Introduction and Performance Features
Important Information
1 Caution: To prevent electrical shock make sure that the AC
POWER CORD IS NOT CONNECTED TO THE SE84ZS when
inserting or removing Vacuum Tubes, as there are hazardous voltages present at the pins of the Tube Sockets.
2 When Vacuum Tubes are installed or removed make sure to seat
them properly in the tube sockets. A properly installed Vacuum
tube should seat all the way down making the tube pins no longer
visible.
3 If the SE84ZS has been on , understand that the tubes will take
time to cool off before they can be safely removed.
4 For additional connection information, refer to the owner’s manual
for any components connected to the SE84ZS.
5 It is very important that loudspeaker cables of adequate size be
used, so that there will be a minimum power loss. The size is
specified in Gauge numbers or AWG (American Wire Gauge). The
smaller the Gauge number, the larger the wire size.
6 Connection Terminals will accept up to a 8 AWG wire size:
If your loudspeaker cables are 50 feet (38.1m) or less, use at
least 14 Gauge. If your loudspeakers are 100 feet (76.2m) or
less, use at least 12 Gauge. NOTE: Beyond power loss, there
can be other sonic reasons to employ larger Gauges.
DECWARE makes a speaker cable guaranteed to be in the top 5%
sonically regardless of price, called ZENSTYX. It is often recommended with this amplifier even in shorter lengths of 10 feet.
Connector Information
The SE84ZS is fitted with what are called
“single ended” RCA type input connectors.
These are located along the rear of the amplifier. Another popular type of connector is
known as XLR or “balanced” inputs. The
SE84ZS does not use balanced inputs because
contrary to popular belief they do not automatically sound better. Balancing is a system wide
concept developed for pro audio to reduce noise
an facilitate long cable runs of in many cases
over 100 feet.
Fuse location / Information
The fuse is integrated into the IEC power cord
connector at the back of the SE84ZS.
Use a
GMA
(20mm x 5mm) 250 volt
3 amp fuse only.
TO ACCESS FUSE, REMOVE POWER CORD and
PRY FUSE HOLDER LOOSE WITH SMALL
SCREWDRIVER AS SHOWN.
The fuse holder contains a spare fuse as
shown. To reinstall just snap the new fuse in
place and snap the fuse holder back into the
IEC connector.
The speaker binding posts are designed to facilitate the use of bare wire by inserting it in the
horizontal hole and tightening the post down
onto it. They can also accept a spade connector
with the same tightening technique. In addition
there are vertical holes visible in the top of each
binding post that are designed to accept banana
jacks.
BOTH INPUT AND OUTPUT CONNECTORS are
color banded to indicate left / right or positive /
negative. The RED is POSITIVE or RIGHT
CHANNEL.
WARNING
NEVER INSTALL A FUSE WITH A
HIGHER RATING THEN SPECIFIED.
NEVER ATTEMPT TO BYPASS THE
FUSE OR DEFEAT ITS INTENDED
PURPOSE !
