SONIFEX Dante Contribution Voiceover Monitor with Talkback - AVN-MTV1
The AVN-MTV1 is an upgrade of the RB-MTV1, adding Audinate Dante AoIP capability to the Redbox voiceover monitor. It is a 1U rack-mount unit designed to be used in voice-over booths, news booths, commentary locations, for continuity announcements and for any other similar applications where voice needs to be added to programme content and then monitored. Talkback, Cue and Program feeds can be taken from the Dante network and monitored.
Sonifex Dante Contribution Voiceover Monitor with Talkback - AVN-MTV1
The AVN-MTV1 has three physical inputs and three physical outputs. It has a mono microphone input on an XLR with physically or remote switched coarse gain and physical variable fine fain control using a multi-turn preset potentiometer to give an overall gain range from +20dB to +80dB. There is also an LF rumble filter, +48V phantom power and level limiting control. A rear-panel multi-turn preset potentiometer allows adjustment of the threshold at which the limiter begins to operate, from -8dBu to +26dBu. There is an indication of the limiter activity using a blue LED and the microphone level is monitored by a simple 5 LED meter. The meter can be configured to either show the MIC signal activity in normal operation (i.e. when TALK is pressed the meter is off) or it can permanently show the MIC activity even when the TALK button is on or the MIC button is off.
There is a balanced XLR stereo input and an auto-sensing balanced analogue/digital input on an RJ45 (StudiohubTM pinout). Each of these inputs are sent to the Dante network.
The Talkback, Cue and Program streams come from the Dante network, as well as the Mic input, and can be mixed and monitored into the front and rear ¼”/3.5mm headphone jack outputs with individual volume controls. Which of the inputs is presented to the headphone outputs can be configured using two banks of DIP switches on the rear of the unit (allowing control over left and right headphone mixes). If a presenter doesn’t like to hear themselves in their headphones when using the TALK button, there is also an option to mute the mic signal to the headphones.
The processed microphone signal is fed to both the main mono balanced output on an XLR and the Main Output Dante stream when the latching front panel MIC button is active – the button illuminates when active.
The main output XLR can be independently switched to be at “Line” or “Mic” level outputs using the rear panel push switch. Setting the output to a microphone level allows the unit to be inserted into the microphone input of a mixing desk. There is an option to permanently enable the MIC button, even when remotely controlled, for occasions when you always want the MIC channel left open. Additionally, there is an option to mix the Cue input as a mono feed to the outputs permanently.
The front panel TALK button is a momentary push switch that routes the processed microphone signal to both the rear balanced XLR Lazy Output and the Lazy Output Dante stream, whilst disconnecting it from the main outputs, allowing the operator to talk to a colleague. This enables the unit to be used as a talkback intercom between two or more studios.
There is a switchable digital/analogue balanced output on an RJ45 which can be used as an exit point from the Dante network.
There is a rear panel remotes connector giving remote control of the two front panel MIC and TALK buttons and opto-isolated tallies of their status.
The unit is powered using Power over Ethernet (PoE) with primary and secondary ports for power and data redundancy. The AVN-MTV1 uses the latest Audinate Dante chipsets so is AES67 and Dante Domain Manager compliant.
There are front panel LEDs to indicate network clock status, AoIP Primary and AoIP Secondary link status, PoE Primary power and PoE Secondary power active.
