AMP-S8 Series+ User Manual P/N 821640 Rev-B

Please refer to Figure-2b and Figure-2c on the following pages to familiarize yourself with the rear panel features of the AMP-S8 Series+

units. The following sections describe the functions of each of the various features found on the rear panels and are referenced, by letter, to

Figure-2b and Figure-2c.

Rear Panel Features

Power Connector

Attach a standard IEC-320 power cord between this connector and mains power.

OPT A - Rotary Switch (2U MDA Model only) or Reset Button (2U SDA Model only)

In the 2U SDA model, this opening features a recessed push-button with a momentary reset function for the SD-SDI input

module. Pressing the button with a small screwdriver or other tool will reset the SD-SDI input functions of the SDA unit.

In the 2U MDA model (but not HDA model) with the CVBS Video Output option installed (Item D), this opening features

a 10-position rotary switch for selecting related functions as shown in the following table:

NOTE: Throughout the manual, the following terms are used to refer to Serial Digital (SDI) signals:

• SD-SDI = refers only to standard SDI (270 Mbps).

• HD-SDI = refers only to high-definition SDI (1.5 Gbps).

• SDI = refers to either standard SDI (SD-SDI, 270 Mbps) or high defintion SDI (HD-SDI, 1.5 Gbps).

Section 2: Operation

OPT B (2U) or OPT (1U) Rotary Switch

The OPT B (2U models) or OPT (1U models) opening features a 10-position rotary switch, which is reserved for future

options and should be left at the factory position 1.

CVBS Video Output (From SDI) Connector (Option for 2U SDA and MDA Models only)

This option is available only on the 2U rack SDA and MDA models.When the CVBS Video Out option is specified, a

female BNC connector installed here outputs CVBS (composite) video encoded from the selected SDI input (Item

E). HD-SDI signals are scaled for proper representation in composite video format. See Item B for how to select the type

of CVBS video output for the MDA model. When this option is installed, a select switch is also installed to allow selection

of the 910213 video scaler module for communication through the RS232 #2 connector (Item G).

This output functions regardless of other selection settings. This feature enables encoding of the SDI signal to CVBS

independent of other monitoring functions (as long as a valid SDI signal is present at the associated input).

SDI Input Connectors - IN1 and IN2 (SDA, HDA, and MDA Models only)

These BNC inputs accept SDI digital audio signals as follows (the DA model does not feature SDI capability):

• AMP-S8SDA = SD-SDI only (Standard, 270 Mbps)

• AMP-S8HDA = HD-SDI only (High-Definition, 1.5 Gbps)

• AMP-S8MDA = HD-SDI or SD-SDI (High-Definition, 1.5 Gbps or Standard, 270 Mbps)

Note that PCM signals embedded within an SDI bitstream are automatically de-embedded for montoring through the unit.

When set to positions 1, 2, 3, or 4, the signals from the CVBS Video Output option (Item D) and the video supplied to

the internal LCD will be the format described for each position in the table (NTSC or PAL) regardless of the input format.

When set to positions 3 or 4, HD-SDI input signals are letterboxed, but SD-SDI input signals are not. Setting the switch to

positions 8 or 9, will force a hardware reset on the video scalar (919213) and audio de-embedder (919212) modules.
