Citronic TU4-C Quad PLL Tuneable UHF Wireless Microphone System - 2 x Handheld & 2 x Bodypacks
The Citronic TU4-C is a PLL Tuneable Quad Channel UHF True Diversity Wireless Microphone System supplied with two handheld transmitters and two bodypack transmitters with neckband and lavalier microphones.
The Citronic TU4-C is the flagship configuration in the TU-series wireless microphone range, combining two handheld microphone transmitters and two bodypack transmitters in a single four-channel system — providing the maximum possible flexibility for demanding stage performances, theatrical productions, conferences, panel events and any other application requiring four simultaneous wireless microphone feeds.
With two vocalists or presenters on handhelds and two performers or speakers using hands-free headset or lavalier microphones, all operating simultaneously from a single 1U rack-mount receiver, the TU4-C provides a complete, professional and ready-to-use four-channel wireless solution that would otherwise require multiple separate systems.
Intelligent Channel Management Across Four Channels
At the heart of the TU-series is a sophisticated channel management system that handles all four channels with equal precision and ease. The full-colour TFT display and rotary encoder on the receiver's front panel allow complete programming of carrier frequency, EQ settings, transmission power and display backlight colour for each of the four channels independently — making it straightforward to identify and manage four different transmitters simultaneously. Each channel wirelessly syncs to its paired transmitter via IR connection, automatically configuring each transmitter to match its receiver channel settings without the need for manual adjustment. An auto frequency sweep function identifies and locks onto the clearest available frequencies across all four channels for reliable, drop-out free operation throughout even the busiest RF environments.
Two Handheld & Two Bodypack Transmitters
The TU4-C is supplied with two full metal handheld microphone transmitters, each fitted with a high-quality dynamic capsule for clear, natural vocal reproduction on stage and in spoken word applications. Two compact and lightweight bodypack transmitters — each weighing just 74g without batteries — are also included, each supplied with both a neckband microphone and a lavalier microphone, giving each bodypack user the flexibility to choose their preferred microphone option. All microphone connections feature fully balanced signal connections for clean, interference-free audio across all four channels. A wireless range of up to 60 metres provides ample freedom of movement for all four performers or presenters simultaneously. Two AA batteries are supplied per transmitter.
Flexible Connectivity & Tuning
Each of the TU4-C's four channels features an independent 7-band EQ for precise tonal shaping to suit different voices, microphone types and acoustic environments. Individual XLR outputs per channel allow direct connection to mixing desks and PA systems, whilst a single mixed jack output provides a convenient alternative for simpler setups. Twin BNC antennas with true diversity reception and internal antenna distribution can be connected at the rear of the receiver or repositioned to the front panel when rack-mounted using the supplied BNC extension cables. The system operates licence-free within the 863–865MHz UHF band in the UK and EU, with additional channel 65 frequencies (823–832MHz) also available with a PMSE licence.
