The 250BL delivers 2 × 50 W at 4 Ω, or 2 × 25 W at 8 Ω. The BL suffix marks low impedance: this amplifier drives wired speakers directly, not a 100 V line. The two outputs work as separate zones, each with its own level control.
A mic/line input on the front panel puts an announcement microphone within reach—no need to reach behind the rack. Rear connections add two line inputs A and B, plus a paging input, to complete the routing.
The chassis occupies half a rack width in 1U—21.4 cm wide, 4.4 cm tall, 31 cm deep, weighing 2 kg. Two units fit side by side in a single U, or mount the unit under a counter using the optional bracket kit.
Opti-Voice lowers the music when a page arrives, then returns it to level. The trigger threshold adjusts from the front panel, preventing unwanted cuts when the background is busy.
