TF-18IIH

Professional Audio · TF - Pro Sound System

Features

• High-performance quad-core ARM CorteX-A53 processor (2.0GHz), 32bit/48KHz AD/DA, professional DSP processing, providing excellent high-quality sound.
• Features a 4-input, 4-output audio matrix, with adjustable input sensitivity based on the audio source. Each input supports 48V phantom power and can be individually configured to be on or off, offering flexibility and convenience.
• Input channels support preamplifiers, signal generators, expanders, compressors, equalizers (12-band parametric EQ, selectable 10/15/31-band graphic EQ adjustable, graphic EQ can be used for individual bandwidth adjustment), ducks, AGC automatic gain control, AM automatic mixing (threshold type, gain-sharing type), AFC adaptive feedback cancellation, AEC echo cancellation, ANC noise cancellation, and audio matrix; output channels support equalizers (16-band parametric EQ, selectable 10/15/31-band graphic EQ adjustable, graphic EQ can be used for individual bandwidth adjustment), delays, crossovers, high-pass and low-pass filters, and limiters; based on the feedback detection threshold update method, it has frequency shift + notch filter combined feedback suppression, and can use 24 programmable notch points, which can be freely assigned dynamic/static points and switched automatically/manually.
• It has a ducking function, which automatically ducks the microphone when background music is played. It offers a variety of parameter settings for convenient and flexible use on site.
• It features automatic gain control for the microphone, which controls the dynamic range of the microphone's pickup signal to ensure consistent sound quality at different distances.
• It features intelligent mixing capabilities, including gain-sharing mixing and automatic gate mixing. Input channels can be individually selected for participation in intelligent mixing, allowing for the selection of appropriate mixing modes based on different application scenarios. This effectively addresses pain points such as instability and feedback caused by multiple microphones operating simultaneously.
• Features equalizer functionality, offering both parametric and graphic equalizers. Each input channel offers a choice of 12-band parametric, 10-band, 15-band, or 31-band graphic equalizers, while each output channel offers a choice of 16-band parametric, 10-band, 15-band, or 31-band graphic equalizers. The parametric equalizer supports three types: high-mount, low-mount, and peak filter. The graphic equalizer supports single-point bandwidth adjustment.
• It has a crossover function, offering three filter types to choose from: Bessel, Linkwich-Rayleigh, and Butterworth. It also supports slope settings of 6/12/18/24/32/40/48dB/oct, and the filter is adjustable across the entire frequency band.
• It has an extender function to expand the dynamic range of the signal and is used to eliminate the background noise of the device.
• It has a compressor function to compress the dynamic range of the signal, which is used to compress the size of the output signal.
• It has a limiter function to limit the size of the output signal and prevent the signal from being too large and damaging the sound reinforcement equipment.
• It has a delay function, providing a maximum delay adjustment of 2000ms, which can be used to adjust the delay of each output signal so that each audio signal is synchronized when it reaches the listener's ears.
• It has an echo cancellation function for remote audio and video conferencing, eliminating echoes and increasing voice clarity; the echo cancellation can be selected according to the size of the video conferencing room (three levels are available: small room, medium room, and large room); the noise reduction level is adjustable, with five levels available: 6dB, 12dB, 18dB, 24dB, and 30dB.
• It has a noise cancellation function, which can effectively eliminate environmental noise such as air conditioner noise and fan noise, and improve speech clarity. The steady-state noise reduction level can be adjusted to different levels according to the needs of the site (five levels are available: 6dB, 12dB, 18dB, 24dB and 30dB).
• It has feedback suppression function, with two processing solutions: notch filter and frequency shifter, which effectively solves the acoustic feedback problem.
• Extremely low system processing latency, only 1.1ms.
• The panel features a 2-inch IPS true-color display that shows device network information, real-time levels, channel mute status, matrix mixing status, and other information.
• The panel has a USB interface, which supports multimedia storage and can store recordings or play them back.
