SAFETY
Installation.
Unless otherwise stated TSL equipment may be installed at any angle or position within an
operating temperature range of 5° - 30°C.
All TSL equipment conforms to the EC Low Voltage Directive:
EC Low Voltage Directive (73/23/EEC)(OJ L76 26.3.73)(LVD).
Amendment: (93/68/EEC) (OJ L220 30.8.93).
In all cases the chassis of the equipment must be earthed on installation.
The external power supply provided with this product may be one of two types:
1. A Class 2 double insulated type with a ‘figure of eight’ mains input connector.
2. A Class or Level 3 type with an IEC mains input connector. This type offers a functional
earth and NOT A SAFETY EARTH via the earth pin of the IEC mains input connector to
the outer of the of the co axial power connector.
All metal panels are bonded together.
Check that the voltage selector setting (if fitted) and the fuse rating is correct for the local mains
supply.
Due consideration for cooling requirements must be given when mounting the equipment. It is
recommended that a 1RU of rack space, or a vent panel, should be left above and below the unit.
This unit requires rear support.
WARRANTY, MAINTENANCE AND REPAIR
All TSL equipment is guaranteed for one year from the date of delivery to the customer’s premises.
If the equipment is to be stored for a significant period, please contact TSL concerning a possible
extended warranty period.
Failure during warranty
If any TSL product should fail or become faulty within the warranty period, first please check the
PSU fuses.
All maintenance work must be carried out by trained and competent personnel.
If equipment has to be returned to TSL for repair or re-alignment, please observe the following
overleaf:

TSL Returns Procedure
Please telephone +44 (0)1628 564610 and ask for Support who will provide a Returns Number.
This will enable us to track the unit effectively and will provide some information prior to the unit
arriving. Please do NOT return faulty equipment without first obtaining a returns number as this is
likely to result in a delay in the repair of the equipment.
For each item, this unique Returns Number must be included with the Fault Report sent with the
unit.
A contact name and telephone number are also required with the Fault Report sent with the unit.
Fault report details required.

Packing
Please ensure that the unit is well packed as all mechanical damage is chargeable. TSL
recommends that you insure your equipment for transit damage.
The original packaging, when available, should always be used when returning equipment..
If returned equipment is received in a damaged condition, the damage should be reported
both to TSL and the carrier immediately.

Monitoring selection Switch (Including DOLBY indicator/switch)
This switch has two functions. When the unit is receiving a Dolby
signal, which can be carried on an AES or SD/HD embedded
audio data stream, the DOLBY indicator will show green and the
outer green characters on this switch will apply. These are as
follows: Lt Rt, Left Right, C LFE, and Ls Rs. (Left total, Right
Total, Centre, Low Frequency Effects and Left Surround, Right
Surround.) Theses stems are monitored in pairs.
When a DOLBY signal is NOT present the DOLBY presence
indicator changes colour to amber and the inner white text
applies. Under these conditions the following can be monitored,
Stereo, Left, Right and Mono. N.B. Position D is spare.
With the output selector in the Lt Rt /stereo position:
Pressing the Dolby button will enable/disable the decoded 6/8
channel line outputs as follows;
Disabled (default): First pair only active with Lt Rt, other pairs
muted.
Enabled: Full 5.1 or 7.1 decoding.

The level configuration switches on the HDC2 board operates in a “2’s complement” manner the
relationship between the dBfs level setting in the digital domain and the dBm level setting in the
analogue domain. The “zero” position with all switches in the down position is designed to give
0dBm out for a level of -18dBfs in digital space. See below for configuration

Notes
There are no user adjustable assemblies/components within this unit.
This unit requires rear support when rack mounted.
In order to affect status changes of the unit using the rear DIP switch, the unit will require re
powering before the changes take effect.
Output analogue levels are adjustable over the following range:
0dBm = 0.775V into 600Ω
i.e. 1mW power dissipation.
0dBu = 0.775V RMS = PPM 4.
Nominally, -18 dB ref 0FS =
0dBu output.
European line up :
-18 dBu
American line:
-20 dBu

General Notes
Please note that some American equipment has the function of the XLR pins 2 & 3 reversed.
TSL product is wired to the European standard
The screw locks on the D25 connectors use UNC 4-40 standard threads.
