Hifonics ZEUS VII (old School)

My friend just gave me this amp today. It says 600 watts on the front of it. Does anybody know the specs on this amp?

Can someone tell me what kind of harness I need to get the speaker/remote turn on to work.

Thanks
Mike

Get a hold of tech support (if you can).
http://www.maxxsonics.com/hifonics/index2.html

I have 6 of these beasts in the closet. Better
than series 6 and cosmetically looks better than series
8.

If memory serves me correctly ;

300x2 into 4 ohms
450x2 into 2 ohms

Bridged into 4 ohms = 900w

For 600W application, use a 60A fuse,
if you plan to load down the amp to deliver
900W, use a 100A fuse.

The old school Hifonics series 7 amplifiers (class A/B) pack
alot of power in a small chassis. The newer Gen X stuff
is essentially the same design as the old school but has
additional signal processing module capabilities and beefed up
chassis for better heat dissipation. This allowed them
to rate the new GenX series Zeus higher - lol

Make sure you have this amplifier well ventilated if you
plan to run at 900w.

This is one of my all time favorite amps, the internal
beefy powersupply is sweet, I think it outputs +60v/-60V,
in bridged mode that is 120V across your speaker
at clipping - woot!

I may, somewhere, have the wiring diagram, I will check tonight.

Wow-

Thanks!...900 watts at 4ohms!..I just got a pair of Alpine Type-R's Dual 4 ohms that I was planning an amp for.
I guess this will do just fine.


Not bad for a FREE amp!

doh! I only have the Series 8 diagrams
which is a Utilink connector not the
color codes wire harness.

Perhaps a google search can yield
the series 7 wiring diagram. The specs
I stated are correct except they
indicate 90A fuse not 100A.

This was a popular amp in the late 80's
and people back then would blow
up their woofers all the time. How
many woofers back then could
handle the power of the bridged Zeus? LOL

Im assuming that this AMP is FULL RANGE and if I wanted to drive subwoofers with this amp, I'll need a crossover?

I will be using the stock head unit (Bose in a QX4 Infiniti) and it does not come with a subwoofer control/pre-out.


What would you guys recommend I purchase..ALL in ONE "crossover/equalizer/line Driver" or just buy a BIG COIL and place it on the Positive Terminal of the Subwoofer!


Thanks
Mike

I still need the wiring harness diagram..if anybody knows it, please let me know or mail me the diagram.

Thanks

I don't have the diagram, but I will
open up one of my amplfiier and
trace the wires - hehe

Ok, here is the thing. If I remember
correctly, Hifonics has one channel
180 degrees out of phase to make
bridging easy, just use a Y-adapter
on both Left and Right RCA lines
and you tap off the Violet and Grey
wires for bridged mode. It's that
simple.

If you open the amplifier this
is what you see from a wiring
standpoint.

Red = +12v
Black = ground

Orange = turn on wire (+12v)

Channel 1;
Violet = output stage (speaker +)
Green = internal ground (speaker -)

Channel 2;
Grey = output stage (speaker +)
Brown = internal ground (speaker -)

Note, the green and brown wire
are both connected together
to the internal power supply
ground reference so technically
it doesn't matter which one
you use, the important thing
is the violet and grey wire,
one represents the left channel,
the other represent the right
channel. I don't know which one,
but you can try it out once you
connect the amplifier up.

Back the 180 degrees out of
phase issue.

If you connect your speakers
this way as shown above,
one of the channels will be
180 degrees out of phase so you
need to reverse one of the speaker connections on one of the channels
but I don't which one. If you reverse
the wrong one nothing will happen
to the amplfiier, it will work, the only
issue is the input signal would be
180 out of phase with the rest of the
system.


I'm make a guess based on what
I see, this is my best guess on
correct phasing;

Channel 1;
Violet = connect to speaker pos.
Green = connect to speaker neg.

Channel 2;
Grey = connect to speaker neg.
Brown = connect to speaker pos.


If you bridge this amplifier, I don't
know which wire (violet or grey)
is used for positive, if you connected
it wrong, the only issue is phasing,
the amplfier won't be damaged.

If you want to test the phasing
without the use of test equipment
you can connect one channel of
the Zeus to one woofer in a two woofer system, then connect the other woofer to a known good
amplfier. If the bass seems muffled
then the phasing is wrong, reverse
the wires. One configuration would
yield much stronger bass than the
other, then you know which wire is
positive. For bridged mode, do the
same test.

I was able to get a hold of ZED AUDIO and I gave showed him (Steve Mantz) your schematics and this is his reply.

Quote:
CONNECT THE SPEAKER BETWEEN THE VIOLET AND THE GREY WIRES

THE GREY IS ACTUALLY THE (-) OF THE RIGHT CHANNEL AND THE BROWN IS THE (+) OF THE RIGHT CHANNEL

LEAVE THE GREEN AND BROWN WITH NO CONNECTIONS. MINIMUM IMPEDANCE IS 4 OHMS IN THE BRIDGE MODE
Quote:

Violet = output stage (speaker +)
Green = internal ground (speaker -)

Channel 2;
Grey = output stage (speaker +)
Brown = internal ground (speaker -)

I guess Im now confused.

I will try both ways and see what happens.
