Ceiling speaker system BIAMP CM4T Apart
APart CM4T is a small ceiling speaker with a 4" full-range speaker. The speaker has a double cone and is impregnated with a special material for higher quality reproduction and protection from moisture. APart CM4T is slightly larger in size than a recessed light, but has clear and powerful sound. APart CM4T is ideal for use in cases where a small ceiling speaker with expressive sound is needed. Speaker frame - metal. APart CM4T can connect to both 100-volt and low-impedance audio amplifiers. When connected to a 100-volt line, you can use one of three volume levels (6 - 3 - 1.5 W). In 100-volt mode, all speakers are connected in parallel, and the number of speakers is limited only by the 100-volt amplifier and speaker power: the total power of all speakers must not exceed the power of the amplifier. The speaker features an IMC protection system to prevent overloading your amplifier. When using APart CM4T as a low-impedance loudspeaker, you need to connect it bypassing the transformer, directly to the speaker. All necessary terminal blocks are attached to the speaker housing. The speaker impedance with this connection will be 16 Ohms, this allows you to connect in parallel up to 4 speakers per channel to an amplifier with a minimum possible load of 4 Ohms and 2 - 3 speakers per channel to an amplifier with a minimum possible load of 6 Ohms.
