Frequently asked questions
When would I need 125W instead of 75W per channel?
The 125W CT8150 is essential for larger venues, long-throw distributed systems, or setups with multiple zones that demand higher headroom to maintain clean gain structure and prevent digital limiting. The 75W CT875 suits smaller venues, classrooms, and meeting spaces where modest SPL requirements exist.
What is the weight and cooling difference?
The CT875 weighs 10 lb with an idle power draw of 23.0W, making it lighter and more power-efficient than the CT8150. Both use convection cooling and produce zero fan noise, but the CT875's lower thermal load is advantageous in confined spaces like ceiling plenum installations.
Are the audio specs identical?
Both amplifiers achieve over 90% efficiency via DriveCore™ technology, deliver THD and intermodulation distortion under 0.05%, and maintain stable operation across 2–16 ohm impedances. The CT8150 adds a 110 dB signal-to-noise ratio specification and ±0.5 dB frequency response detail, reflecting its higher-power design focus.
Which is better for installed sound?
Both are purpose-built for installed sound. The CT8150 suits larger properties and multi-zone systems; the CT875 is ideal for smaller or retrofit installations where weight, space, and power efficiency are constraints.
