Allied SX-190, Instruction Manual

SECTION 1: INSTALLATION 
 
 
1.1 UNPACKING 
 
Immediately after receipt of the receiver it should be removed from the shipping carton and visu-
ally inspected to insure that it has not been damaged in shipment. If it is determined that the re-
ceiver has been damaged in transit the shipping carton and packing material should be saved and 
the transportation company notified immediately. 
 
As part of the initial inspection, all of the front panel controls should be checked to insure their 
proper mechanical operation. It is advisable to generally, look the receiver over and verify that 
nothing has been shaken loose and that everything appears to be normal. 
 
The following items are supplied with each receiver: 
 
1. Instruction manual, ALLIED MODEL SX-190. 
 
2. DC power cable assembly. 
 
3. 1/4" phone plug connector. 
 
4. Additional  feet.

RECEIVER CONNECTIONS 

 
If the SX-190 Receiver is to be used for receiving only and not as part of a system with intercon-
nections to an associated transmitter there are only a few required connections. These connec-
tions are easily accessible at the rear of the receiver and their design permits permanent connec-
tions to be made in a neat manner. Figure 1-2 (page 5) illustrates the connections points at the 
rear of the receiver. 
 
1.2.1  ANTENNA CONNECTION 
 
The SX-190 Receiver has been designed to operate from a 50-75 ohm unbalanced antenna input. 
To obtain the best results from the receiver the antenna that most nearly suits your needs should 
be selected. The illustrations shown in Figure 1-5 (page 7) are typical antenna installations. All 
that is required is to install a PL-259 connector on the feed line and connect it to the antenna in-
put. 
 
1.2.2 SPEAKER 

CONNECTIONS 

 
Instructions for installing the phones plug on the speaker cable are illustrated in Figure 1-3 (page 
6). After wiring the connector, insert in Phones/SPK jack.
