Functions

The CZA-1300 Amplifier is a fully integrated 70 Volt amplifier designed to integrate seamlessly with the EPIC platform and provide audio in large areas like Cafeterias, Gymnasiums, and Hallways. This is a network-connected amplifier which facilitates paging and emergency notifications as part of the EPIC platform. It is easy-to-use, easy-to-install, and has a simple user interface. When used in conjunction with an Uninterruptible Power Supply (UPS), during emergencies, paging can still be heard. This unit can be installed as part of the SAFE System (Signal Alert For Education)®. It can also be connected to an XD Receiver and used as an intercom for full duplex audio.

Process

1. Physically install components in the room such as Speakers and/or AV Touch Wall Control.
2. Confirm BLE (Bluetooth Low Energy) dongle is connected to USB port.
3. Verify Input power is selected correctly. In the US, set to 100V – 120V.
4. Turn the Amplifier on by pressing the power switch.
5. Start Epic, update the firmware, and continue the setup up using the EPIC software.

Configuring

1. Install the Device Configuration App (for Apple and Android Phones). Search for the Device Configuration App by Audio Enhancement. For more information on the Device Configuration please visit audioenhancement.com.
2. Start the Device Configuration App.
3. Select the BLE dongle for the CZA-1300 you are configuring. If Multiple BLE dongles are found, select the dongle with the largest signal strength.
4. Set up School Information.
5. Input and/or confirm Network Configuration information.
6. Set default Audio Input Levels.
7. Set Audio Output Levels.
8. Set up the equalizer. In most cases the default settings work best in the classroom.
9. Remove the Bluetooth dongle. We recommend the Bluetooth dongle be removed, but this is not required.

Note: All BLE dongles in range of the cell phone will be displayed. Give the application time to gather data before selecting a system to connect to.

Troubleshooting

Reboot

Press button (5 seconds).

Factory Reset Procedure

Press and hold until the Activity Indicator Flashes green (10 seconds) and then Release.

Rescue Mode

Press and hold until the Activity Indicator illuminates red (15 seconds) and then release. Or disconnect power, press and hold the reset button while applying power.

SIP Not Connected

Verify that the SIP settings are correct on the device. Try pushing Settings from the Configure Tab on EPIC again. Pushing settings from the Devices List does not push SIP settings.

No Audio

If there is no audio going through the speakers (bells, paging, intercom, teacher mic), check the audio output to see if there is any audio passing through there. This can be done by connecting a pair of wired headphones to the audio out of the CZA-1300 and playing audio through the CZA-1300. If you hear audio through the headphones, it is most likely not a problem with the CZA-1300 and more related to the speakers or speaker wiring.

Please check to see that AC Power is applied and the AC Power Switch is activated. There is also a fuse accessible through the AC connector that should be checked.
