Components of the HDL300 system
The standard single HDL300 system can be ordered in either a white (HDL300-W) or black (HDL300-B) grill. The shipping box contains the following items:
The Dual HDL300 system includes the same items as the single system with the addition of an extra Integrated microphone and speaker bar and a second Ethernet cable.
The upgrade HDL300 kit can be used to expand the single HDL300 system to a dual configuration. It is available with either a white (Dual-HDL300-W-U) or black (Dual-HDL300-B-U) grill color. The shipping box for the expansion kit will consist of the following items:
A dual HDL300 system can also be constructed from two single HDL300 systems, but there will be additional parts (connect module, remote, power adapter, etc.). Therefore, it is more efficient to construct the Dual HDL300 system with the proper upgrade kit. For more information, see our can more than one HDL300 system be installed to cover a larger space? article.
A list of orderable parts for the HDL300 system can be found in our HDL300 system orderable parts article.
Standard connections of the HDL300 system
Connect module interfaces
Below is a diagram of the front face of the HDL300 system connect module. The following sections describe the connections from the left side to the right.
Power connector (+54C DC)
This port is used to connect to the provided power adapter.
Only use the power supply that is provided with this equipment. Failure to do so may result in electrical shock or other safety hazards.
There are two RJ-45 connector ports on the front of the connect module. For more information on how to use these ports, see our HDL300 system's RJ-45 connectors article.
The HDL300 system connects to your computer through a USB port. For more information on the specifics of this port, see our HDL300 system's USB port article.
Auxiliary input (In) and auxiliary output (Out) Jacks
The connect module also has the option of connecting analog signals using the auxiliary input and output jacks instead of (or in combination with) the USB connector. The default configuration for the auxiliary jacks is for standard line-level audio input and output – as described in this section. The HDL300 system can also have these signals configured for mixed-mode, speaker mode and microphone level outputs. Details for using the auxiliary ports can be found in our using the auxiliary ports article.
Cabling for the HDL300 system
For installation of the product and cabling, follow all applicable country electrical codes, regional codes and local codes or ordinances.
Power adapter and cabling
Only use the power adapter that is provided with this equipment. The power adapter is an integral part of the safe and proper operation of the HDL300 system. Failure to use the provided power adapter may result in electrical shock or hazards or faulty operation of the unit.
The HDL300 system comes with a country-specific power cord to be used with the adapter. If this cord is not long enough to reach to a power outlet, you may use an extension cord or power bar. Only use extension cords, power bars and outlets that properly accommodate the equipment’s polarized/grounded plug. Make sure the extension cord complies with the safety regulations of the country or region. Do not use cheater plugs or any equipment that might defeat the purpose of the electrical ground.
Make sure any power cables used with the equipment are properly bundled, routed, covered or constrained if they cross the floor or pose a tripping hazard.
All HDL300 systems include one 15 m (50’) general-purpose SSTP (screened shielded twisted pair) 26 AWG cable as the PoE cable. It is used to connect the connect module to the HDL300 integrated microphone and speaker bar. However, since the protocol is exclusive for the HDL300 system these ports cannot be directly connected to standard Ethernet ports (IEEE 802.3) on computer networks.
If you need an Ethernet cable longer than the one included in the system, see our I need an Ethernet cable longer than the 50’ (15 m) cable provided article.
Make sure the installation methods follow specific local or country codes or regulations. The cables provided with the HDL300 system are not plenum or riser rated. If the installation is in an air-handling space or between building floors, proper cabling will need to be obtained. For these specific applications, use cables that meet the appropriate safety and regulatory requirements and follow the applicable local or country codes or regulations. Use a trained electrician or expert to install the plenum or riser-rated cabling.
Ethernet Routers and Switches
The communication link between the connect module and an integrated microphone and speaker bar is based on PoE and will not work on standard IP networks. Therefore, these ports should not be connected to Ethernet routers. Additionally, Ethernet network switches (non-mechanical switches) may seem to operate correctly when inserted between the connect module and integrated microphone and speaker bar, but complications or errors may occur during firmware updates or system resets. Therefore, Ethernet network switches should not be used.
Mechanical Ethernet switches can be used if they support a minimum of 10/100 Base-T Ethernet standard and pass PoE power. More information about the uses of Mechanical Ethernet switches can be found in the Can I switch between a single HDL300 and Dual HDL300 system article.
The system comes with a 6′ (2 m) USB cable that connects the connect module to your computer or host system. The cable is a USB A-male (to connect to the host/computer) to USB B-male (to attach to the connect module). If a longer cable is needed, use a USB 2.0 Hi-Speed cable that reaches lengths of up to 16.4′ (5 m). We do not recommend using USB cable extenders or hubs to increase the USB cabling distance, as they negatively affect the audio experience by increasing latency and dropping packets. If necessary, we recommend installing the connect module close to the computer or host device and using a longer Ethernet cable from the integrated microphone and speaker bar to the connect module.
Audio jack cabling
As the signal and cable are single-ended, keeping the cabling length to a maximum of 6 feet to ensure minimum noise is coupled onto the signal. Avoid running noisy cables next to these audio cables so coupling does not occur. Installing the connected equipment next to the connect module will help make sure this happens.
Connecting your HDL300 system
Below are interface connections for a standard HDL300 system configuration.
The HDL300 system is intended primarily to be connected to a USB host (such as a computer) running a UC&C client or SIP dialing software. Below is the connection diagram of a basic system. When connecting the computer to USB, ensure that the playback and recording devices within your operating system and software are set to the HDL300 – Echo Canceling Speakerphone by default.
Voice Amplification Mode has been added to HDL300 and Dual HDL300 audio conferencing systems. With this addition, which is currently available in public beta, the HDL300 systems solve the problem of supporting in-room amplification of an instructor or presenter's voice, while simultaneously providing full-room microphone pickup of in-room voices. Please see the articles below for additional information about Voice Amplification Mode.
External speakers can be used with the HDL300 system. For more information, see the does the HDL300 system support external speakers? article.
Bring your own device (BYOD) options
The HDL300 system does not initially support “bring your own device” (BYOD) options, but it can be integrated with additional equipment to support such scenarios.
For tips on how your HDL300 system can be integrated with BYOD equipment, see the Does the HDL300 system support bring your own device options? article.
Session Initiation Protocol software options
The HDL300 system does not have a built-in SIP dialer, but it can enable SIP dialing with the help of other products. The HDL300 system can provide microphone and speaker functionality for a SIP-enabled device provided the device has compatible ports. For more information, see the Does the HDL300 system support session initiation protocol (SIP) software?
The HDL300 system does not directly support Dante software, but external adapters can be used to configure the HDL300 system to support it. The adapters can be connected through the analog input and output ports of the connect module. Nureva® Console software must have the auxiliary connections configured properly to allow for “Microphone out” (line level) and “Speaker Input.”
For more information, see the is the HDL300 system compatible with Dante software? article.
