Pro Sound Equipment and AV Accessories

A mixed aisle: sort by what the item does

This aisle holds several kinds of product, so the title matters more than the category. Look for speakers and amplifiers that make or boost sound, cables and splitters that carry audio or video, and power products such as distribution strips. Power sources vary: corded AC at 110 V, built-in batteries, or none at all for passive items. Connection types vary just as much, from XLR and RCA to USB, Bluetooth and 3.5 mm, so read the connector list first.

Bandwidth, distance and voltage on the spec sheet

For HDMI, 18 Gbps is the bandwidth that carries 4K at 60 Hz, so a cable or splitter rated lower may drop to a lower resolution. Long runs need extenders: a Cat6 HDMI extender can reach tens of meters where a plain cable cannot. Thicker wire has a lower AWG number. For power strips, check the rated voltage, such as 120 V, the outlet count and the plug type, so the unit matches your supply.

Questions about Pro Sound Equipment and AV Accessories

What does 18 Gbps mean on an HDMI cable?

It is the bandwidth the cable is rated to carry, enough for 4K at 60 Hz with standard color. Lower ratings may only manage 4K at 30 Hz or 1080p. Check that the cable, source and display all support the same level.

How far can an HDMI signal travel?

A passive cable stays reliable for a few meters at 4K, and quality varies. For longer distances, use an extender over Cat6 cable, which can reach tens of meters, or an active or optical cable.

Can I use a power distribution strip for audio gear?

Yes, if the voltage and plug match your supply and the total load stays within the strip's rating. Add up the wattage of everything plugged in, and keep audio cables away from power cords to reduce hum.
