AMS82 8 CHANNEL AUDIO MONITORING SYSTEM by Ward­Beck Systems Rev:Oct.01 2014
AMS82 ​
(version 2.1.1.8 and above) Carefully unpack your AMS82 and make sure that damage has not occurred during shipping. The unit should be ready for use as soon as it is plugged in to the AC power source and a signal is connected to it. Please note: The default MODE setting for a unit that includes a Dolby Decoder is MODE 1 in this mode inputs may be a mix of Dolby E, Dolby AC­3 or PCM and it is recommended that the unit be operated in this mode only. The default mode for units without a Dolby Decoder is MODE 2. In this mode inputs can only be PCM and the unit should only be operated in this mode. MODE 4 is a task specific application that may be used when the unit is equipped with a Dolby Decoder. Please refer to the set up for MODE 4 in this manual. An optional DEMUXER may be installed in your AMS8. This increases the input capability of your unit. The DEMUXER is capable of extracting all embedded groups ( a maximum of eight AES signal pairs) from the two digital video signals. FRONT PANEL DISPLAYS AND CONTROLS Please note that primary functions for controls are designated in white, while secondary functions are designated in green. FRONT PANEL DISPLAYS Eight 46 segment LED bargraph meters display VU and Peak Program information simultaneously. A reference LED (red) at the zero mark is continuously illuminated. Three eight­character dot­matrix displays display signal parameters and status information. During setup, these displays are used to guide the user in making selections. FRONT PANEL CONTROLS There are eight illuminated push button switches arranged in two rows of four. The upper row designated INPUTS selects the input source to be monitored. The lower row designated PRESETS selects a preset configuration or condition under which the signal is monitored. The two control knobs designated SELECT and VOLUME are rotary shaft encoders with integral push switches. In the simplest mode of operation, the SELECT knob allows the user to scroll through available options while the VOLUME button adjusts the listening level of the AMS8's speakers. All eight pushbuttons, as well as the two knobs with integral push switches, are used in conjunction with the three eight­segment readouts when the unit is configured during SYSTEM SETUP.

can also be selected. To select a preset mix, press any one of the four PRESETS buttons A, B, C or D. (In Version 1.x.x.x. and above) Select SDI 1/2 for SDI Groups 1 and 2 Select SDI 3/4 for SDI Groups 3 and 4 (In Version 06VA0001 and above) Select SDI 1/2 for SDI 1 (A) Groups 1 and 2 Select SDI 3/4 for SDI 1 (A) Groups 3 and 4 Select SDI 5/6 for SDI 2 (B) Groups 1 and 2 Select SDI 7/8 for SDI 2 (B) Groups 3 and 4 OPERATING IN MODE 4* The AMS8 would be set to operate in Mode 4 for a task specific application. In Mode 4, the types of signals that can be connected to the input source connectors are strictly defined. Inputs 1, 2 and 3 must be PCM and input 4 must be a multi­channel Dolby signal. As in other modes, to toggle between the unbalanced and balanced sources, push and turn the SELECT knob. Inputs1, 2 and 3 are simultaneously selected and the INPUTS pushbuttons 1/2, 3/4 and 5/6 will be illuminated. The levels of the three sources will be displayed on the LED bargraph meters CH1 through 6, and the top left and right readout will display ​
PCM Stereo​
. When the 7/8 button is pressed, the multi­channel audio levels will be displayed on CH 1 through 8 meters as appropriate, and the readout will indicate the type of signal that is present 5.1, 5.1 +2, etc. Please refer to the ​
DATA TABLE ​
in this manual for the types of Dolby E and AC­3 signal formats. Under normal conditions, with no PRESETS button pressed and the multi­channel source selected, the speakers will be fed with a Left and Right overall mix (​
LoRo​
). To listen to specific channels in solo, paired or mix mode, please refer to the operation as described under Mode 1 in this manual. VIEWING THE METADATA OF A MULTI­CHANNEL SIGNAL The AMS8 is capable of displaying metadata information that has been embedded in the multi­channel signal stream. It can display the method of encoding used (please refer to the ​
DATA TABLE in this manual). It can also display the Dialogue Normalization (Dial Norm) values that are available. To read this data, rotate the SELECT knob one step at a time. For example, a ​
5.1 + 2 signal is selected for monitoring. The Dial Norm values displayed are ​
Dn1 ­27​
, ​
Dn2 ­31 where ​
Dn1 refers to the Dial Norm for the 5.1 signal and ​
Dn2​
refers to the +2 portion of the signal. Mix levels ​
(Mx 1​
, ​
Mx 2​
, etc.) are available only on Dolby AC­3 signals. If a value does not exist, the readout will display ​
NAN​
for the term Not A Number. The frame rate (​
Fr​
) is available on Dolby E signals only, eg Fr 29.97. Lastly is the Data Rate (​
Dr​
) which is only available on Dolby AC­3 signals. For other signals, the readout will display ​
NAN​
.​
​
If the audio is PCM, there will not be any metadata. THE VOLUME CONTROL In mode 4, the speaker audio and the rear panel AES outputs have independent volume controls. The primary function of the VOLUME control is to adjust the listening levels of the speakers. If the unit is not in the system setup mode, as soon as the control is touched it will revert to its primary function. The gain/attenuation, in dB that is applied to the signal being listened to, will be displayed by the readout. Rotating the knob clockwise increases the listening level. Rotating it counterclockwise lowers the listening level. To control the level from the rear panel AES outputs, push the knob once. An (​
X​
) will display along with the current gain/attenuation, in dB.
