Tannoy IWSA500
Power Amplifier, One Channel, 500W into 4 ohms

IWSA500

The iwSA 500 is a single channel BASH© power amplifier specifically designed to deliver 500 watts (max) of optimally matched power to the Tannoy iw62 TS in-wall subwoofer.

By augmenting the low frequency output of a full range installation, with a continuous power handling of 200W RMS, the iw62 TS subwoofer is capable of delivering impressive results in large domestic installations, and well as commercial applications such as small venues, restaurants, bars, public buildings and business music systems.

The subwoofer unit is unique in that it can operate in either passive or active mode, selectable by a switch on the baffle, and mono or stereo mode, by means of link wires on the circuit board. In active mode, the use of an external controller allows low frequency extension and equalization to be applied, and the crossover point to be tailored to the rest of the system and room.

With front mounted control of level, phase and a continuously variable crossover, adjustable from 50Hz – 150Hz, the iwSA 500 amplifier will therefore offer all the control needed to optimise the integration of this subwoofer system with the mid / high units, regardless of the installation positions.

Audio input is via 2 x unbalanced RCA’s, outputs are 4 x gold plated binding posts, while other controls include crossover bypass switch, limiter function switch for one or two sub configurations and sleep mode defeat switch.

The 2U iwSA 500 casing mounts directly into a standard EIA 19” rack or the brackets can be removed for shelf location with no ventilation issues.
