Description
Analogue Four-Channel Diversity Receiver
The innovative wireless microphone systems of the ACT-300 series are the result of many years of extensive experience in the design and manufacture of microphone and radio systems. The four-channel receiver comes in a robust 1U EIA standard 19 “metal housing. With a backlit LCD display instead of a conventional LED variant, the receivers of the 300 series provide more user-friendliness and a professional appearance. Thanks to the PLL-Synthesized technology, the radio systems are convincing Outstanding RF stability between transmitter and receiver. The ACT-314B four-channel receiver also has a practical volume control per channel for individual control of the individual channel volume. The ACT-300 series combines professional properties, user-friendly operation and excellent quality at an affordable price.
Specifications
Features:
- Robust metal housing EIA standard 1 x 19 “RU.
- Receiver supplies supply voltage for optional antenna systems / boosters to expand the reception range and increase reception stability.
- The backlit LCD display shows frequency code, RF & audio level, transmitter battery indicator, diversity signals, interference warning indicator, user name, group, channel, squelch level and lock status.
- Bright green display in work mode, automatic dimming of the display in standby mode.
- Balanced XLR and unbalanced 6.3 mm jack audio output socket. Output level switch (mic / line signal) and single / sum signal switch for multi-channel receivers.
- Volume control for individual control of the individual channel volume.
- UHF-PLL synthesizer with high stability and low side emissions. Up to 112 programmed channels plus a user-defined group with up to 8 freely programmable channels.
- The world’s first ACT ™ (Automatic Channel Targeting) offers precise and fast frequency synchronization between the receiver and transmitter.
- Improved RF filter elements and circuitry for lower sensitivity to noise and more interference-free channels.
- Dual squelch setting for NoiseLock and pilot tone. Transmitter can be switched on / off at any time without causing disturbing noises.
- Set reception sensitivity (SQ) using the industry-unique interference warning display. Higher sensitivity for a wider reception area, lower sensitivity to reduce interference.
- External switching power supply and input socket for operation with 12 ~ 15V DC.
