MIC 1 / AUX / PLAYER LEVEL CONTROLS Rotary knobs for adjusting volume levels of selected channel.
BASS & TREBLE TONE CONTROLS Tone controls provide attenuation of bass and treble response. The flat position is obtained when the knobs are set to middle position. Turn the knob clockwise to raise tone level approximately +7.5 dB for bass and +10 dB for treble; turn counter-clockwise to lower tone level by approximately -7.5 dB for bass and +10 dB for treble.
USB DRIVE INPUT Music player is confirmed to handle USB drives formatted in FAT32, with a maximum capacity of 32GB
AUX INPUT The device includes a 3.5mm stereo input for connecting an auxiliary audio source. To use this input, select the “Line In” option on the media player. The volume for this input can be adjusted using the “PLAYER” level control knob on the front panel or via the app on a smartphone or tablet.
MASTER VOLUME Rotary knob for adjusting master volume.

MAIN POWER CONNECTOR AND FUSE Power connector for mains power, combined with fuse holder. Use only the same type of fuse that is written on the device.
POWER SWITCH Switch amplifier power ON or OFF.
AMPLIFIER OUTPUT Audio outputs for Low impedance (2 ) and 100 V speakers. Make sure that the correct speaker output is enabled by using the DIP switch located next to the microphone input. Only one output can be used at a time. Especially for small background music systems, we recommend using 2 output in order to perform the best audio quality and frequency reproduction. Low Z output allows using 8×16 loudspeakers or 4×8 loudspeakers connected in parallel. Amplifier’s 2 output designed without output transformer and has traditional 20 Hz-20 kHz frequency responses to sure the best possible audio quality for background. Pay attention to wiring on low Z output! Please use a minimum of 1.5 mm2 cables to connect speakers to a short distance. Depending on audio line length, cable diameter must be increased in order to minimize voltage drop on cable.
LINE LEVEL AUDIO OUTPUT RCA stereo output for connecting device to external audio amplifier or other equipment. The audio level in this output is not affected by the Master volume.

The amplifier can be powered using an external power source that provides voltage from 24 V to 36 V DC power. This is useful for emergency situations or when AC mains power is not available. Voltage in DC input affects the maximum amplifier’s power. Please check the table above. It shows the relation between the amplifier’s output power and the DC input voltage.

AUX INPUT RCA stereo input for connecting external audio source.

MIC INPUT Phoenix connector for balanced microphone connection.

PHANTOM POWER AND INPUT PRIORITY MIC input can provide 24 V phantom power for condenser microphones. This input can also have a priority over other inputs.

EMERGENCY MUTE When 24 V DC current is supplied to EMG MUTE input, all device inputs (except microphone) will be muted. This is useful when using device combined with external alarm systems.
OUTPUT IMPEDANCE SELECTOR This selector sets up amplifier outputs depending on audio system type. 100 V mode enables output transformer and sets up amplifier circuits to adjust and amplify audio optimized for 100 V speaker lines. 2 mode turn off the 100 V output transformer, in order to connect speaker lines directly from the power amplifier stage. This mode ensures the best amplifier performance and also enables 20 Hz-20 kHz frequency reproduction.
WIFI ANTENNA Connector for WiFi network antenna. An antenna is included with the device.
ETHERNET CONNECTOR Allows connect to the local Ethernet network. The device uses DHCP to assign IP addresses. The streamer WEB interface also offers the ability to disable DHCP and use a static IP address. However, we highly recommend using DHCP. If you require a static IP, we suggest configuring the router to assign the same IP address based on the streamer’s unique MAC address.
