EXTERNAL REMOTE LINE SELECTOR
(EXT. RLS)
The Ext. RLS (PRE99-947) is a rack-mount ste-
reo source selector with 16 balanced inputs and a
single balanced output that connects to any Telco
or RLS module. It works with both balanced ana-
log and AES/EBU digital signals, however, each
Ext. RLS can only route analog or digital audio,
not both. To route both analog and digital audio,
two External RLSes are required to provide up to
32 source selection—sixteen analog and sixteen
digital, to a single module.
The External RLS’s rear view, connector pinout
and typical wiring diagrams are shown below.
External RLS and BMX
digital
Modules
RLS or Telco modules can be set as a control
module for an External RLS. Once a module is
configured to control an Ext. RLS (see below), the
source can be dialed up and taken using the
module’s Source Selector and Take button.
To configure an RLS or Telco module for use
with an External RLS, set their DIP switches as
follows:
