System Overview
WaveCAST provides true, professional audio quality over Wi-Fi , and features DSP audio processing. Setting up and configuring
the WaveCAST for the Wi-Fi network is straightforward and simple. Up to four WaveCAST systems can be connected to the same
Wi-Fi network to provide multiple listening channels, supporting 45 connections in unicast mode, or 1500+ in multicast mode with
a strong network configuration (see "Router and Network Equipment Selection" on page 7).
The WaveCAST audio processor oers multiple preset audio options. The high quality audio can be optimized for hearing
assistance, music can have high-fidelity playback, and voice can be set for maximum speech intelligibility. Custom presets can
also be created to meet specific performance needs.
The new WaveCAST app provides an easy-to-use, intuitive user interface and will be available in iOS or Android. The app allows
listeners to easily select their channel and volume level once their personal device is connected to the Wi-Fi network.

WaveCAST
Wi-Fi Network Required
The WaveCAST connects to the installation location's Wi-Fi Network. It does not provide a network on it's own. The Wi-Fi network
will need to be installed and established before the WaveCAST can be used.
You may connect the device to a computer via a hardwired connection to help troubleshoot any networking problems.
Router and Network Equipment Selection
The WaveCAST does not come with its own router or networking equipment. It is intended to be set up on an already existing
Wi-Fi network; however, upgrades to your network equipment may be necessary depending on the performance desired from the
WaveCAST. For instance, a higher-end, more powerful router will allow more users to connect to your audio stream than using a
cheaper, less powerful router.
The WaveCAST system will put a demand on the network. If the network cannot handle the demand, whether because it is being
used for other networking needs or because the networking hardware is not strong enough, the WaveCAST will be unable to
reach it's maximum audience.
When streaming to a small or medium sized audience, a basic networking configuration may suce. When streaming music using
multiple channels (such as having several WaveCAST units on your network), a powerful router and network configuration is more
likely to be required.

Ethernet and Dante RJ-45 Connection
If connecting to a network or directly to a PC, a CAT 5e cable must be used. In some cases, (like older PCs) a crossover cable may
need to be used.
Audio Source Connections
IMPORTANT: When a suitable audio source has been determined, you MUST configure the audio source in the menu of the
WaveCAST before plugging that source in.
The WaveCAST transmitter will accept the following audio sources:
1. Balanced/Unbalanced Microphone with 12 volt phantom power (DIN 45596) on a 3-pin (XLR) connector.
2. Balanced/Unbalanced microphone with or without phantom power on 1/4 inch (TRS) jack.
3. Balanced/Unbalanced Line on a 3-pin (XLR) connector without phantom power.
4. Dante on an RJ-45 jack (optional).

Multi–Channel Sources
By constructing a simple resistive mixer, stereo (or 3 channel) sources can be connected to the WaveCAST. Additional channels
can be accommodated by adding a resistor for each source.
Note: The Dante audio input will automatically mix the left and right channels.
Connecting Additional Sound Systems
The Analog Audio Line Output (RCA) jack can be used for monitoring, recording, or routing the WaveCAST's processed audio
into another sound system. For help connecting your sound system, contact Williams AV's TechBlue technical support team.
Otherwise, audio output is only available over the Wi-Fi network.
Avoiding Hum in the Audio (as a Result of a Ground Loop)
A hum created by a ground loop can often be eliminated by connecting a capacitor in series with the audio line shield to the
transmitter’s ground. This method also maintains good radio frequency shielding. Determining the eectiveness of this method for
your installation usually requires some experimentation.

Selecting an Audio source Appropriate for Hearing Impaired Listeners
The WaveCAST transmits audio with excellent fidelity. Therefore, the audio source signal should be of the highest audio quality
and not subject to a compressor, limiter, reverberation, or other signal processing equipment. While compressed audio is available
through the WaveCAST, excessive compression is not helpful to the hearing impaired and can contribute to excessive noise in the
audio.

