Product Information

The AU-A50 is a 2-channel Zone Amplifier designed for audio source equipment such as PC, CD player, and MP3 with output speakers and connection cables. It features an OLED display for current input source selection and volume setting, IR window for accepting IR signals from the included remote control, menu and exit buttons for volume control and muting, and a power button for device control. The rear panel includes LAN and RS-232 ports for PC/laptop connectivity, audio-cat port for audio transmitter connection over CAT5e/6/7, optical and coaxial inputs for audio signal input from devices like DVD player or PS3, RCA IN for stereo audio input from audio source equipment, speaker ports for stereo audio output, IR IN for accepting IR signals from the included remote control, and DC 24V port for power supply.

• The RS-232 pin assignment is as follows: Data bit – 8 bits, Parity – None, Flow Control – None.
• The IR cable pin assignment includes IR signal, power, and grounding connections.

Product Usage Instructions

1. Connect your audio source equipment (PC, CD player, MP3 player) to the input ports using the appropriate cables.
2. Connect your output speakers to the speaker ports using wired cables.
3. Connect your PC/laptop to the LAN port using an RJ-45 cable for Telnet/Web GUI controls.
4. Connect your PC/laptop to the RS-232 port using a D-Sub 9-pin cable for RS-232 controls.
5. If you want to transmit audio over CAT5e/6/7, connect an audio transmitter to the audio-cat port.
6. If you have an audio source device with optical output, connect it to the OPT. IN port using an optical cable.
7. If you have an audio source device with coaxial output, connect it to the COAX. IN port using a coaxial cable.
8. If you have an audio source device with RCA output, connect it to the RCA IN port using an RCA cable.
9. Make sure the included remote control is within direct line-of-sight of the equipment to be controlled and use it to send IR signals to the IR IN port for controlling the device.
10. Plug in the 24V DC power supply into the DC 24V port and connect the adapter to an AC outlet.
11. Use the power button on the front panel or the power button on the remote control to turn on/off the device.

OPERATION CONTROLS AND FUNCTIONS

Front Panel

1. Service: Connect with USB flash driver for firmware update only.
2. OLED: Display current input source selection and volume setting.
3. IR Window: Accept IR signal from the remote control included in the package.
4. MENU: This button has two usage, one for volume control and the other for menu selection. Turn the wheel to adjust the output sound volume before entering into menu selection or press it to enter into the menu selection then turn the wheel to rotate from the selection and press it again to enter or to confirm the selection.
5. EXIT: Press this button to exit from the menu selection. When outside the menu selection press this button to mute the output sound, the LED will illuminate. Press it again to unmute.
6. POWER: Press this button to turn on the device and the LED will illuminate in blue, press it again to switch to standby mode and the LED will furn red.

Rear Panel

1. LAN: Connect from PC/Laptop with RJ-45 cable for Telnet/WebGUI controls.
2. RS-232: Connect from PC/Laptop with D-Sub 9pin cable for RS-232 controls.
3. AUDIO-CAT: Connect from the audio Transmitter over the CAT5e/6/7 extender for audio transmitting up to 300m. It is suggested to use the audio Transmitter within the family line to ensure the transmission of 300m with a sampling rate of 48kHz. When the audio Transmitter obtains RS-232 function it can also control the Zone Amplifier.
4. OPT. IN: Connect from source equipment such as a Set-top-box or PS3 or any other source with optical output for audio signal sending.
5. COAX. IN: Connect from source equipment such as a Set-top-box or PS3 or any other source with coaxial output for audio signal sending.
6. RCA IN: Connect from audio source equipment with an RCA jack for stereo audio input.
7. SPEAKER: Connect from speakers with a wired cable for stereo audio output.
8. LINE IN: Connect from an audio device with a 3.50 pone jack for stereo audio signal input.
9. IR IN: Connect the IR Extender for IR signal reception. Ensure that the remote being used is within the direct line-of-sight of the equipment to be controlled. This IR accepts the IR signal from the package including remote control only.
10. DC 24V: Plug the 24V DC power supply into the unit and connect the adaptor to an AC outlet.

Telnet Control
To access the telnet control under MS Windows, click the ‘Start’ menu and type “cmd” in the search field then press enter. Under Mac OS X, go to Go – Application – Utilities – Terminal See below for reference.

Once in the command line interface (CLI) type “telnet”, then the IP address, and hit enter.

Press “Help” or “?” then hit enter to bring up all available commands.

Note:
Any commands will not be executed unless followed by a carriage return. Commands are case-insensitive. If the IP is changed then the IP Address required for Telnet access will also change accordingly.
