The STCA360-6Z amplifier is a 6-zone 19" rack-mountable commercial amplifier that supports 70V/100V systems and 4–16Ω low-impedance speakers. It delivers 360W total output across six speaker zones with individual volume control for precise multi-zone management. In low-impedance mode, the amplifier operates in direct output without multi-zone distribution. It features Bluetooth audio input, RCA line inputs, Optical (SPDIF) input, 3 mic inputs (including 1 front-panel priority mic input) with echo/tone control, USB playback, and an FM tuner, along with a built-in clipping limiter for protection and stable operation. Audio control and source selection are managed via the integrated LCD display.

STCS6C-PAIR in-ceiling speakers are 2-way units, each featuring a 6.5" woofer and a 1" coaxial compression driver, delivering 60W RMS and 120W program power. Each speaker includes a built-in multi-tap transformer for 70V/100V operation with selectable power taps and 8Ω direct mode for flexible system integration. The in-ceiling design with a white magnetic grille and durable steel backcan allows the speakers to blend seamlessly into ceiling environments, while 120° conical coverage ensures wide and even sound dispersion.

Designed for commercial and residential installations, the STCA360-STCS6C system is suitable for restaurants, retail spaces, schools, offices, warehouses, and other distributed audio environments requiring clear coverage and zone-based control.

Q: What speaker wire should be used for this system?

A: Speaker wire is not included. To ensure optimal performance and minimize signal loss, select the appropriate wire gauge based on the distance between your amplifier and speakers:

Using a thicker (lower gauge) wire for longer runs helps maintain signal strength and overall audio quality.
