Re: The buttons that are confusing/concerning me are the "HDMI", 2CH BYPASS", "Digital", and "Stereo" buttons.
I was hoping there were discrete I/R codes for their operation, but it appears only the "Digital" and "2ch bypass" have discrete codes.
The "HDMI" and "stereo" buttons only have toggle control, correct?
There are discrete codes for ANALOG, DIGITAL,HDMI and 2CHBYPASS. Those selections are exclusive, selective, selecting 1 of 4
automatically switches off the other 3 off. Thus there is no real need for separate OFF selections (digital is an exception carried over from SP2).
2CHBYPAS ON = 053
ANALOG ON = 054 (note: analog does not have a LED on the front panel, but it is indicated by switching off the other three LEDs)
HDMI ON = 055
DIGITAL ON = 056
Similarly, STEREO, SURROUND and MONO are exclusive modes when select 1 automatically deselects the other 2.
MONO ON = 052
STEREO ON = 018
SURROUND ON = 017 (this is normal mode for
To send a code, press CODE button momentarily on the BR3 infrared remote, then key-in the 3 digits on the numerical pad (see manual).
To program a Pronto compatible controller, see the attached hex file as an example.
Re: In addition, in trying to figure out how those options all work with each input. Are they volatile or static for each input,
and if they are volatile, what is the default option for each of those buttons when you switch to a given input?
They are normally non-volatile. Whenever you select any of the setting sources or alternative inputs like HDMI DIGITAL etc, they
are automatically saved within 2 seconds, then restores any time you select a particular source button. If you power it down,
next time on power up it will restore the last used settings and selection including volume (this can be overriden).
Re: She uses the remote to select HDMI 1 as the input. If that stereo button is still on, she'll get a stereo downmix ...
Yes. STEREO selection is associated and saved together with the source button used. If you re-select source 1 (HDMI1) then it will reselect STEREO.
You have to manually de-select stereo. Stereo status is indicated by its LED so it is easy to notice.
The same with the 4 alternatives ANALOG/DIGIT/2CHBP/HDMI - they are associated with each source button. The first 8 source button
is associated with 1 of 8 HDMI input (but you have to select HDMI alternative to enable it).
That behavior can be overriden by AUTO SAVE=OFF parameter, in that case no automatic saving will be performed.
Re: How does the headphone amp compare to the bha1? Would the amp in the SP3 make the BHA-1 redundant for my application?
SP3 headphone output is meant for monitoring only. BHA-1 has higher quality output (lower THD than the SP3
headphone output under a realistic headphone load, for example 16 ohm), and also higher output power than SP3.
I hope it helps,
