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).
The earth pin on the IEC mains inlet connector is connected to the metal frame of the
equipment, to 0 volts on the internal DC PSU and to signal ground, unless otherwise
stated. All metal panels are bonded together.
In all cases, the frame of the equipment must be earthed on installation.
Due consideration for cooling requirements must be given when mounting the equipment.
Ideally 1RU of rack space should be left above and below the unit.
Check that the fuse rating is correct for the local power (mains) supply. Replacement
fuses must be of the same rating and type for continued protection against fire risk.
Do not switch on until all connections are made.
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.

AMU2-8HD+/3G AUDIO MONITORING UNIT
1.0 Introduction
This handbook covers the AMU2-8HD+ and AMU2-8HD-3G Audio Monitoring Units.
The AMU2-8HD+/3G are full rack 2RU x 310mm deep Audio Monitoring Units with eight
TSL 53 segment bargraphs.
The following features are standard:
•Four AES/EBU inputs.
•Two HD/SDV auto sensing inputs.
•Re clocked output of input.
•Two Stereo analogue inputs.
•Phase reverse switch.
•Out-of-phase error indication.
•Down converted video or SDV output
•Additive output switch selection.
•Composite output.
•Headphone outputs with LS muting.
•Fixed and variable stereo line outputs of selected pair.
•Four simultaneous line outputs.
•Dolby compatible D and E.
•Metadata display.
•EBU digital, UK PPM and EBU PPM scales available.
•Internal amplifier.
•1080p50 / 1080p/60 capable (3G units only)

2.0 Front Panel Controls
2.1 Input and Meter Selection Buttons
AES1, 2, 3 & 4 AES input. This is selected by first pressing the AES select
button, then selecting A(1/2),B(3/4), C(5/6), D(7/8) respectively
on the LS monitoring panel.
Analogue 1 & 2 These inputs are selected by pressing the Phase
Reverse/function button and then the AES/ANLG button on the
input select panel. The signals are displayed on bargraph A
(1/2) and B (3/4).
S/HD (Auto sensing) This is selected by pressing the S/HD button 1 or 2 and then
selecting GP1 to GP4. The de-embedded SDV or HD is then
displayed on the bargraphs A(1/2),B(3/4), C(5/6), D(7/8)
respectively. Selecting e.g. group 1 and 2 together allows all
eight channels to be monitored.
Dolby Encoded Dolby can either be carried on an AES bit stream or
as embedded HD or SD. To select the Dolby function press the
DOLBY button after selecting either AES or S/HD buttons. If a
valid Dolby signal is present the Dolby button will illuminate
steady red. If a Dolby signal is not present or is lost the button
will flash. To select one pair from one group containing two
Dolby signals on each pair, select the group (1, 2, 3 or 4) from
the H/SDV input and then either A, B, C, or D from the input
selector to choose the pair.
Letterbox Shows the composite output as 16:9 aspect ratio on a 4:3
monitor.
Ø Rev (Function) Momentary phase reverse between A1 and A2 outputs.
Brightness To increase the brightness of the bargraph display
Press phase reverse and monitoring select A. To
decrease the Brightness press phase reverse and
monitoring select B.
Reference Marker To turn the reference marker on and off press phase
Reverse and the CUT button.

Meta Data Display This window indicates:
Channel coding (Rate/non PCM/Dolby D/Dolby)
Channel format (e.g. 8x1/2+2+2+2 etc)
Digital peak read out of selected pair.
Dialogue normalisation value where set
N.B. To reset/refresh display press Phase Reverse then Dolby select
switches simultaneously.
2.2 Output Switching and monitoring
A, B, C & D These buttons select the audio from pairs 1/2 (A) through to 7/8
(D)
The buttons toggle. Additive mixing is possible if two or more
buttons are selected together and are fed only to the variable
line outputs.
ALL Enables multi-channel listening on variable outputs. When
selected, multichannel variable outputs are enabled and full
surround can be monitored.
Selecting ALL, holding down and pressing output selection A
or B will toggle between using ABC for discrete 5.1 or BCD for
discrete 5.1.
LEnables the left hand channel to be monitored by both outputs.
R Enables the right hand channel to be monitored by both
outputs.
M A mono signal of the left and right hand channels is applied to
both outputs.
Lt Rt Allows a multi channel signal to be monitored and is a stereo
‘down mix ‘of a Dolby decoded signal. (Mutes multi channel
outputs)
5.1 Enables/Disables 5.1 metadata dynamic range control.
Dim Approximately 16dB of attenuation is switched into the audio
path.
Cut/Mute The front panel button Cut(s) the signal to all Variable O/Ps.
Volume The loudspeaker, headphone and variable O/P’s may be
varied.

6.0 Notes
0 dBm = 0.775V into 600Ωi.e. 1mW power dissipation.
0 dBu = 0.775V rms = PPM 4.
Nominally, -18 dB ref 0FS = 0 dBu output.
European line up: -18 dBu
American lineup: -20 dBu
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 Dolby (CAT552) card can be reset by pressing the phase reverse and the
Dolby select buttons simultaneously.
The screw locks on the D25 connectors use UNC 4-40 standard threads.
6.1 One frame Delay in Dolby mode option.
This operates on the down converted output only.
