More than one microphone can be used in situations with multiple presenters. > [!NOTE] > **Preparation:** Successful setting up of multiple wireless microphones begins with preparing the software and equipment. ### HDL300 system - Confirm the system has firmware version 2.4.67 or later installed. - Enroll the system into Nureva Console cloud to enable remote management. ### Mixer and cables - A multichannel mixer with XLR input and output is required. Each microphone will require a channel on the mixer. - A [balanced XLR to unbalanced 3.5 mm TRS adapter cable](https://support.nureva.com/docs/using-the-aux-ports-hdl300-and-dual-hdl300) is required. - XLR plug to XLR socket cables are required. Each microphone will require a cable. - The cables, microphones and mixer are purchased separately. - See your audiovisual reseller to purchase the cables and mixer. The Nureva audio system connect modules only support mono and unbalanced audio inputs. > [!WARNING] > Important: > > **Do not** use a Y splitter to add more than one microphone to the connect module. > > - This will send voltage from one receiver to another. > - It will be difficult to achieve the required amplitude from each microphone. > - Damage may occur to one or more microphone receivers. ## Step 1: Connect the system ### HDL300 system 1. Connect the USB cable (provided) to the USB-B port on the connect module. 2. Run the cable to a computer, connecting to a USB-A port. 3. Connect the provided Ethernet cable to the RJ45-1 port on the connect module. 4. Run the Ethernet cable to the RJ45 port on the microphone and speaker bar. 5. Connect the provided power cord to the connect module and plug it into an outlet or a power bar. ### Connect the connect module, mixer and microphones Using the [balanced XLR to unbalanced 3.5 mm TRS adapter cable](https://support.nureva.com/docs/using-the-aux-ports-hdl300-and-dual-hdl300): 1. Connect the cable to the **XLR output** port on the back of the mixer. 2. Connect the cable to the **Aux in** port on the back of the connect module. Using the **XLR to XLR** cables, connect each microphone to the mixer. 1. Connect each cable to an **XLR input** on the back of the mixer. 2. Connect each cable to the **XLR output** on the back of each microphone receiver. 3. Set microphone receivers to **Line level** output if this feature is available. 4. Turn off **phantom power** if the mixer has this feature. 5. Connect the mixer and microphone receivers to the power source using the power cables and power supplies. ### Pair the transmitters to the receivers Ensure each headset or earset is disconnected from the transmitter. 1. Pair each microphone individually. 2. Turn on the transmitter and pair, following the microphone instructions. 3. Set the group and channel according to the microphone instructions. ## Step 2: Adjust volume output on computer The volume setting on the computer affects the amplification level. Start with the volume set at a level normally used in the room. This can be adjusted at any time. | **Windows® computer** | **macOS® computer** | | --- | --- | | 1. Click the speaker icon in the lower-right corner of the taskbar. 2. Adjust the volume with the slider control as needed. | 1. Click the **Volume** control in the menu bar. 2. Adjust the volume with the slider control as needed. | ## Step 3: Adjust the settings ### Nureva Console 1. Go to the sign-in page for [Nureva Console](https://console.nureva.com/sign-in) and log in. 2. Select the HDL300 system that was connected in Step 1. #### Adjust speaker settings 1. Go to **Device settings** and open **Speakers**. 2. Select **Custom** and set the **Bass** and **Treble** settings to **50**. - If there is no distortion during testing, the bass setting can be increased to meet individual preferences. - Reducing the Bass setting can help reduce feedback and audio artifacts. #### Disable sleep mode 1. Go to **Device settings** and open **Auxiliary ports**. 2. Ensure that **Sleep mode** is set to **OFF** by sliding the toggle to the left. #### Enable Adaptive Voice Amplification 1. Go to **Device settings** and open **Adaptive Voice Amplification**. 2. Enable **Adaptive Voice Amplification** by sliding the toggle to the right. 3. Click **Apply** at the top of the device settings dashboard. #### Adjust the aux-in level - Switch the **Aux in** setting to **Line level** to match the receiver. #### Adjust the amplification level 1. Start with the **Amplification level** at **Medium (Default)**. 2. Select the amplification level that provides the best quality voice amplification. ### Nureva App 1. Launch the Nureva App using the desktop shortcut. - An alternative is to open a browser and use a [localhost](http://localhost) connection or the device’s IP address. 2. The Nureva App home page will open. 3. The HDL300 system will be automatically detected. 4. Open the **Settings** menu. #### Adjust speaker settings 1. Open the **Speakers** menu. 2. Select **Custom** and set the **Bass** and **Treble** settings to **50**. - If there is no distortion during testing, the bass setting can be increased to meet individual preferences. - Reducing the Bass setting can help reduce feedback and audio artifacts. #### Disable sleep mode 1. Open the **Sleep mode** menu. 2. Ensure that **Sleep mode** is set to **OFF** by sliding the toggle to the left. #### Add the external microphone 1. Open the **Devices** menu and press the ⨁ button at the top of the dashboard to add a device. 2. Use the drop down menu to choose **External Microphone** device type. 3. Press **Add device** at the bottom of the window. #### Adjust the aux-in level 1. From the **Devices** menu and select the **External Microphone**. 2. Switch the **Aux in** setting to **Line level** to match the receiver. #### Adjust the amplification level 1. From the **Devices** menu and select the **External Microphone**. 2. Start with the **Amplification level** at **Medium (Default)**. 3. Select the amplification level that provides the best quality voice amplification. ## Step 4: Test the amplification ### Test the system 1. Connect each headset or earset to the transmitters. 2. Stand approximately 1 to 2 meters in front of a microphone and speaker bar. 3. Have another person stand at the back of the room or a place where people will be seated. 4. Test each microphone separately. 5. If a UC&C client (e.g., Microsoft® Teams, Zoom) will be used, test the amplification setup with a remote person in an audio or video conference. ### Adjust amplification 1. Set the level (volume or gain) for each microphone channel to **low** on the mixer. 2. Adjust the output level for each microphone. - Adjust the gain on the microphone transmitter or receiver. - Slowly increase the level for the microphone channel on the mixer. - Fine-tune the transmitter and mixer for each wireless microphone until the required output levels are reached. 3. If there is feedback or squelch, lower the gain or dB setting for the microphone transmitter and ensure that **Aux in** is set to **Line level**. - The gain or dB settings when using multiple microphones with a mixer will be different than when using a single microphone.
