Mipro MI-909RT Set 480-544 MHz In-Ear Monitoring-Set

The MI-909 is a digital UHF InEar Monitor system consisting of the MI-909R receiver and the MI-909T transmitter. Thanks to new digital encryption technology, unique sound and outstanding transmission stability, MIPRO lives up to its name as a pioneer with this new and innovative IEM system. With a transmission range from 20 Hz low frequency, advanced DSP technology and digital diversity antenna signal management, the MI-909 outperforms any analog IEM to date. The transmitter (MI-909T) and the receiver (MI-909R) come in a robust metal housing with magnesium alloy and impress with first-class features on stage and in other applications.

Features of the complete MI-909 system:

• Stable PLL circuit enables interference-free use with larger stage setups
• UHF band operation with 64 MHz switching bandwidth
• Automatic synchronization of the receiver frequency with the transmitter frequency thanks to the patented MIPRO ACT™ function (Auto Channel Targeting)
• Reception range of up to 100 m
• Resistant to interference from Bluetooth, WLAN and 2.4 GHz radio transmissions
• Digital encryption for secure signal transmission protects against unauthorized listeners
• Constant digital transmission means there is no signal attenuation over long distances
• Crystal-clear sound and very good speech intelligibility

Features MI-909R receiver:

• Single-channel in-ear monitor receiver
• Ultra-compact, lightweight and robust magnesium housing
• The digital diversity receiver technology prevents dropouts and increases the reception range. Constant digital transmission means there is no signal attenuation over distance
• The bright LCD display shows battery status group, channel, RF output power, mute, stereo signal, lock and error information
• Stereo, mono or mixed output signal selectable
• Extended operating time with 2 AA alkaline batteries

Features MI-909T transmitter:

• Robust metal housing EIA standard 1/2 19" RU
• Bright LCD display shows battery status group, channel, RF output power, stereo/mono settings
• All settings can be made quickly and intuitively using a single rotary knob
• Balanced and unbalanced line-in
• 2 selectable audio input settings (microphone/line signal)
• Unique 256-bit encryption guarantees secure signal transmission and protects against unauthorized listeners
• Monitor headphone connection 6.3 mm jack
• RJ-11 MIPRO ACT BUS interface
• Adjustable transmission power (high/low/off)
