How to connect two analog mixing consoles together

Buy the EBTech cable tester on my Amazon store: http://astore.amazon.com/glbpro-20/detail/B0002GLCE0 Over the past year I have received multiple requests to do a video showing how to connect two mixers together, either for the purposes of supplementing the channel count on an existing mixer or for sending audio between two different venues or locations. Here it is!

How to connect a power amplifier to passive loudspeakers

In this video I discuss how to match and connect a power amplifier to passive loudspeakers in the context of live sound reinforcement. Although active speakers are all the rage these days there is nothing wrong with good old passive speakers, and they have the advantage of only needing a single connection, as opposed to the signal and power connections needed on an active cabinet. Bookmarks for video: 01:08 The difference between active and passive loudspeakers. 02:45 Overview of a typical modern power amplifier. 10:25 Overview of a typical passive loudspeaker connector panel. 11:08 Step 1: Ensure amplifier and loudspeakers are correctly matched. 11:35 Step 1A: Determine power handling capacity of your loudspeakers 12:52 Step 1B: Determine loudspeaker impedance. 13:32 Step 1C: Calculate power delivery of amplifier into loudspeaker, based on impedance. 14:37 How to calculate the combined impedance of multiple loudspeaker cabinets. 17:17 Step 2: Connect mixer to power amplifier 17:47 Power amplifier modes: stereo, parallel, bridge mono. 20:51 Daisy-chaining power amplifiers 22:25 Step 3: Connect amplifier to loudspeakers. 25:58 Setting amplifier gain and level controls.

Subwoofer Setup & Optimization - MartinLogan

A good subwoofer should disappear into the room, integrating with your music and movies instead of sticking out and being overly powerful. With this video you'll learn how to place a sub in your room and adjust the settings to blend seamlessly into your system for a better listening experience. We also discuss the different hookup methods you can use to connect your subwoofer to a receiver or processor.

Understanding Speaker Impedance and Speaker Switches

This video explains how speaker impedance matters, especially when connecting multiple speakers to your HiFi amp. It also demonstrates how speaker selector switches protect your amp from low impedance. For more details on this and more articles on connecting multiple speakers, please see my website: http://geoffthegreygeek.com/category/home-av/connecting-speakers/ Questions are generally answered from the webpage only.

Need more bottom end in your system? Sick of wimpy kick drums and feeble bass guitar? An active sub could be the solution you've been looking for!
