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 frame of the equipment must be earthed on installation.

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.

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-MK3 5 ISSUE 1

2.1 Input and Meter Selection Buttons

Analogue 1, 2, 3 & 4

Analogue inputs. These are monitored simultaneously by pressing the ANALOGUE input select button, and displayed on the bargraphs, A(1/2), B(3/4), C(5/6),

D(7/8) respectively.

AES1, 2, 3 & 4

AES inputs. These are 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. NB:

These switches do not illuminate when selected as these sources are automatically displayed on the bargraphs when a signal is present. The level can also be read in the LCD display.

S/HD (Auto sensing)

This is selected by pressing the S/HD button 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 group 1 and 2 together allows all eight channels to be monitored.

Dolby (Auto sensing)

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 chose pair.

Letterbox

Shows the composite output as 16:9 aspect ratio on a

4:3 monitor. Operates on HD source only.

Ø Rev (Function)

Momentary phase reverse between A1 and A2 on variable and fixed line also on the loudspeaker output.

Brightness

Reference Marker

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.

To turn the reverence marker on and off press phase

Reverse and the CUT button.

Meta Data Display

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 fixed and variable line outputs.

ALL

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 Dolby and Phase

Reverse select switches simultaneously.

Enables a raw post Dolby multi channel signal to be monitored on the fixed line outputs. (Outputs not muted.)

L Enables the left hand channel to be monitored by both outputs. (Outputs muted)

R

Enables the right hand channel to be monitored by both outputs. (Outputs muted)

M

A mono signal of the left and right hand channels is applied to both outputs. (Outputs muted)

Lt Rt

Allows a multi channel signal to be monitored and is a stereo ‘down mix ‘of a Dolby decoded signal. (Mutes multi channel fixed outputs)

5.1

Enables a Dolby digital emulation to be monitored on the fixed line outputs. (Outputs not muted.)

Dim

Approximately 16dB of attenuation is switched into the audio path.

Cut/Mute

The front panel button Cut(s) the signal to all O/Ps.

Variable Line O/Ps are possible via a rear connector. A ground is required on the appropriate pin to activate the

MUTE condition.

AMU2-8HD-MK3 7 ISSUE 1

Volume The Headphones O/P and the Variable Line O/P may be varied. (N.B. This control also acts on the main line outputs if the option has been selected on the AMU2-

This input auto detects HD or SDV signals.

This connector gives a re clocked output of the input signal.

3.8 Down converted output connector (Option)

This gives a down converted SD output of HD (Vision only). This also gives

A re clocked output if SD is used on the input.

3.9 Composite output connector

This gives a composite output of the S/HD input.

4.0 LS Output

This is a single ended amplifier therefore one side may be connected to ground.

This option is available but will be set to ‘fixed’ unless the option for

‘variable’ is checked on the specification sheet at the time of ordering.

Please contact [email protected]
