Biema® - 2 x 500W RMS Amplifier - PA500

Bridgeable “PA Series”. This monster Biema produces a massive 1500W into 8 ohms in Bridge mode, 750W per channel into 4 ohms or 500W per channel into 8 ohms. The massive power capacity together with enhanced engineering and design facilitates ultra service reliability ensuring it is the perfect choice for both hire applications and for permanent installations. It performs tirelessly even in the most demanding applications and is ideal for nightclubs, sporting complexes, cinemas, mobile DJ’s, pub and club PA’s and bands. Engineered with two extra large heatsink tunnels cooled with thermally cued fans which are inoperative at standby or low level inputs. To ensure superior reliability, the amplifier includes a host of protection circuitry permitting operation under the most demanding applications. Features include over-temperature shut down, short circuit protection and output limiting. Each channel includes its own recessed front mounted volume control, rear panel mounted XLR and 6.35mm jack balanced inputs with selectable sensitivity of 0.77V, 1.4V and 3.5V. Enabling input signals from a wide variety of source equipment. Speaker connections are made via heavy duty binding posts or industry standard heavy duty speaker connectors.
