The other red speaker output binding post is marked “4 Ohm” and
may be used with 4 Ohm speakers. If you are uncertain whether your
speaker system is specified as 4 or 8 Ohm, try the following test once
all other connections are made and the amplifier is operational.

speakers connected to the 8 ohm connections and then the 4 Ohm
connections respectively. The selection that produces the best
frequency balance and maximum dynamics should be used.
The OTO SE Phono utilizes an IEC 320 mains inlet socket. Use the
supplied mains cable to connect the unit to the local mains supply.
The mains fuse and a spare is located in the inlet socket fuse drawer.
Special Note – Make sure that all connections are tight and clean. For
best results use good quality audio interconnects. Although it is
perfectly acceptable to use cables manufactured by other companies,
for best results and performance, we recommend our own
(UK) range of interconnects and loudspeaker cables. For further
information, please consult your nearest Audio Note (UK) dealer, or
