BaseWish CZE-7C 7W 1W FM Transmitter LCD 3.5mm Cable Black

FCC-Certified Dual-Power FM Transmitter

The BaseWish CZE-7C is an FCC-certified FM stereo transmitter offering selectable 1W and 7W output modes. It operates on a 12V DC supply requiring over 2A current load. The unit integrates a BH1415 chip with PLL modulation, audio pre-emphasis, limiter and low-pass filter circuits. Three power amplifiers (two 2SC3355 and one 2SC2053) driven by AT89C2051 and AT24C02 control logic deliver clear stereo sound. An LCD displays the transmission frequency for easy adjustment.

Upgrade from Low-Power Single-Mode Units

This transmitter replaces basic single-power FM modulators that lack FCC certification and adjustable output. The jump is worth it when you need legal compliance for public events such as drive-in services, school functions or light shows. Dual power modes let you match range to venue size while the 50-ohm output impedance and >65dB signal-to-noise ratio maintain audio fidelity. The 100kHz tuning step and ±10ppm frequency stability ensure reliable channel holding.

Suits Event Organisers Needing Certified Range

Ideal for operators running drive-in church, supermarket promotions or fireworks audio who require FCC-certified equipment with selectable power. The 3.5mm audio and mic inputs support external sources. Buyers needing wireless streaming, battery operation or multi-channel switching should look elsewhere. The aluminium chassis provides heat dissipation but the fixed 12V DC input limits portable use without a suitable power source.
