a TV to a soundbar. Supports compressed 5.1 surround (Dolby Digital/DTS) and 2-channel PCM stereo. Cannot carry lossless Dolby Atmos or DTS:X — for that, use HDMI eARC.
RCA Phono Cable with Ground Wire (Turntable Cable)
Standard RCA cables cannot substitute for a turntable phono cable in most setups because cartridges output extremely low-level signals (2-5mV for moving magnet) highly susceptible to interference. The separate ground wire connects turntable chassis to preamp chassis, eliminating hum. Turntable phono cables also have specific capacitance requirements (100-200 pF/m) — high-capacitance cables roll off high frequencies from MM cartridges. Most turntables (Audio-Technica AT-LP120XUSB, Rega Planar 1, Pro-Ject Debut) have a built-in cable. The Technics SL-1500C has a detachable cable for upgrades.
The RCA Stereo Audio Cable (Pair) carries two channels of analog audio — left (white) and right (red). A home theater staple since the 1970s for connecting turntables, CD players, receivers, and soundbars. Pure analog with zero processing delay. No surround sound — stereo only. For digital audio, use optical or HDMI.
The Thunderbolt 3 Cable (USB-C) at 40Gbps supports dual 4K@60Hz displays and 100W power delivery. Critical gotcha: passive cables only hit 40Gbps at 0.5m — longer passive cables drop to 20Gbps. For full speed at longer lengths, use active Thunderbolt 3 cables (up to 100m). Backward compatible with USB 3.2 and USB 2.0 devices.
The Thunderbolt 4 Cable (USB-C) delivers 40Gbps bandwidth with mandatory DP Alt Mode video, PCIe tunneling, and 100W USB Power Delivery. Intel-certified for dual 4K displays or a single 8K. Every TB4 cable is also a USB4 cable — fully backward compatible. Passive cables max out at 2m at full speed. Requires E-Marker chip.
