Introduction, Unpacking and visual checks

INTRODUCTION

Thank you for purchasing the Tannoy System 600A Active Monitor.

The System 600A is a very compact, active near-field reference monitor. Using an advanced Dual Concentric 6.5” driver, it offers the advantages of point source operation in a cost-effective design, combined with the benefits of active speaker technology: a highly optimised active crossover section; ideal matching between amplifiers and transducers; higher output for lower distortion. Active user controls are also provided to allow further bass extension (LF contour) and greater flexibility. The attractive octagonal shape of the cabinet, with its original rounded edge front panel also contributes to the excellent acoustic performance of the system.

Designed to be located on top of the mixing console, in a landscape format, it will equally suit other situations where it can be used in portrait mode without any drawback, thanks to its point source operation.

This manual is intended to provide the user with some useful advice on how to install and use the loudspeakers, as well as more technical information about how the system is designed, and its detailed specifications. Our goal is to help you get the best results from this monitoring system.

OPERATING INSTRUCTIONS

Unpacking and visual checks

The System 600A are packed in pairs. To get the speakers out of the carton without damage open the end flaps fully and bend them right back . Remove the upper cushion, then lift each loudspeaker out carefully.

Inspect the speakers for signs of transit damage. In the unlikely event of this having occurred inform the carrier and the supplier. Keep all the packaging if damage has occurred as this will show evidence of any excessive handling forces. It is also a good idea to keep the carton for future transportation.

Preliminary recommendation

Initially we would like to give you a word of warning about the high sound pressure levels which these speakers are capable of generating. Over a sustained period of time levels over 95 dB for 8 hours per day will eventually cause permanent hearing loss. Because Tannoy monitors have very low levels of time, amplitude and frequency distortion it is not always obvious that the sound pressure level is high whilst working with them.

For continuous exposure we recommend the occasional use of a sound level meter capable of integrating the sound level over a period of exposure according to noise control standards. This should be used just to check that noise levels are always within safe limits.

Installing and connecting the system.

The compact, integrated design of a self-powered unit like the System 600A makes it particularly easy to install.

After having unpacked the unit, first check that the operating voltage is properly set (rear panel, location 1 in figure 1), and if it is not adjust the selector to the appropriate position. Also check and if necessary replace the fuse (location 3), as its rating should match the operating voltage.

When choosing a suitable location for the monitors, bear in mind that the physical mounting of loudspeakers can have a large influence on performance. For best results
