Cheap 2 Channel Video Mixer
Update: This popular Cheap mixer is now available to buy for around $500, from BH Photo order today as they tend to go very quickly.
As you know TV equipment is not cheap, and you do need a large sum of money for broadcasting hardware, so here is a budget video mixer that would be ideal for a new startup church video department wanting to produce service DVDs for congregation members.
At around $500, it has reasonable features, and while not suitable for broadcast TV purposes, it will act as a spring board for training members of your video media department in live TV switching or video directing, and fufill the goal of simple mixing facilities for recording a church's service on DVD. In fact our church used this mixer for over 4 years to reliably record our services and produce a weekly video podcast before upgrading to a HD production studio.
The CMX07 is a 2 channel video mixer aimed at the consumer market, but can accept upto 4 camera inputs (2 SVideo and 2 Composite), but can only switch between 2 sources at a time.
The CMX7 (sold under Sima brand in the US) mixer was the first that we used at our church, and after some searching on the internet was chosen out of a short list of 2 products, the Edirol V4 VJ mixer and the CMX-07 video mixer. The main reason for choosing it was its simple interface and that for my video/TV ministry training application I needed to be able to simultaneously preview all my input sources, and the Edirol did not provide this.
The CMX-07 while having a Audio Mixer built in, you should not be using this, as all audio should be supplied from the churches Audio mixing desk (I presume any church starting a video department will already have a working sound unit).
In addition to this church video mixer, you will need a number of TV monitors corresponding to the number of cameras you will be using (probably 2 for a new department), plus an additional large one for monitoring the mixer video output being sent to your DVD recorder.
Video Mixer Design and Layout
The CMX07 has a cheap look, a plastic case and delicate controls, the unit however is very light and compact, which means that it can easily be carried and setup if you don't have a permanent place of worship.
Included with the mixer is the Power Adaptor, a S-Video cable and a stereo phono cable.
Setup and Operation of this church mixer
Setting up the CMX07 video mixer is quite easy, and just involves connecting the various Video sources to the mixer, connecting the preview outputs to the respective monitors and mixed Video output to the DVD recording device and large TV program monitor. The manual is simple, but explains all the required steps and anyone with some technical knowledge should be able to complete this.
Once everything is connected and you switch on the CMX07 church video mixer, it will go to its default settings. Even though the mixer has 4 video sources, you can only switch 2 at a time, so you need to configure both A and B buses with the required sources for switching. It should be noted that the mixer does not save any settings, so you need to configure the sources each time you switch the unit on. Switching between your 2 cameras is done by moving the "T" bar to either A or B bus and simply pressing the Video 1 or Video 2 button as required, and only requires a little bit of practise.
A few basic video transitions (dissolve, wipe and PIP) are provided, and using the "T" bar on A bus, select Video 1, choose the transition, on B bus select Video 2, move the "T" bar from bus A to B and you have your transition. An auto take button is also provided with adjustable speed if you prefer doing it that way.
If you have no previous TV or Video production experience, it is advisable to get someone in to training the church video department in basic switching operations and camera handling, as just pressing buttons will not give good looking visuals on the recorded DVDs.
