2.5.1 Speaker wire terminals (BINDING POSTS)
We should use wires with “banana” or “fork” connectors, the second (fork) being
more reliable in the long run (the “banana” terminal gets loose in a short time).
We can see that on each amplifier output channel there is a pair of lugs. The
speaker positive should be connected, and the terminal with
red lug
is to be
regarded as
“hot”
, which should
never be connected directly to the ground
. The
other side of the speaker should be connected to the black lug.
Never connect any wire directly between the left channel
lugs and those of the right channel and vice-versa.
2.6 Connecting the power of your 4-ohm Z series:
Your
Studio R
power cable has 3 wires with a 3-pin connector. The
4-ohm Z
Series
amplifiers are designed to operate on 110 V or 220 V.
Under full power, with both channels set to 4 ohms (Two 8-Ohm speakers in
parallel per channel), your
Studio R 4-ohm Z Series
amplifier can “pull” a
considerable current. See on the following table the recommendable minimum
gauge to use on your AC electrical installation according to the number of
speakers to be used and the type of music.
SPEAKER OUTPUTS:
This is
where the speakers should be
connected. Connect the
speaker positive to the
positive lug, and the negative
to the speaker negative
.
Floating common:
Your amplifier circuit ground is insulated from the frame. This allows
various safety configurations to be made for the system grounding.
WHEN WE SELECT THE LINE VOLTAGE ON
WHICH THE AMPLIFIER WILL OPERATE, IT IS
VITAL TO PLACE THE FUSE WITH THE PROPER
CURRENT VALUE. SEE THE CORRECT VALUE
ON THE FUSES TABLE.
