Pioneer SA-9500 AC outlets

Hi Everyone. I have just joined here. Have been the receiver of amazing information any time I had a problem or concern...so thanks.
I have an SA-9500 which is running 240v as I am in Australia. I have just acquired an equaliser SG-9800 which is 120v. Can this be plugged into the AC OUTLETS on the side of the SA-9500 or will I still need a converter?

Thanks in advance

Do not plug a 120v component into the ac outlets of a unit running on 240. There is no voltage conversion inside an SA-9500. The SG-9500 may be convertable though.

Enjoy,
Rich P
 
Thanks for that Rich P...I thought as much but because the side outlets are a two pin prong like the US style I thought that maybe these outlets only run 120v as the unit is 120-220/240v model.
 
G'day Harry and welcome aboard.
I too reside in Sydney and it also turns out we are both born the same year too lol !
The question you raised is a good one.
I have an SA -7100 ( multi voltage ) and my AC outlets are the same as you described. They do look like they are meant for U.S. style plug.
I suspect they did it this way for when the unit is operating on U.S. voltage, that is if its a multi voltage unit. Im not really sure. Seems plausible.
Perhaps someone can clarify this.
I have an assortment of 240v and 120v gear and have invested in a quality step down transformer with 2 outlets for when I use my U.S. stuff.
Cheers mate :thumbsup:
 
Thanks for the reply Awesomeaudio. It would be great uf someone could clarify. It would make life easier if it were the case. Anyone??
 
You could clarify it yourself with a VOM ... (nudge nudge)

I'd assUme though, that those sockets are fed whatever the rest of the unit is set up for. They're mostly a direct pass through in most cases, switched via a relay or unswitched.

I did that some time back in this thread. Here is the bottom line: There is no step down transformer in the unit. What comes in the power cord goes out on the convenience outlets, whether switched or not. The output of transformer(s) are voltages useful to the generation of internal power supply voltages. Ignore me at the peril of your equipment.

Trying to sum up...
Some amps come with AC sockets for the connection of additional equipment, typically a turntable.
These sockets provide mains AC, eg, 240V in, 240V out on ALL sockets. They are normally
rated at 10A, 250V (Not OK for Aust because of transients) and maybe 200Watts

The sockets may be labeled as SWITCHED or UNSWITCHED.
SWITCHED sockets will only be live/deliver power if the amp is turned ON
UNSWITCHED sockets will be live/deliver power regardless if the anp is ON or OFF
(assuming amp is plugged in wall socket and powered ON there).

The SG-9800 may have a voltage selector at the back where you can select 240V, only
after switching to 240V on the SG can you plug the SG into the amp.

If there is no voltage selector on the SG then there is a remote chance the transformer
can be rewired to 240V, however this is extremely unlikely since Pioneer would have
provided the "voltage selector" option.

You will most likely need a step down transformer (240/230Vac -> 120Vac). Autotransformers
are the cheapest but do not provide isolation. I would not buy one. Prefer a torridal transformer
over the old EI type (lower noise, power consumption...) maybe cost AUD200- or DIY for AUD150?

To be honest, I wouldn't bother with the SG. You have a decent amp, spend the $200- on a
partial refurb on the amp if needed.
 
I agree with you mbz on 2 points.
1. Be aware of SWITCHED and UNSWITCHED sockets. Can I just clarify also ?
If the Amp unit is a 240 v unit and not a multi, then the plug ins should also provide 240v.
If it's a multi voltage, then the plug in just may be wired to U.S voltage, hence the need to meter the sockets ? Or Does the plug in sockets also switch in accordance with the selected voltage ?
2. I too wouldn't bother with the SG. If you must have it to complement the line up, then get yourself a decent "ISOLATED" step down transformer.
I recently purchased myself a N.O.S 2000w Isolated step down from the bay, which was originally manufactured by Tortech Industries. I use this for all my monster amps on U.S Voltage.

Both SWITCHED and UNSWITCHED sockets provide MAINS voltage regardless of voltage selector switch position.

Maybe the attached pix will clarify. It's from a yamaha CA-2010 showing from left to right the power cord/socket then 3 UNSWITCHED sockets
then the power switch then the SWITCHED socket (SWITCHED=after power switch) then the circular voltage selector and the transformer beneath it.
