OPERATING INSTRUCTIONS  
Intended to alert the user to the presence of uninsulated  
"dangerous voltage" within the product's enclosure that may be  
of sufficient magnitude to constitute a risk of electric shock to  
persons.  
Intended to alert the user to the presence of important operating  
and maintenance (servicing) instructions in the literature  
accompanying the product.  
CAUTION: Risks of electrical shockÑDO NOT OPEN  
CAUTION: To reduce the risk of electric shock, do not remove cover. No

personnel.  
UAª 35T II  
Utility Amplifier  
 
connection is between the COM terminal and the 25 V or 70 V  
terminal.  
MIC/PAGE SWITCH (7)  
Selects between mic and page input. The page selection  
provides internal pad, converting this input to line level for page  
applications.  
FUSE (10)  
The fuse is located within the cap of the fuseholder. It the fuse  
should fail, IT MUST BE REPLACED WITH THE SAME TYPE  
AND VALUE IN ORDER TO AVOID DAMAGE TO  
THE EQUIPMENT AND TO PREVENT VOIDING THE  
WARRANTY. If the amp repeatedly blows fuses, it should  
be taken to a qualified service center for repair.  
INPUTS (8)  
Low Z mic/page inputs are provided via screw terminals. Screw  
terminal AUX inputs are paralleled with AUX RCA jacks. (See  
AUX IN (5).)  
OUTPUTS (9)  
WARNING: THE FUSE SHOULD ONLY BE REPLACED  
WHEN THE POWER CORD HAS BEEN DISCONNECTED  
FROM ITS POWER SOURCE.  
A direct output, as well as several transformer outputs, are  
provided to allow the proper interface between the amplifier and  
the speaker system. The direct output allows direct connection to  
a 4 ohms speaker system. Connect the speaker (or speakers)  
from the GND terminal to the 4 ohms terminal. For 8 ohms  
speaker systems, connect between the COM terminal and the 8  
ohms terminal.  
AC LINE CORD SOCKET (11)  
Provided to accept the removable AC line cord. Connect only to  
proper source--see back panel markings.  
POWER SWITCH (12)  
Used to turn AC mains power on or off.  
25 V and 70 V outputs are also provided for Òconstant volt-  
ageÓ speaker distribution systems. The 25 V and 70 V output

According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Ear plugs or protectors h1 the  
ear canal]s or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss if exposure is  
in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high Sound pressure levels. it is recommended  
that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification system be protected by hear-  
ing protectors while this unit is in operation.
