INTRODUCTION 

THANK YOU!... 

...for choosing The MANLEY STEELHEAD RC phono preampli

fi

 er

.

  Please read over this 

manual carefully as it contains information essential to the proper operation and maximum enjoy-
ment of this fabulous instrument. 

The MANLEY STEELHEAD RC is designed to provide that rare combination of maximized 

sonic performance coupled with a generous ability to adapt to any moving magnet, moving coil 
or iron vane phono cartridge you may wish to use. With the STEELHEAD’s feature compliment, 
you no longer have to settle for what a given cartridge sounds like with a 

fi

 xed predetermined 

preamp load impedance, or wonder what that same cartridge might sound like when presented 
with different loading arrangements. What best suits your particular phono cartridge, system, lis-
tening room and personal preference is now merely a 

fl

 ick of a switch away! The STEELHEAD 

adapts to accommodate your situation, rather then the other way ‘round. 

To this end you will notice that it is the anticipation of your preampli

fi

 er needs which has 

driven every detail of the STEELHEAD’s planning, engineering, styling, operating convenience 
and adaptability. 

UNPACKING 

Unpack the preampli

fi

 er carefully and make sure that all supplied accessories are present. 

Examine all items for any possibility of shipping damage. All six tubes should be standing at at-
tention in their sockets. If the unit is damaged or fails to operate, notify the shipper or your dealer 
or us or your local authorities immediately. Or if you suspect The Shipping People threw it off 
the airplane and onto your front porch whilst 

fl

 ying overhead at 30,000 feet, notify the ship-ping 

company without delay and complain to them as we only guarantee this unit to be able to survive 
a drop of 23,487 feet or less. 

Your STEELHEAD RC was packed with extreme love and care. Each box includes the fol-

lowing components and accessories: 

a) 1 each, 6 foot IEC 3-conductor mains power cable (that you will probably replace with 

an expensive audiophile cord anyway.) 

b) 1 each, Owner’s Manual per pair (that we hope you will keep reading.) 
c) 1 each, Outboard Power Supply Unit with captive grey power cable and big fat connector.  

        d) 1 each, REMORA Remote Control.

It is prudent to retain the shipping materials for future use, as they are custom-formed for 

the preampli

fi

 er and will greatly minimize the chance of shipping-related damage should you 

ever need to put your precious Steelhead in the careless hands of The Shipping People again.
