how to install Poly SHS1890-25/DH Headset Amplifier

• Prepare and position: Place the amplifier on your desk near your workstation and within easy reach of your headset and computer or phone system. Ensure the environment is stable to avoid accidental knocks during calls.
• Connect your headset: Insert the headset plug into the amplifier’s headset jack, following the connector type that matches your headset. Confirm a secure fit so audio passes cleanly through the device.
• Connect to your audio source: Connect the amplifier to the device you use for communication, such as a desk phone, computer, or UC-enabled device, using the appropriate cable or interface per your setup. Ensure that the chosen input/output path aligns with your workflow.
• Power and test: If the amplifier requires power, connect it to a powered USB port or power supply as specified by the manufacturer. Power on, then place a test call to verify microphone pickup, speaker output, and overall clarity.
• Adjust for comfort and control: Use the dedicated volume control to set comfortable listening levels and the mute switch to manage on-call interruptions. If you notice symmetry issues between input and output, adjust the gain and test again to achieve balanced audio for both parties.
• Optimize for UC platforms: For optimal results, check your UC or telephony platform’s audio settings to ensure the amplifier is selected as the active headset device. Run a quick test call and verify microphone pickup and speaker playback across typical scenarios (headset-only, speakerphone, and mixed environments).
