A great introduction to "how to use a mixer for live music production", for novices, or to get tips, or as an educational aid for Media Colleges and Schools. 

Even though the last update was in Jun 29, 2014 but the information provided in most of the videos are still relevant for beginners or armature or even for the experience sound engineer. 

  

Handy dB Reference Chart

I have enclosed herewith one of the notes from the Seminar I did years ago in Sound Reinforcement System. I Thought this might be handy for those who wants to know how much power increase in relation to dB increase.

Simple Tools

At present day, most of us involve in audio reproduction will certainly encounters problem with managing the audio for reproduction or processing. For instant, one of the most common fault is to do with ground loops which caused buzz, hum or hissing. A simple thing like cable defect, mismatch audio input level, improper cable conversion form balanced to unbalance, improper audio splitter can more or less introduce undesirable audio i/o which can degrade the quality of the audio.   

An example of such tools are: Rolls BUZZ OFF HE18, Rolls Cable Detect CT1 PRO, Behringer ULTRA-DI20, behringer CT100, Henry Engineering PatchBox II, galaxy Pro JIB/S 4 Way Splitter.

Hence, the following simple solution can somehow improve the audio ( i.e. removes buzz, hum caused by ground loop, matches level, detect faulty cables, convert high level to low level and so on and so forth).  I will discussed each one of these tools later. So in the meantime, stay tune.

Newly installed Broadcast Conty

We have successfully completed the job of installing the above On-Air Studio on the 8 Jan 2014. This on-Air Studio is ready for use. Notice the mixer is embedded into the table and look more tidy without all the cables laying around/on the tabletop.

The conty is equipped with the latest professional broadcast equipment from branded name such as AKG, Allen & Heath, Warfadale, Behringer, HP workstation, Presonus, Dell workstation, Arrakis System ( Radio Assist Application ) and so on.

 Partially completed broadcast conty (refer below), just few days before Christmas ( on the 23 Dec 2013 ).

                             

As seen above, the student are trying out the soon to be completed broadcast equipment.

Files\Winamp…you can change the location
but not necessarily, it best to leave as it is.
Click “ Next” to proceed.

Constant Voltage Speaker System

Recently I was involved in setting up an audio distribution system (100V) and the hardest part is to choose the type of speakers that suit the client requirement such as wide dispersion speakers, horn type speakers, indoor and outdoor type, interior type wall mount speakers and so on and so forth. In the end I manage to figure it out and the result is shown below:

The total power of the speakers is 91Watt which is less than the PA Amplifier output power of 120Watt. The system should function as required and what important is the client satisfied.

Online Radio Connectivity using Behringer UCA222

I found that the easiest method to connect an analog audio mixer to PC is using an audio interface and in this case I am using the UCA222 from Behringer. The UCA 222 use two sets of unbalanced RCA namely Input RCA ( L&R) and Output RCA(L&R). Download the Behringer UCA222 manual for more info. Impedance mismatch is the most troublesome problem ( i.e. Hum, distorted, imbalanced audio level ..etc.) especially if you are using external devices such as CD player, IPod, Ipad and similar to generate audio into line in of Laptop or PC. Now this can be minimized if you use UCA222. Try it to believe.

How To Configure Shoutcast

Reference:  Extracted from www.shoutcast.com/‎

 What is SHOUTcast?

SHOUTcast is a free-of-charge internet DJ solution. It allows anybody on the internet to broadcast audio from their PC to listeners across the globe. SHOUTcast relies on MP3 or AAC technology to deliver audio in a live situation. If you prefer to broadcast from your pc to your listeners the information below will have you broadcasting in no time. You may also switch between live and auto dj if you plan to broadcast live shows from your studio.

SHOUTcast DSP Plug-In for Winamp 5.x

SHOUTcast DSP Available

We're pleased to announce the release of SHOUTcast DSP 1.9.0. This release includes support for streaming in AAC+. Note that the client will also need to support AAC+ (we recommend last version of Winamp).

