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.
the monitors should be mounted on a rigid structure, preferably with the use of soft pads (rubber, Sorbothane, Blu-Tak etc..). When used in the landscape orientation, we recommend location of the monitors so that the drive units are toed inwards, with their axes oriented towards the listening position. The distance between the two speakers should be about 1.5 to 2 metres, depending on the monitoring position.
If the source itself has a balanced output, use shielded twin conductor cable (microphone cable) connecting pin 2/T to pin 2/T, pin 3/R to pin 3/R, and pin 1/S to pin 1/S (using the shield). If the source has an unbalanced output, a single conductor shielded cable can be used, connecting pin 2/T of the input to the “hot” signal pin of the source, while pin 3/R and pin 1/S should be linked together and connected to the source signal ground.

SYSTEM DESCRIPTION AND PHILOSOPHY A loudspeaker design naturally splits into various parts: cabinet, lower frequency, higher frequency, and crossover which, for the System 600A, is integrated in the amplifier assembly. The design of these parts cannot take place in isolation, as they are all interdependent. The integration of all the features described below is what makes the whole loudspeaker system even greater than the sum of its individual parts. Drive unit.
attention paid regarding the sculptured front panel to provide smooth, rounded edges which minimise side diffractions. Another problem involved in cabinet design is to ensure that the box will effectively behave as neutrally as possible, ideally without interfering at all with the sound field emitted by the drive unit and the port. There are two main ways the box can get into vibration. First there can be a mechanical transfer of energy between the drive unit and the cabinet front panel.
SERVICING Cabinet finish. To remove marks and scuffs, use a medium soft brush. If necessary, a little warm water and detergent can be used, but under no circumstances use a solvent or abrasive cleaner. The surface will change colour when wet but will return to normal when dry. For touch-up of paint chips contact your local Tannoy service agent for materials and guidance. Dual Concentric driver removal. Before any servicing operation the amplifier should be disconnected from signal input and mains power.
Amplifier. A fuse is located just under the mains input (location 3 in figure 1). Replacement is simple and a spare fuse is provided inside the fuse housing itself. Always use the correctly rated fuse, as indicated on the silk screen printing, there are two different types according to the operating voltage. Any other servicing regarding the electronic section should be undertaken by qualified and authorised personnel only.
