INTRODUCTION
Thank you for purchasing the Tannoy System 800A Active Monitor.
The System 800A is a compact, active near-field reference monitor. Using an advanced
Dual Concentric 8” 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 800A are packed in pairs. To remove the speakers from 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 that 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 800A makes it
particularly easy to install.
After having unpacked the unit, first check that the operating voltage is correctly set
(rear panel, location 1 in figure 1), 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.
