GS-CU001B/1 MKII - 3 users, with electronic balancing

Glensound GS-CU001B is a commentary unit for three users, and features three mic/line inputs – each with independently switched +48V phantom power. GS-CU001B/1 MKII has electronically balanced audio inputs and outputs, however GS-CU001B/3 MKII is available to order and has transformer balanced I/O.

The top panel of the commentary unit has controls for source channels A and C, COMM level control for channels A and C, on switch for microphone, and talkback (TB) switching for channels A and C. Panel indicators display the status of each independent talkback circuits. When talkback is active the channel feeds no signal to either direct or mixed outputs. Glensound note “In many cases, the three talkback circuits will have a corresponding return talkback signal fed back to three of the SOURCE inputs. The talkback circuits are
therefore labelled 3, 4 and 5 in order to provide a loose association with source inputs 3, 4 and 5 under these circumstances. However, the talkback send outputs are entirely independent of the source inputs and may be used in any configuration required.” Headphone routing switches and labelling areas are also positioned on the upper facing panel.

The front facing panel houses 6.35mm jack headphone outputs for bother users and guest. It also houses three channel inputs by way of 3-pin XLR – each with independent phantom power switching and trim control.

The rear facing panel houses all audio I/O connectivity including source inputs via five balanced mono 3-pin XLR inputs; 9-18V DC power input by way of four-pin male XLR; Talkback send outputs via three balanced mono, 3-pin XLR connections; and three direct outputs. Three switches allow the setting of switch mode, bandpass filter, and direct output level selection.

VITA - Single user, beltpack

Vita is a compact belt pack, single user commentary box designed to connect to a DANTE/AES67 audio network, providing a single user with headphone and microphone interface and single talkback circuit. The two audio inputs and two audio outputs of the Vita are DANTE/AES67 network audio circuits. Remote control of mic on/off, gain level functions, and configuration is via a Windows 10 application.

The front panel of the Vita features two source level controls. These two potentiometers adjust the headphone volume of the two input circuits being received from the DANTE network. There are two input routing controls that control the routing from the headphone source to either the left only, right only or both sides of the commentator’s headphone. One yellow talkback button and 1 red program button route the commentator’s mic to the output of the Vita - either channel 1 or 2 of the DANTE network. The momentary/latching/intelligent operation of these talkback buttons can be set using Glensound’s Vita Controller software. The feedback pot and talkback switch are also used to adjust the audio level of the commentator’s microphone in their own headphones. This feedback adjustment has no effect on the outgoing audio level and is only used for confidence monitoring (sidetone). On the right side of the panel there are four green LED PPM indicating the output level of the main programme circuit. The -12 to +6 scale shows the output level in dB, with each LED covering a 6dB range.

The left side panel of the Vita shows four green LED PPM indicating the output level of the main program circuit. This is to assist the user when the Vita is being used clipped to a belt. A single blue LED indicates the Vita is receiving power.

Inferno - Single user

Glensound Inferno provides the facilities required by a single commentator, connecting to a DANTE network. The system is scalable by adding extra Inferno units to the network. The unit contains a single microphone or line input to feed out to the network and a headphone amplifier with seven inputs fed from the network. Remote control of input gain and switching functions is by a web browser interface. DANTE-capable 'break-out boxes' are available which can connect directly to the Inferno or via an Ethernet network.

Designed for live, on-air broadcast applications it has multiple redundancy capabilities, with four possible sources of power; the inbuilt AC power supply, two POE connections and one external DC input. There are fully redundant network connections for both copper and fibre circuits.

DANTE is a software and hardware solution, offering high-performance audio distribution over standard IP networks, supporting hundreds of simultaneous channels of uncompressed audio with low latency and accurate synchronization. For further information, DANTE networking basics. In a DANTE network, the DANTE Controller web interface controls audio routing. Any DANTE input can be routed to any other output on the network, or to multiple network output points.

The Inferno can be used in conjunction with other manufacturer's equipment when connected to a DANTE audio network. but can also be used outside of a dedicated DANTE network when connected to Glensound's DARK Series 'break out boxes'. This connection can be direct or across a structured network. The DARK88 thus 'allows all of the audio inputs and outputs to be located in a separate location to the Inferno'. When connected to a DANTE network, 'sources and destinations can be configured from any part of the network using the free DANTE controller software. Details are available at www.audinate.com'.

The four network connections of the Inferno can be configured as a switch. In this configuration, if the primary and secondary redundant SFP/fibre slots have been used as the network link, the RJ45 connections can be used to loop out to further local Inferno units or other DANTE devices, which will all be shown separately on the network within the DANTE Controller configuration utility.

On the vertical front panel there are two sockets for the headphones; both are 3-pole jack sockets, one is a 3.5mm type, the other 6.35mm. There is also a 3-pin, female, XLR connector for the microphone/line input, which has a compressor-limiter system, applying 'a variable rate compressor to the input peaks so that no clipping occurs, without affecting the rest of the audio signal'.

On the rear panel, push-buttons are used together with LED indicators to set the input mode. One button toggles the the coarse input gain between microphone and line settings. Two LEDs show which is selected. A second button turns the 48V microphone phantom power on and off. It cannot be turned on if the gain is set to line. A second block of two buttons, up and down, and three LED indicators set the fine gain. The actual gain is not shown, but each button-press changes the gain by about 0.33 dB. The 'Lineup' LED indicates when the gain is in the factory pre-set line-up condition.

