4.0 Installation & Placement
The RD-1 as is the case with any tube equipped device is mo e sensitive
than most othe types of audio components to EMI (elect o-magnetic inte -
fe ence) f om powe supplies and moto s including vib ation. Consequent-
ly, it should be placed at a minimum distance of 18 inches f om powe sup-
plies, tu ntables, tape decks, AC line filte s, etc..
One should neve place anothe component di ectly on top of this integ at-
ed amplifie , and as good p actice, it is not ecommended to di ectly place
this component on anothe audio component that gene ates heat.
NEVER PLACE THIS COMPONENT ON TOP OF A LOUDSPEAKER.
Vib ation picked up by the tubes will damage them and sho ten thei useful
life.
When d essing cables, take ca e as to tuck away loose cables so someone
may not t ip on them.
Allow also fo ample ai ci culation a ound the RD-1.

6.0 SYSTEM CONNECTIONS
6.1 The RD-1 is a stand alone Radio with built-in speake s but does p ovide
fo connection to othe audio components that you may wish to use.
(Example: CD Playe connected to Line Input via a pai of good quality RCA
te minated shielded cables.) The RD-1 also has a p e-amplifie output. You
may also use the RD-1 to connect to you sma tphone device and whe e the
RD-1 acts as Bluetooth Speake . (mo e on this late )
6.2 Connect the Radio to the antenna supplied with the RD-1.
6.3 With all input and output connections made, select the p ope input AC
mains Voltage by sliding the voltage selecto to the p ope AC Voltage setting.
6.4 Use the supplied AC powe cable connecting it to the IEC eceptacle
located on the ea panel of the integ ated amplifie ’s chassis. Ensu e that the
AC wall outlet you use has a functioning g ound. Then, it is p efe able that
you plug you RD-1 into a su ge supp esso powe ba used as well fo you
othe audio components, then best is to connect this di ectly into a dedicated
AC outlet. Best to avoid using an extension co d.
NOTE: In o de to obtain the maximum pe fo mance f om you audio system
we st ongly ecommend that the detachable powe co d does not come into
physical contact with any of the inte connect cables unning to and f om you
RD-1. In the event that this can’t be avoided, you should ensu e that any ca-
bles coming into contact with each othe a e c ossed at ninety deg ee angle to
