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.

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.

PARADISO - 3 user

Designed for live on-air broadcast applications the Paradiso has been designed with multiple redundancy capabilities. It has 4 possible sources of power (mains, 2x PoE, and external DC) and it also has fully redundant network connections for both Copper and Fibre circuits. Paradiso contains three mic/line inputs and three headphone amplifiers, each with 8 mixable audio inputs and their own level controls. Remote control of input gain and switching functions is by way of Windows 10 app. The Paradiso can also be used in conjunction with other manufacturer's equipment when connected to a DANTE audio network, and it can also be used outside of a dedicated DANTE network when connected to Glensound's DARK or AoIP Series 'break out boxes'. This connection can be direct or across a structured network.

The four network connections of the Paradiso 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 Paradiso units or other DANTE devices. These will all be shown separately on the network within the DANTE Controller configuration utility.

On the vertical front panel of the Paradiso there are three sockets for the headphones. The standard 6.35mm stereo jack socket can drive headphones with impedances between 32 and 1000 Ohms. The Paradiso has a circuit that automatically adjusts the output level to match the impedance of the headphones used. There is also three 3-pin, female XLR microphone/line input connectors, which have compression/limiting when mic is selected. A variable rate compressor is applied to the input peaks to ensure no clipping occurs. This also functions without affecting the rest of the audio signal. There are three yellow push switches for input type. These change the input type between mic, mic with +48V phantom power, and line. Associated LEDs indicate the current state. There is one Aux input present which accepts an unbalanced stereo circuit on 3.5mm jack socket. The front panel also has three gain control rotary shaft encoders that alters the input gain being applied. When adjusted the ePaper display above indicates, in dB, the current actual gain being applied. Turning the control quickly will make the gain adjust in larger steps and turning slowly makes the gain change in finer resolution. It is possible to disable this gain control from the control app.

The top panel of the Paradiso houses an On-Air LED in the top left corner. This illuminates when any one of the three ‘MIC ON’ switches are switched on. In the opposite corner there is a blue LED that indicates when the unit is connected to a suitable power source, and when the internal processor is working. Across the top of the upper panel there is a PPM meter which shows the output level of the mix of the three commentator’s microphones. Below this there are three red ‘MIC ON’ buttons which turn the commentator’s microphones on and off.

The Paradiso is fitted with ePaper displays, with each display providing information that would normally be associated with the headphone level and pan control and the talkback switch. The graffiti provides an indication of what the associated audio source or destination is. The top ‘bar’ of the ePaper display provides a visual indication of the position of the associated volume control, whilst the bottom ‘bar’ of the display provides a visual indication of the current panned position of the source.

Twenty-four coloured knobs provide the level and panning of the associated input audio source. Turning the knob clockwise/anticlockwise increases/decreases the level. The knobs are used to pan the audio source between the left and right ears of the commentator’s headphones. The bottom section of the ePaper display indicates the current panned position. The talkback buttons also present on the top panel route the commentator’s microphone to the associated talkback output.

On the rear panel there are five standard balanced audio outputs/inputs on 3-pin XLR. These are fed internally from the DSP and can be completely independent to the DANTE audio circuits as they do not require the DANTE network to operate. There are two fibre network interfaces fitted, one Primary and one secondary on Neutrik Opticon connectors. The Paradiso is also fitted with a primary and secondary Neutrik Ethercon connectors that provide the copper network interface. In the top right corner of the rear panel is a D9 socket that provides 1x AES3 input and output giving two channels of audio. The sample rate of this AES3 circuit matches, and is locked to the DANTE network. A pair of GPO (general purpose outputs), and a pair of GPI (general purpose inputs) are also provided. There are two USB sockets on the rear panel USB. One is used for updating firmware to the main processor and the other is used for updating firmware to the processor controlling the front panel. There is one blue identify and reset button which is used for updating software. A 3-pin IEC mains inlet accepts a mains input range of 100-240 VAC, and a two-pin barrel type DC input connector. It is designed to accept a +volt DC input between 9-15 volts.

The Windows 10 App is called GlenController and allows full remote control and set up of all the features of the Paradiso, see GLENSOUND GLENCONTROLLER SOFTWARE. GlenController connects to the Paradiso via the same network as the Dante audio circuits and provides a reliable redundant control system via both the primary and secondary network interfaces, meaning that even if one of the two networks were to become disconnected, the remote control would continue to work. GlenController can connect to multiple Paradiso units, and multiple instances running on different PCs can connect to a single Paradiso. There is an option to lock out other users from controlling a Paradiso and this facility can be password protected. For users regularly using the units at different events and functions settings can be saved, and assigned names for quick recall and imported/exported between different Paradiso hardware units.

GlenController provides day to day operation such as turning mics on/off adjusting microphone gains, setting PPM levels, viewing/ adjusting headphone level controls and changing graffiti on the ePaper displays. It also provides full facilities to allow complete customisation of the Paradiso’s features including, but not limited to: Switch operation settings including momentary, latching, and cough. Switch interaction - pressing TB switch turns off Mic; GPIO setup, headphone volume attenuation, routing/mixing audio circuits to the Dante/AES67 network, routing/mixing audio circuits to the analogue and digital outputs, routing/mixing audio circuits from the Dante/AES67 network, and routing/mixing audio circuits from the analogue and digital inputs.

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.
