The Model 5414 is a fully professional product that offers the audio quality, features, and reliability required by 24-hour on-air and commercial applications. The four mic/line audio inputs use standard 3-pin female XLR connectors for easy interfacing with balanced and unbalanced sources. The input circuitry features adjustable gain, P48 phantom power, and high-pass filter functions. Configuration of the inputs can be made locally by using pushbutton switches or remotely using the STcontroller application. The input audio signals are converted to 24-bit digital and then transported via the Dante interface. Four digital audio signals can be routed to the Model 5414 via the Dante interface and are then converted to analog.
Four 3-pin male XLR connectors on the unit's back panel provide access to the balanced line-level outputs. The monitor section provides the user with the ability to select any input or output signal, or signal pair, and then monitor them using LEDs meters and a 2-channel (stereo) headphone output.
An Ethernet connection is all that's required to make the Model 5414 part of a sophisticated networked audio system. Dante audio-over-Ethernet has found wide acceptance as an audio "backbone" due to its ease of use, interoperability, excellent audio quality, and wide adoption by a large number of equipment manufacturers. The Model 5414 can serve as an "edge" device for a Dante network implementation, providing high-performance input, output, and monitor resources for applications that need a limited number of channels. It can also serve as a general-purpose "tool" to help expand Dante capabilities to facilities and applications that were initially implemented to support signals in the analog domain.
The Model 5414 is "universal" mains powered, requiring 100 to 240 volts, 50/60 Hz for operation. Standard connectors are used for the audio input and output, Ethernet, and AC mains interconnections. The unit's enclosure mounts in one space (1U) of a standard 19-inch rack enclosure and weighs less than four pounds (2 Kg).
Digital audio data associated with the Model 5414 is interfaced with a local area network (LAN) using Dante audio-over-Ethernet media networking technology. Status LEDs provide a real-time indication of Dante and LAN performance. A major benefit of using Dante is its ability to use any standard Ethernet network implementation, including switches, to directly transport professional audio signals. The Model 5414 supports digital audio signals with a sampling rate of 48 kHz and a bit depth of up to 24. This sampling rate was selected for optimal support of broadcast, production, industrial, and commercial applications.
The signals associated with the four mic/line input channels are converted to digital and then routed to transmitter (output) channels on the Dante interface. Four transmitter (output) channels from an associated Dante-enabled device can be assigned to the Model 5414's receiver (input) channels using the Dante Controller application. These input signals are converted into analog and then sent to the line output circuitry.
The Model 5414 is a general-purpose mic/line input, line output, and monitoring device intended for a variety of audio and audio-for-picture applications that utilize Dante. It's suitable for use in demanding on-air broadcast and live-event applications that require both excellent audio performance and reliable operation. The rack-mounted unit is appropriate for installation in fixed locations, serving the needs of systems associated with stadium, worship, education, commercial, and government facilities. Its lightweight enclosure also makes it suitable for mobile and field uses.
The Model 5414 features an optimized set of controls and indicators that makes it simple and intuitive to use. With the unit's metering and monitoring resources it's easy for operators to obtain optimal performance. And by providing standard connectors for all inputs and outputs, along with direct AC mains powering, setup can be completed in just a few minutes.
The Model 5414 provides four analog inputs that are compatible with microphone and line-level signals. The mic/line input circuitry allows the level of the connected sources to be boosted as required, converted to digital, and then output to an Ethernet network by way of Dante. Each mic/line input can be individually configured to meet the requirements posed by a wide range of sources. The configuration choices can be made either locally or by way of the STcontroller remote control software application. The preamplifier gain of each channel can be selected from among 20 values: 0 dB (line), 10 dB, and 19 through 70 dB in 3-dB steps. A source of P48 phantom power can be enabled to power condenser microphones. In addition, a high-pass filter (HPF) function can be enabled as required to reduce the presence of unwanted low-frequency content typically associated with hum, rumble, or wind noise.
Compatible signal sources include dynamic, ribbon, and phantom-powered condenser (capacitor) microphones. The extended gain range, up to 70 dB, allows microphones with low-sensitivity to perform correctly. The preamplifier gain settings of 0 dB and 10 dB were specifically included to support connection of balanced and unbalanced line-level signals that are commonly provided by professional and semi-professional audio equipment. Typical nominal levels for these sources would be +4 dBu and –10 dBV, respectively. Devices providing these analog signal sources could include audio consoles, wireless microphone receivers, and broadcast playback equipment.
An 8-segment LED meter is associated with each of the four mic/line input channels. The meters are calibrated in dBFS which can assist users in optimizing the preamplifier gain settings so as to provide the best possible conversion from the analog to the digital domain. LEDs display the on/off status of the P48 phantom power and high-pass filter (HPF) functions. For front-panel space efficiency the four mic/line input channels share a common configuration section which includes a 2-digit LED display and four pushbutton switches. The LED display allows the selected preamplifier gain of the mic/line input channels to be observed. The buttons allow rapid local selection of the preamplifier gain as well as controlling the on/off status of the P48 phantom power and high-pass filter (HPF) functions.
