Frequently asked questions
Which is better for outdoor paging?
The CSS-H30 is designed for outdoor use, with an IP-65 rating, salt-spray durability, and a 350 Hz high-pass filter to reduce feedback and rumble. The Control 24C is built for interior ceiling mounting and is not rated for outdoor exposure.
Can either handle music playback?
The Control 24C is optimized for background music with phase-coherent, well-integrated tone. The CSS-H30 is a speech-focused paging horn with reduced low-end response and is not ideal for music reinforcement.
What is the impedance difference and why does it matter?
The Control 24C operates at a fixed 16 ohm impedance, standard for commercial audio systems. The CSS-H30 includes a multi-tap transformer with five 70V options (8-ohm direct bypass also available), allowing flexible impedance matching in larger or more complex installations.
Which delivers higher output SPL?
The CSS-H30 produces up to 129 dB peak SPL and 108 dB sensitivity, making it far more powerful. The Control 24C is engineered for low-to-moderate SPL environments and is not suitable for high-output applications.