9
WaveCAST
The WaveCAST audio source signal is usually connected to a mixer’s line output signal which is behind the mixer’s parametric
equalizers but ahead of any equalization used for house loudspeakers.
If audio delay is available for use in large auditoriums, it’s usually best to use it. Because radio signals travel faster than sound,
delaying the transmitted audio so that an average listener (in the middle of the listening area) hears the transmitted audio a few
milliseconds after audio from the main sound reinforcement system speaker is helpful. This will also help audience members who
lip read.
Controls and Features
Power Button
Latching push-button switch turns the transmitter on or o. The desktop power supply provides power to the unit at all times.
OLED Display
This shows current operation settings and is also used with the menu control buttons for configuring the WaveCAST. Each time the
power of the unit is turned on, the OLED Display shows a Williams AV start-up screen. After seven seconds, the default Main Info
Screen screen will be displayed. The WaveCAST is now fully operational.
(NOTE: If the transmitter's internal tests fail, the transmitter will attempt to auto-recover by rebooting itself.)
Audio Input Level Indicator
The bar graph indicator shows audio level in 3dB steps at the input of the audio level processing circuit. The indicator is peak
responding and is calibrated so that optimum level is reached when the 0dB LED lights up often and the +9dB only lights
occasionally. Use the Audio Level settings in the menu to set the audio levels.
Input Overload Indication
The OLED Display shows an overload warning screen each time the audio signal exceeds the capacity of the input circuit. Either the
source of the audio coming in to the WaveCAST needs to be adjusted to correct this or the Audio Input Gain needs to be adjusted.
Menu Controls
The menu system can be navigated via the buttons on the front panel of the device. See "Navigating the Menu" on page 10 for
more details.
Headphone Jack
A headset plugged into the headphone jack allows monitoring the WaveCAST audio output after it gets processed.
Main Info Screen and Screen Navigation
The Main Info Screen will show the following information: Device Description, Audio Source, Audio Preset, Audio Input Gain Setting. The
IP address will be displayed if the device is connected to the network.
Multiple Channels
Up to 4 WaveCAST systems can be used on the same Wi-Fi network for multi-channel operation. Multi-channel operation will work
better on more powerful networks and routers.

the left, right, above or below. Use the corresponding buttons on the front panel to navigate the menu.
Navigating the Menu
• While the transmitter is displaying the Main Info Screen, the Up ^ and Down v buttons adjust the Audio Input Gain.
• The Menu button is a Enter/Exit Menu function only. It does not select anything within the menu. It allows the user to quickly
return to the Main Info Screen from any place in the menu.
• While the transmitter is displaying the Menu on the screen:
• The Up ^ button navigates upward in the menu, changes a setting, or acts as a page up on info screens.
• The Down v button navigates downward in the menu, changes a setting, or acts as a page down on info screens.
• The Left < button backs out of the menu one step at a time.
• The Right > button navigates forward in the menu or selects a setting. When entering a Description, IP Address, or Subnet
Mask for the Transmitter, this button advances to the next character.
Screen Time Out
When in the menu system, once a setting is selected, no additional action is necessary. If no buttons are pressed, after 5 minutes
the OLED will return to the Main Info Screen, then after another 10 minutes show a screen saver, then go blank after an amount of
time set in the Screen Time-Out preference (see "Screen Time-Out" on page 12).
System Settings
Settings can be selected using the arrows on the front panel of the WaveCAST to navigate the OLED menu system or be set via
the web interface by using a computer. Not all settings are available in the front panel menu or through the web interface, and
using both may be necessary for your initial set up.
Audio Settings
The Audio Settings provide the ability to change the audio characteristics for dierent listening applications, choose the input
source, adjust the input level, set audio presets, and adjust the headphone volume.
Audio Source
The Audio Source menu is used to configure the WaveCAST for the audio source jack and type of source that will be used. The
audio source must be configured in the menu before plugging the source into the jack.
The Audio Source menu has four possible selections to choose from: Analog Line In, Mic, Phantom Mic +12V, 400 Hz Test Tone or
Dante (optional).
Audio Input Gain
The Audio Input Gain adjusts the incoming audio level into the WaveCAST. Changes to the input level will aect the level indicated
by the front panel LED’s when audio is present. Audio Input Gain is adjustable from 0 dB to -50 dB in 1 dB steps.
