ARS 500 Subwoofer Amp + A/V Switch (1 Viewer)

[ClemensHelberg]

Hello,

I have recently bought one of these ARS 500 subwoofer amps made by sunfire.

The build quality is perfect, but unfortunately the map came without owners manual.

Yes, nearly everything of a subwoofer amp is selfexplaining besides that front mounted control panel with volume control and A/V switch.

Could anyone suggest me where the A/V short cut is standing for? Does the A stand for audio (maybe without low frequency boost) and V for video ( with boost)?????????

The amp is used together with a Stryke SAE 1204 in a 80 liter vented cabinet. There is no change hearable using the A or V position.

Thank you very much for your help.

Bye

I would guess that indeed it was an Audio/Video switch. Setting it to Video for a little boost in the lower end to get more BOOM out of it for movies or to Audio for a flat response. That's just a guess of course. Do you have a link to that amp?

Clem,

I too purchased the Sunfire TDC Amp from a ARS-500 and
yes the A/V Switch stands for Audio/Video and there is a
boost on Video. It seems pretty flat on Audio but I have
not measured the output at every Hz to see if there is any
boost on the Audio setting (doesn't sound like it to my
ears)

What an amp ehh!

Betcha you got it from ESSurplus off Ebay huh?

Hello,

Yes, I have bought 20 pieces of them from ESSurplus. They are perfect for Germany because of their voltage requirement of 240 Volt. Most of them will be given 1:1 to my friends, the few remaining might be sold through Ebay later.

I am very satisfied with the amp, but unfortunately my ears are maybe too bad to hear the difference between the two A/V settings. :-(

Maybe there is way to measure the different response of the subwoofer with my notebook?

Have a nice weekend!

Clem,

You can measure the output with a simple multimeter and
a cd disk with tone sweeps from 15 or so Hz up into the 120
Hz range. You can measure the output of the amp and if there
is a noteable jump at one specific frequency (like 30Hz)
then there is a boost.

I can most certainly hear the difference between A and V
and it leads me to believe Audio is pure and Video is Boosted
from what I heard with my own ears.

And those ARS500 amps will work in the US too.. The voltage
input is flexible up to 250V 50 or 60 Hz... I run my ARS500
which has the Euro 240v @ 50Hz label on 220v @ 60Hz