SHOUTcast DSP 2.x.x for Winamp: Download ShoutCast DSP 2.x.x
This is currently available for Windows. UNIX/Linux/etc version coming soon.

Step 1

Once the download has completed, you will need to install the software. Verify that Winamp is not running, then double click on the installer that you downloaded and follow the on-screen instructions. When the installation process has completed, start Winamp and open your preferences. Click on "DSP/Effects" in the menu to the left, and highlight "Nullsoft SHOUTcast Source DSP v2.x.x [dsp_sc.dll]". When you have selected it, a new window should pop up. You may now close your preferences window.

Step 2

Once you have highlighted the proper row, a dialog box will pop up. This is the main SHOUTcast DSP window. Here, you can configure the server, encoder, and audio settings that you will broadcast with. You can stream more then one kbps rate by setting up more then one Output account. This is common with broadcasters who wish to broadcast a high bandwidth stream for pc listeners and a lower kbps rate (like 64 kbps aac+) for listeners on mobile devices.

Step 3

Select the "Output" tab at the top of your DSP window. Select "Output 1" under the selection box, and fill in all of the following fields properly.

Address:
Here, you need to enter the server that was given to you in the welcome email you received from ReliaStream. Your radio address will vary and it depends what server your station is set up on. be sure to look over your welcome email for all of your station details. Make sure that you put in the proper server, or else you will not be able to connect. See our example pictures.

Port:
In this field, you need to enter the port that was given to you in your welcome email. It should contain 4 numbers. Once again, this must be set properly or else you will be unable to connect.

Password:
Last, but not least, you need to set the password that was given to you in your welcome email, or the one that you changed it to. Enter this here, and make sure there are no mistakes.

Step 4
Yellowpage setup (streaming server display details) Click on the "Yellowpages" tab right above where you entered all of the previous information. If you'd like your server to be listed in the SHOUTcast directory, check the "Make this server public" box, and fill in all of the information below the box in a proper manner. If you do not have a web site you should at least enter your Stream Start Page. This is located in your radio account (under Quick Links).

Step 5
Encoder Settings (select streaming audio format) Select the "Encoder" tab at the top of your DSP window. Choose the Output # you wish to work with. If you only have one station then choose Output 1. The Encoder Type can be set to either MP3 or AAC+. In most cases it will set to MP3. If you plan to stream 64 kbps aac+ then select AAC+ as your encoder. The higher the kbps rate the better the sound quality. Only enter the kbps rate you purchased!! If you try to stream at a higher kbps rate your account will be suspended automatically. MP3 audio sounds very good and is compatible with just about every media player on the market. AAC+ is only compatible with Winamp and Windows Media Player (with a plugin), but sounds much better at lower qualities. Be sure to choose wisely. In the Encoder Settings dropdown, select the bitrate that you ordered from us, and be sure that the line you selected has "Stereo" at the end, so individual sounds will come out of both of your listeners speakers. 

Warning: If you stream at a bitrate higher than what you have ordered, your account may be deactivated or suspended by the shoutcast hosting service.

Step 6

Go back to the "Output" tab in your DSP window. Make sure "Output 1" is selected, and then click the connect button. In the status box above the button, if you are connected you should see an update in the Status section (time and then "Sent xxxx bytes"). You may have to start your radio software before connecting to get this to work properly. Make sure your radio server is ON and AUTO DJ is off or deactivated before trying to stream live. Most people having problems streaming live (99.9% of the time) have a setting wrong. Check all of your settings. If you are still having trouble connecting let us know and we will do our best to help you. Once you are connected you are ready to broadcast. Please view all of our help guides. There are many things to consider when streaming live and many things to watch out for. USA clients should choose one of our USA servers when broadcasting live. Overseas clients should choose our European server to broadcast to. Make sure you modem can handle the constant upload and make sure your modem provider allows constant uploading. If you have any questions be sure to ask our support team... Good luck and happy broadcasting!!
