Tascam PA-30 Introduction, Warning To Prevent Fire Or Shock, Hazard, Do Not Expose This

Introduction

The TASCAM PA-30 is a high-performance professional audio power amplifier for nearfield studio monitoring and low-level sound reinforcement. In stereo mode, the PA-30 delivers 30 watts per channel continuously into an 8 ohm load - with no more than 0.05% total harmonic distortion. For applications requiring higher output power, the unit may be operated in BTL (Balanced Transformerless) mode - also known as 'bridged' operation - and will deliver a full 60 watts continuously into 8 ohms (see the 'BTL Operation' section of this manual on page 9). In either mode, it exhibits a flat frequency response characteristic from 20 Hz to 20 kllz (+0, –1dB), with very low residual hum and noise.

For maximum flexibility, the PA-30 is equipped with both XLR-type balanced and RCA-type unbalanced input connectors. These accommodate nominal input signal operating levels of +4 dBm and –10 dBV, respectively essentially eliminating the necessity for external compensating pads or gain stages. A single, continuously variable INPUT LEVEL control attenuates input signals so the unit's sensitivity can be calibrated to the gain structure of the source equipment. The PA-30 is designed and built to provide years of trouble-free service with little or no maintenance. Its well built power transformer easily handles continuous full-power operation, and all power semiconductor circuits are mounted on a large convection-cooled heatsink.

Multiple resettable electronic protection circuits guard against destructive turn-on transients, output overload, DC offsets and output shorts.

While the PA-30 is almost indestructible, it has been engineered to be easy to service. Like all TASCAM professional products, it is backed by a worldwide network of TASCAM dealers and TEAC authorized TASCAM service centers.

Connection and operation of the PA-30 is simple and straightforward. This manual presents a detailed description of the unit's features, along with basic connection instructions and specifications. Please take a few moments to study it before connecting and operating your PA-30 Power Amplifier.
