bose 802 eq

My 802 controller has gone defunct. Does anyone know how to emulate it with
a good graphic until I either get it it fixed or get another?

All ideas very welcome and thanks in advance for any answers.

All the best,

Brian

Yes I know! Many thanks for the kind sympathy and empathy but the 802s are
just right for our band sound - mainly acoustic, no big bass etc.

Any helpful suggestions?.....

The old "California Curve" or "Smile" eq curve is what I think a previous
previous writer was refering to.

By themselves, the 802's make very little audio below about 150 Hz, so boosting
125 Hz and down will help. The same goes for frequencies above 5-6 KHz. Start
boosting in a gradual manner. Thus the "Smile" EQ term. When you look at the
the position of the faders, they will make a "smile."

The 802's are fairly smooth in the mids, but there maybe a couple of
frequencies you'd be better of dipping out to prevent feedback. Just ring them
out by ear.

Be careful to not overdrive your speakers. Just because a little EQ is good,
that does not mean a lot of EQ is better. If you hear distortion, back off on
things.

Are you implying that Bose's EQ of them is not good?

Back in 1979 the controller clipped on 20 kHz 0 dB sinewave because of
the extreme boost applied. I would except that issue to have been
resolved way long time ago, but if additional EQ is required on top of
the EQ provided by their controller, then it could make sense to have
only one EQ.

Perhaps Dave can help and fix it, if I ended up posting something that
was not up to newsgroup specs in terms of quality. (QC = signing the
crap out so it can be delivered ... don't tell me otherwise, by
daytime-job is currently as quality control inspector ...).

(And snip from your other post "sliders may not move that far")

I actually vaguely recall a blurb from Bose a long long time ago
cautioning users from using a conventional EQ to do the job, because it
may not be capable of EQing to that magnitude.

Brian,

If you have access to a PC with a sound card that accepts pro-levels,
you could take your EQ and run the same procedure that I did, this time
adjusting your EQ to match the frequency plot that I posted. You would
want to drive the EQ at the same level as you would the 802 controller,
and then look at the output file to make sure it was not clipping.

We have an 802 controller. I scanned it for you.

http://www.audiorail.com/802_controller.zip (89 KB)

Source is white noise, 10 seconds. Red is straight wire. Blue is EQ.
High/low cut buttons out, 802-only mode. (No 302 connected.)

You should be all set to emulate.

[brian]

Many thanks to all indeed! My mistake if I mistook the smile!
Cheers,

Brian

Wow, that is some serious EQ compensation for a shitty box.

Thanks for that. My main system in the ship's main lounge is Bose 802
and 302 (installed by someone who bought into the Bose myth that it is
acceptable gear), at least until I manage to persuade them to get
something decent in and one of our controllers keeps dying. Will get a
DEQ2496 and be done with it.

We have Bose waveradios in every cabin on the ship. Sadly whoever
thought to put them in forgot to check the mains frequencies were
compatible and now all of them are useless because they suffer from
drummer disease (can't keep steady time).

Went strolling though a local large furniture and appliance store
recently. There sat a freestanding end cap display (with small lcd
screen) for the bose home theater system. $2400. On the other end of the
building was home theater in a box for $300. And about the same sized
speakers. Granted, for $300 you get what you get. But $2400 for a bunch
of tiny speakers? Talk about selling snake oil.

Of course, i take a green magic marker and draw a line around my
speakers. It improves there power handing by 50% ;)

Why did the blind sound engineer go to work cruise ships?
Because he could always "sea" at work........

Note I said "(No 302 connected.)" The 802 controller automatically sets
up a different EQ curve for the 802 when you plug something in the "302"
outputs. Do you have something in the 302 outputs?

Yeah, a 302. My front fills however do not have the shittysub attached
so I can just yank their controller and use that on the side fills,
saving the soon-to-be-acquired DEQ2496 for the front fills.

I was just fishing to see if you needed me to run the scan again on the
802 controller outputs in the "302 biamped" configuration.

Garth, I could use the 302 plot. Thanks for the one you already posted.

Okay, here it is:

Loading Image...

This has all three configurations color coded in the same plot, and this
time 100 seconds of white noise used for a finer granularity (instead of
10 seconds before.)

I deleted the old "802_controller.zip" that I had originally posted.
I've got a better graphics utility for creating efficient GIF files now,
so hopefully more user friendly.

[Paul Pinyot]

Garth,
Thanks very much! That is slick. What program/software did you use to
generate the response curves? I hope to return the favor someday.

Audition or CoolEidt

He might have gotten smoother plots with the Audio Righttmark program, but
these seem way good enough.

Having that plot will be very useful - thanks for taking the time to do it

Use your EQ to EQ the same way you would any system.

Measure frequency response at a distance of one or two meters and
compensate sensibly as you would with any other box that needs default
eq applied. Notice the wording, most people that EQ seem to add way too
much treble to a response that should not measure linear to sound right.
At 10 feet the box should be 6 dB down at 16 kHz, probably with a gentle
roll-off above 1 kHz. The net effect will be that 1 kHz appears to be
slighty boosted, that may however be seen as a voice projection
advantage.

The Behringer digital eq _could_ be a wise idea .... I don't know how
the Bose controllers are implemented nowadays, but there was room for
improvement back in 1979 according to Hugh Ford's (as I recall this)
test of it in Studio Sound.