The mic/line inputs are electronically balanced (differential), capacitor-coupled, and ESD (static) protected for reliable operation in a variety of demanding applications. Extensive filtering minimizes the chance that radio frequency (RF) energy will cause interference. The inputs are protected from damage should a moderate DC voltage be accidentally connected. The sum of these characteristics makes the mic/line inputs suitable for use in studio and mobile facilities as well as field-deployed environments.
The four 3-pin female XLR connectors associated with the Model 5414's mic/line inputs were specifically located on the front panel. This can eliminate the need for an external I/O or "patch" panel, allowing signal sources and their associated interconnecting cables to be rapidly connected as required. Rather than being "buried" in the back of a rack enclosure the Model 5414 provides convenient access to the mic/line input connectors and their associated configuration buttons, indicators, and displays.
The audio performance of the Model 5414's mic/line inputs is very good. Low-noise, wide dynamic-range preamplifier circuits ensure that input audio quality is preserved. The P48 phantom power source is extremely low noise, allowing optimal microphone operation and imparting little signal degradation. The outputs of the preamplifiers are routed to high-performance analog-to-digital conversion (ADC) sections that support a sampling rate of 48 kHz and a bit depth of 24. A precision voltage-reference integrated circuit helps the ADC circuitry perform highly accurate signal conversion. The audio signals, now in the digital domain, are connected to the Dante interface section where they are packetized and prepared for transport over Ethernet.
The Model 5414 provides four general-purpose analog line-level output channels. Four receiver (input) channels associated with the unit's Dante interface serve as the audio sources. The Dante Controller application software is used to select the sources which are provided by transmitter (output) channels on associated equipment. The Model 5414's line output channels have a maximum output level of +24 dBu. This allows compatibility in SMPTE®-compliant applications where digital audio signals with a nominal level of –20 dBFS will translate to signals in the analog domain having a nominal level of +4 dBu. The line outputs are electronically balanced, capacitor-coupled, and ESD (static) protected. High-quality components, including the important digital-to-analog converters, are used to provide low-distortion, low-noise, and sonically-excellent performance. Robust circuitry provides protection from damage should a moderate DC voltage be accidentally connected, something especially useful in broadcast applications. The line outputs are compatible with virtually all balanced and unbalanced loads with an impedance of 2 k ohms or greater.
Input and Output Monitoring
A flexible yet easy-to-use monitor section offers the ability to listen to and visually observe the level of the audio signals that are associated with the four mic/line input channels and the four line output channels. A mode configuration choice allows monitoring of either a single audio channel or a pair of audio channels. This can be valuable when monitoring monaural or stereo (dual-channel) signals. A 2-channel analog output supports the connection of a pair of stereo headphones. For application flexibility the headphone output can also be interfaced with inputs on amplified loudspeakers or a power amplifier associated with monitor loudspeakers. A rotary control allows the level of the headphone output to be adjusted.
For convenience, two ¼-inch 3-conductor (stereo) phone jacks, one located on the front panel and one on the back panel, are provided. The same 2-channel signal is routed to both the front and the back headphone output jacks. However, whenever the front jack is utilized the jack on the back panel will automatically mute. This mute function can be useful when the jack on the back panel is being used to interface with inputs on loudspeaker systems. Automatic muting of the loudspeakers will occur whenever a pair of headphones is plugged into the jack on the front panel, a feature especially important for on-air applications.
Two 8-segment LED meters display the level of the signal or signals that are selected for monitoring. The meters are calibrated relative to the digital domain (dBFS), directly reflecting the signal level in the Dante transmitter (output) and receiver (input) paths.
The Model 5414 uses standard connectors to allow fast and convenient interconnections. 3-conductor male and female XLR connectors and 3-conductor ¼-inch jacks are used to interface with the analog input, analog output, and headphone output audio signals. The unit connects to a local area network (LAN) using a standard 100 Mb/s twisted-pair Ethernet interface. The physical interconnection is made by way of a Neutrik® etherCON RJ45 connector. While compatible with standard RJ45 plugs and patch cables, etherCON allows a ruggedized and locking interconnection method that's suitable for harsh or high-reliability environments. Three LEDs on the back panel display the status of the network connection and Dante interface. The Model 5414 requires 100-240 volts, 50/60 Hz mains power for operation which is connected by way of a standard detachable mains power cord. The light-weight aluminum enclosure mounts in one space (1U) of a standard 19-inch rack enclosure.
Future Capabilities and Firmware Updating
The Model 5414 was designed so that its capabilities can be enhanced in the future. A USB connector, located on the unit's back panel, allows the application firmware (embedded software) to be updated using a USB flash drive.
The Model 5414 uses Audinate's Ultimo™ integrated circuit to implement Dante. The firmware in this integrated circuit can be updated via the unit's Ethernet connection, helping to ensure that its capabilities remain up to date.
