TCS 80X
User Manual

V3.0 JMK 31October1996
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.

1.0 The TCS-80X Series.
The TCS-803 and TCS-804 form a series of multitap time correction units that
offer you the very best from todays' affordable digital technology. Utilising
advanced BSS proprietary conversion techniques they have exceptional
headroom, phase linearity and low level resolution that will not weaken a
conventional high quality analogue signal processing chain. Whether your
application is professional live sound, theatre sound, broadcast or disc
mastering the TCS-80X series will offer the most cost effective and intelligent
high specification multitap time delay that is available.

BSS Delays
2.0 What is special about BSS Delays?
Some of the features available within the series are:
• Stereo operation with two outputs per channel accurately linked, or dual
monoone-in/two-out.
• Mono one-in/four-out on the TCS-804. Mono one-in/three-out on the TCS-
803.
• Friendly rotary control knob for all parameter adjustments.
• Time or distance entry and display in milliseconds, feet, inches or metres.
• 10uS minimum delay steps.
• 105dB usable dynamic range includes full +20dBu headroom with fine
resolution at low signal levels. No companding or pre-emphasis means
superior high frequency performance.
• Exceptional phase linearity and HF accuracy from high sample rate and
gentle filtering.
• 12 non-volatile user programmable memories with remote recall via contact
closure or Midi.
• Maximum delay up to 2.6 seconds on TCS-804 in mono mode up to 1.3
secondsonTCS-803.
• Master/slave linking of multiple units by Midi.
• Delay time compensation for auditorium ambient temperature change. Fully
automatic on the TCS-804 with optional probe fitted.
• Electronic security lockout with optional mechanical security cover.
• Relay controlled signal bypass optionally available which is also linked into
fail-safe processor and power supply watchdog.
• Digital level control for both input headroom and output gain on the TCS-
804, gives automatic headroom compensation and allows remote control of
output levels and program storage.
Every TCS-80X is manufactured to the highest professional standards with a
robust steel case, high quality circuit boards and ICs, and high quality
components to provide reliable performance under the most demanding
conditions of the global sound-reinforcement environment. In common with
all other BSS equipment, the TCS-80X is subject to stringent quality control
procedures throughout the manufacturing process. Components are tested
against demanding acceptance criteria. Every completed unit is tested both
by measurement and in a listening test carried out by trained audio
professionals. To positively ensure reliability, all units are burnt-in for fifty
hours, before being tested.

3.0 Earthing Requirements
WARNING! THIS APPLIANCE MUST BE EARTHED.
IMPORTANT: The wires in the mains lead are colour coded in accordance
with the following code.
!The wire which is coloured Green and Yellow or Green must be connected
to the terminal which is marked with the letter ‘E’ or by the Earth signal
or which is coloured Green and Yellow or Green.
"The wire which is coloured Blue must be connected to the terminal la-
belled ‘N’ or coloured Black or Blue.
#The wire which is coloured Brown must be connected to the terminal
labelled ‘L’ or coloured Red or Brown.
Those units supplied to the North American market will have an integral
moulded 3 pin connector which is provided to satisfy required local standards.
The mains voltage selector switch provides a simple external adjustment to
allow operation on all international AC power standards. The allowable ranges
for the supply voltage are:
90VAC up to 132VAC on the 120V position and
180VAC up to 264VAC on the 240V position.
Outside of these ranges the unit will not work satisfactorily, if at all. Voltages
in excess of the maximum will probably cause damage. Voltages below the
minimum will cause the power supplies to drop out of regulation, degrading
the performance of the system.
As part of BSS' system of quality control, this product is carefully inspected
before packing to ensure flawless appearance.
After unpacking the unit, please inspect for any physical damage and retain
the shipping carton and ALL relevant packing materials for use should the unit
need returning.
In the event that damage has occurred, please notify your dealer
immediately, so that a written claim to cover the damages can be initiated.
See Section 22.
