CONNECTIONS
15.0 x 10-6
4 - L E A D STEREO CONNECTION:
Connect "hot" lead of right
channel to terminal "R" and shield or ground lead of right chan-
nel to terminal "RG."'
Connect "hot" lead of left channel to ter-
minal
"L"
and shield or ground lead of left channel t o "LG."
To prevent "ground loops" and hum, no common connection
should be used a t cartridge terminals.
M O N A U R A L CONNECT I O N
: For single channel reproduction of
Monaural or Stereo record~ngs, connect "hot" lead to both " R
and "L" terminals and connect ground or shield lead t o both
ground terminals marked "RG" and "LG."
C A U T I O N :
Do not make solder connections to cartridge terminals.
Make all solder
connections
to terminal jacks provided before s l i ~ -
ping them over the terminals.
