We have written this manual with the aim of helping installers, sound engineers and consultants alike get to
grips with the 

TCS-80X 

series and obtain its maximum capability.

If you are new to BSS equipment, we recommend that you begin at the start of the manual. If, however, you
are already familiar with the intended application, and just want to get the unit installed without delay, then
follow the highlighted sections.
Since this manual is dual purpose in covering both the 

TCS-803

 and the 

TCS-804

 units, information that applies

to only one of the units will be clearly noted for you. Where a particular function applies to both units, the
method of access and operation is identical for both units and the manual will show pictures of the 

TCS-804

 as

an example.
Should you have any comments or questions about applying the 

TCS-80X

 series within your application, please

write to us, or e-mail us, at the addresses in the warranty section.
We welcome any comments or questions regarding the

TCS-80X

 series or other BSS products, and you may

contact us at the address or World Wide Web site given in the warranty section.

This equipment has been tested and found to comply with the following European Standards for
Electromagnetic Compatibility:

Emission Specification:

EN55013

(1990)

(Associated equipment)

Immunity Specification:

EN50082/1

(1992)

(RF Immunity, Fast Transients and ESD)

Mains Disturbance:

EN61000/3/2

(1995)

For continued compliance ensure that all input and output cables are wired with cable screen connected to Pin
1 of the XLR. The input XLR Pin 1 on BSS equipment is generally connected to chassis via a capacitor to
prevent ground loops whilst ensuring good EMC compatibility.
