DHD’s Toolbox configuration software gives TX2 operators or their support technician the freedom to create the mixer layout that best fits the required workflow. This can be achieved via an intuitive graphic control interface and then locked. The number and size of faders can be configured, buttons can be assigned with the required functions and peak meters can be configured to show specific channel signal levels.

The TX2 connects to a core processor or concentrator along a single network cable which also carries all audio and control signals, plus power, up to 100 meters. The mixing panel can be integrated with XC3 or XD3 cores in isolation or as part of a larger mixing system and does not require a PC for operation. Frequently used connectors for projects such as for online interviews or audio dubbing can be accessed on the TX2’s 5 cm high rear panel. These include an XLR microphone input, a 6.3 mm stereo headphone output, an analog stereo speaker output and a 3.5 mm mini-jack I/O which can double as a cellphone port. With its built-in talkback microphone and loudspeaker, the TX2 can also function as talkback unit or monitoring controller.

Also on demonstration at MPTS 2023 will be the DHD DX2, RX2 and SX2 modular mixing consoles.

DHD DX2 compact desktop mixer

The DHD DX2 is compact desktop audio mixer designed for use wherever space is at a premium. It is based on the 52-1214A central module plus the 52-1220A expansion unit. Four faders plus a dedicated section for setup, monitoring and talkback are incorporated in the central module. The 52-1220A fader module has six professional grade 100 mm motorised faders with dust-protection. Each channel also incorporates two control buttons, a UTF8-supported channel identifier, adjustable gain settings, an input channel meter and programme/off-air selection. Each fader can support a second layer. Both DX2 modules are equipped with a user-configurable 7.8 inch multi-touch screen for viewing fader and central control parameters. The DX2 can be connected to all DHD XC3 and XD3 cores.

DHD RX2 6-fader mixing console

The RX2 is a mixer is based on two modules – central and fader – which can be combined to match a wide range of radio and TV production environments. Configuration scales from small production units with 6 or 12 faders to large consoles with up to 96 faders. Each module has a dedicated high brightness 10.1 inch touch display. The RX2 central module (52-5810) provides the main audio I/Os plus a direct microphone input and a stereo headphone output. Loudspeakers can also be driven directly from this module. The fader module (52-5820) includes six dust-protected 100 mm track-length motorised faders. Every fader channel is augmented by a rotary encoder and two pushbuttons.

DHD SX2 desktop mixing console

DHD’s SX2 is a modular mixing console based on a four-fader central module (52-5614). Each SX2 unit is a standalone desktop device which can be chained with others to create a single mixing desk. The central module gives access to the most important audio inputs and outputs. A microphone input and headphone output are also included. Loudspeakers can be connected directly to this unit. Also available is a fader module (52-5620) with six motorised faders. Central and fader modules each incorporate a 10.1 inch multi-touch display showing relevant configuration and operating parameters. SX2 features can be extended simply by adding optional license codes to the DSP core. This allows extra faders, busses and clean-feeds. Functions such as loudness metering, profanity delay and talkback to other DHD mixers are also supported.
