Power amplifier for column speaker array in auditorium?

For a column speaker array in an auditorium, VISSONIC's Class D amplifiers provide clean, efficient power with models available in 2-channel and 4-channel configurations.

Recommended amplifier models:

VIS-AMD4300 — 2 x 350W Class D Amplifier — ideal for driving a pair of column speakers (left/right) or two zones. Class D topology means high efficiency (>90%), low heat, and compact 1U rack form factor.

VIS-AMD4300 — 4 x 350W Class D Amplifier — perfect for 4-zone auditorium setups or larger column speaker arrays where you need independent control per zone.

Column speaker lineup for auditoriums:

VIS-CS23 — 2x3" Column Speaker — for smaller zones or fill speakers

VIS-CS43 — 4x3" Column Speaker — the workhorse for medium auditoriums, good vertical directivity

VIS-CS83 — 8x3" Column Speaker — for large auditoriums, highest SPL and narrowest vertical beam for long-throw applications

System design checklist:

Match amplifier power to speaker power handling — the 350W/channel from VIS-AMD4300/4350 comfortably drives any of the column speakers with headroom

Check impedance — VISSONIC column speakers are typically 8 ohms. The amplifier delivers 350W at 8 ohms per channel

For distributed systems with many speakers, use 70V/100V constant-voltage mode if the speakers support it, or dedicate one amplifier channel per zone

Feed the amplifier from a dB-NET Digital DSP Audio Matrix for EQ, delay alignment between columns, and zone level control

Add a VIS-SUB12 12-inch Subwoofer with its own amplifier channel for low-frequency reinforcement in larger auditoriums
