Amplifiers
1.1 Introduction
The HDA-1941/3941 is a 3G/HD/SD SDI video DA which supports a variety of compressed and uncompressed serial
digital video signals. The HDA-1941/3941 provides up to nine reclocked outputs with automatic input equalization for
up to 200 meters (656 feet) of cable using Belden 1694A at 1.5 Gb/s and up to 100 meters (328 feet) at 3 Gb/s.
The HDA-1951/3951 is a dual 3G/HD/SD SDI video DA, which supports a variety of compressed and uncompressed
serial digital video signals. The HDA-1951/3951 provides up to ten reclocked outputs (dual 1x5) with automatic input
equalization for up to 200 meters (656 feet) of cable using Belden 1694A at 1.5 Gb/s and up to 100 meters (328 feet)
at 3 Gb/s.
Critical applications protection is provided by bypass relays available on selected rears.
Note: HDA-1941 and HDA-1951 are Densité-2 series cards. HDA-3941 and HDA-3951 are Densité-3 series cards.
Apart from the size difference, they are functionally identical.
Function Densité 2 Densité 3
Single DA HDA-1941 HDA-3941 These two cards are functionally identical.
Dual DA HDA-1951 HDA-3951 These two cards are functionally identical
Note on terminology – to simplify the terminology in this document, the term “HDA” will be used to describe features
that apply to all four products. Specific product names will be used in all other cases.
1.2 Features

2 Installation
2.1 Installing the Rear Connector Panels
Grass Valley Densité-series cards are each associated with a rear connector panel, which must be installed in the
Densité frame before the card can be inserted.
Rear panels for HDA-1941/3941:
Rear panel Densité Connectors Slots Outputs Bypass

HDA-395N-3SRP 3 BNC 1 2 x 3
HDA-395N-3SRP-R 3 BNC 1 2 x 3 2
HDA-395N-3SRP-D 3 DIN 1 2 x 5
.
All cards and rear panels can be installed with the frame power on. The card has connectors which plug into a mid-
frame mother board for distribution of power and for connection to the controller card, and a second connector which
plugs directly into the rear connector panel for input and output.
The rear connector panel must be installed with the card out of the frame.
To install the connector panel:
1. If a card is installed in the slot whose rear panel is being changed, remove it by tilting up the swivel handle on
the front of the card to lever the connectors apart, then using the handle to pull the card straight out of the slot.
2. Remove the existing panel (either blank or belonging to an existing card that is being changed) by releasing the
captive screw(s) at the bottom.
3. Position the new panel and secure it in place with the captive screw(s) at the bottom.
2.2 Installing the HDA Card
Once a matching rear connector panel has been installed, install the HDA card as follows:

GUIDE TO INSTALLATION AND OPERATION
HDA-1941/51 & HDA-3941/51 | 5
1. Open the front door of the frame.
2. Slide the HDA card into the slot and push gently on the swivel handle to seat the connectors.
If the card is used with a double-width rear panel, it should be inserted into the right-hand slot. Inserting the card
into the wrong slot will not damage the card, and will be flagged by the on-card status LED flashing red to
indicate that there is no connection to the rear panel.
3. Close the front door of the frame.
2.3 Rear Connector Panels
The following diagrams illustrate the layout and connectors on the HDA-1941, -1951, -3941 and -3951 rear panels.