The next block of LEDs indicate the status of the power inputs, with one LED each for AC mains, external DC and primary and secondary power over ethernet from the copper Ethernet ports. There are connectors on the lower part of the panel, an IEC inlet for AC, a coaxial type for the DC input and two Ethercon types to take RJ45 Ethernet connectors. Two SFP slots are provided for optional primary and secondary fibre interfaces using accessory SFP modules. Each of the latter four have an LED to indicate that there is a network activity on the connection. A mini-B USB connector is provided for updating firmware in conjunction with 'Reset' and 'Update' buttons.

The sloping part of the upper surface is divided up into ten blocks with seven of them are associated with the seven inputs for cue or talkback. Each block is similar, having an area for marking the nature of the source, a rotary control which sets the level of that signal in the headphones, a 'left-centre-right' (L-C-R) push-button and a talkback button. The L-C-R button routes the associated headphone source to either the left only, right only or both (centre) of the commentator’s headphones. A separate block in the centre of the panel has a stylised picture of a headset, with an LED in each earpiece. The first press of an L-C-R button causes the LEDs to illuminate and show the routing for the source concerned. Subsequent presses cycle through the available routings. The talkback button routes the commentator’s microphone to the corresponding output of the Inferno - channels 1 to 7 of the DANTE network. The operating mode of the buttons - momentary, latching, intelligent lever key for example - can be set using the web page interface.

An 'L'-shaped block contains a vertical column of LEDs in the centre of the panel, forming an 'accurate 15 LED PPM indicating the level of the main, on-air, output. The 1-7 scale is a traditional BBC PPM scale used extensively throughout Europe and the -12 to +12 scale shows the output level in dBs'. Each LED covers a 2dB range. To the lower right a rotary control sets the level of 'sidetone' (the output of the commentator's microphone) heard in the headphones, routed by an L-C-R button as described previously. Between the PPM and the 'sidetone' control there is the 'ON AIR' button, which routes the commentator's microphone to the channel carrying commentary over the DANTE network. The operating mode of the button may be set using the web page interface. The remaining block contains a single LED which illuminates to show the unit is on.

The Inferno contains a web server, 'allowing remote functionality to an engineer from any PC connected to the network via any web browser' by means of the 'Inferno Controller'. Remote control of the microphone/line input gain is available, as is remote configuration of each (talk) push button on the unit 'to be on/off latching, momentary (push to talk), always on, and off when pushed (cough), or in an intelligent mode where a short press latches or a longer press is just momentary'. The push buttons on the rear panel can also be locked. Network settings can be configured, headphone routing set and locked. The headphone levels can be prevented from being turned fully off and sidetone control can be set on or off. A further page offers 'channel effect configuration'. This controls the interaction between all the push buttons on the top panel. 'For example, pressing a talk button would typically supress the microphone 'on-air' output, which would then return when the talkback is released. This button interaction is all configurable'. There is also 'a PPM meter available across the network on Inferno Controller showing the same -12 to +12dB PPM scale as the top panel'.

MinFerno - Single user

MinFerno is a newer and smaller version of Glensound’s popular Inferno network audio commentary box. It is designed for a single commentator or announcer to use, and like the Inferno, it provides a commentary microphone amplifier and compressor limiter circuit. MinFerno is ‘easy to use’ for those commentators who would rather be talking about the sport or subject they’re commentating on. It has been built to be rugged and robust, and therefore it makes it a reliable piece of broadcast equipment for the busy engineer.

Four versions are available within the MinFerno range, with each model having either no, or a number of talkback channels:

The SFP fibre slots are standard networking ports that accept standard SFP modules, giving the user the option of using the fibre and connector style they wish to use. The primary and secondary network circuits allow for ‘glitch free redundancy’ across both the Fibre and Copper network interfaces. Two CAT6 connections by way of Neutrik Ethercon are provided to allow copper connections to local network switches to carry the Dante/AES67 audio. Two connections are fitted to allow redundant circuits to be used if required, with both of these connectors accepting a PoE power source for providing the power to the MinFerno.

One pair of push buttons selects the input type of the front panel, 3-pin XLR to be either microphone, line or microphone with 48V phantom power. Three LEDs indicate which input mode is selected. Two push buttons are used to alter the gain of the input whilst LEDs indicate if the gain setting is above or below Glensound’s pre-configured ‘lineup’ levels. The front panel PPM provides an accurate indication of the input level. The gain can also be altered remotely by a web browser pointing at the MinFerno's web page.

The upper facing panel houses up to five rotary headphone volume controls, with four of these being connected to four incoming audio circuits from the Dante/AES67 network. These are normally used for such sources as mixed programme or cue, talkback to director, talkback to producer, or talkback to engineer. A fifth front panel rotary headphone volume control is ‘sidetone’.

Each of the five headphone volume controls has an associated left ear/right ear/both routing switch located next to the volume knob. This single push button switch routes the associated source to just the left, the right, or both channels of the stereo headphone amplifier. Two LEDs on the front panel indicate MinFerno’s current headphone routing arrangement to enable the commentator to know how they are routing a circuit the first time a routing switch is pressed. The next time the routing switch is pressed then the next routing option is selected.

Depending on model, there are up to four large, illuminated buttons; one for programme and up to three for talkback. These switches route the outgoing microphone circuit onto up to four different Dante/AES67 network audio circuits. The momentary or latching operation of these switches, and the interaction of these switches (i.e. pressing a talkback switch mutes the main mic) can be fully configured via the web page. The audio input level is indicated on the 15 segment PPM meter.

Glensound MinFerno can be powered from any of three different sources including PoE on the Primary CAT5 network link, PoE on the Secondary CAT5 network link, or External 12V DC. Four rear panel LEDs show the availability of the 3 power sources.
