Product Overview
One wireless platform, two microphone styles - pick the form factor that fits your table.
Each TWM-118 set combines a rack-mountable 8-channel receiver with eight wireless desktop conference microphones. The system transmits in the UHF 640–690 MHz band using PLL frequency-synthesis tuning, with infrared pairing and manual frequency selection for quick on-site setup. Automatic channel scanning finds clean frequencies, and 200 selectable channels let several systems run side by side without interference.
The receiver uses eight antennas and auto-tracking tuning to stay stable on any working frequency. Each channel carries a unique ID, so up to three complete systems - three receivers and 24 transmitters - can operate simultaneously in the same venue.
Every microphone unit features:
- A 14 mm gold-plated condenser capsule with cardioid pickup for clear, faithful voice reproduction
- A removable 3.7 V 18650 battery with 10–15 hours of continuous operation
- A USB-C charging port on the base - charge while in use, with intelligent cut-off when full
- A touch mute key with on-screen mute/speaking icons, and long-press power on/off
- A bright LCD showing battery capacity and working frequency
Two Models,One Platform
Both models share the same receiver and microphone electronics - the difference is the stem
TWM-118Q8 - Short-Rod Set
- 8 × short-rod condenser microphone units in each set
- 240 mm square-tube stem, full-metal construction
- Touch mute key with real-time mute/speaking icon display
- Removable 18650 battery, USB-C charging on the base
- LCD shows transmitter battery capacity and working frequency
TWM-118G8 - Gooseneck Set
- 8 × gooseneck condenser microphone units in each set
- 420 mm detachable flexible gooseneck, 360° positioning
- Full-metal gooseneck construction for durability
- Same touch mute key, 18650 battery and USB-C charging
- LCD shows transmitter battery capacity and working frequency
Application Scenarios
Flexible, reliable wireless discussion for rooms of every size.
Conference Rooms
Eight units cover the whole table - 200 channels and unique channel IDs let neighboring rooms run their own systems at the same time without interference.
Training Rooms & Lecture Halls
Cardioid condenser capsules and FBX feedback suppression keep the presenter's voice clear at higher volume, while 10–15 h battery life covers full-day sessions.
KeyFeatures
8-Channel Receiver - shared by both models
|
UHF 8-Channel Reception Sixteen-MHz-wide UHF operation (640–690 MHz) with infrared pairing and manual frequency selection. Eight rubber antennas and auto-tracking tuning keep every channel stable, and the standard band can be customized for different countries and regions. |
200 Channels, Multi-System Ready PLL digital frequency synthesis and intelligent circuitry suppress interference. Each channel carries a unique ID, so up to three systems - 3 receivers and 24 transmitters - work simultaneously; handheld and bodypack transmitters share the same 200 channels. |
|
Clear, Faithful Voice A dedicated condenser capsule with proprietary audio processing extends pickup distance and speech intelligibility. Rich mids and highs, wide dynamic range and a natural, full-bodied voice keep every delegate clearly heard. |
Real-Time Status on LCD Two rows of four LCD screens display working channel and frequency, RF and AF signal levels, mute/lock status and each unit's live battery level - with bidirectional battery monitoring for low-battery alerts. |
|
Feedback Suppression & Safe Switching Built-in FBX feedback suppression minimizes howling from room sound reinforcement. A switch-on noise-suppression circuit prevents pop noise from damaging downstream amplifiers and speakers, and a key-lock function prevents accidental changes. |
Rack-Mount & Flexible Outputs The receiver mounts in a standard equipment rack for tidy installation. The rear panel provides 8 balanced outputs plus 1 mixed unbalanced output for easy connection to mixers, amplifiers and DSP devices. |
Options &Customization
Microphone styles- choose the short-rod set (TWM-118Q8) or the gooseneck set (TWM-118G8) per room; both work with the same receiver platform.
- Compatible transmitters- handheld and bodypack transmitters share the same 200-channel platform.
- Frequency customization- the RF band can be customized to comply with the wireless regulations of different countries and regions.
- Multi-system deployment- up to three complete systems (3 receivers, 24 transmitters) operate simultaneously in one venue.
Why ChooseTWM-118
Complete Table Coverage
Eight microphones and eight independent channels in one set - every delegate gets a unit, with one rack receiver to install and manage.
Interference-Free by Design
