No, just for iOS :(

Your only solution is to use VNC on your android connected to a computer with SA or AA.

In Topic: Amplifier for JBL CBT 70j and 70je column array

28 September 2014 - 11:50 PM

Are you going to use just one set (JBL CBT 70j+JBL CBT 70je) or more them one?

Generally speaking, going to 4 ohms bridged or 2 ohm stereo puts allot of strain on the amp so I wouldn't recommend working this way although it is possible to do it reliably and the wattage calculation is what you need for those speakers in this combo. If you plan to use more then one set then I would recommend you buy a single XTi 4002 for every four speakers or every two sets (JBL CBT 70j+JBL CBT 70je).

What did you end up doing?

Sorry for the late reply,
I think your best bet would be to choose amps based on the max power of the drivers you put in your boxes. Just make sure you have sufficient limiting (like you have in the itch and itch HD series amps). What you should do if possible is gain match the amplifiers to compensate for any gain differences you have between your drivers. Say you have a 93db/1W/m woofer and two 99db/1W/m drivers per box, the woofer would be virtually non existent in relation to the mids if operated at the same wattage/gain, you would need to compensate for the sensitivity differences by changing the gain on your amps, either lower the gain on your mid amp or push it on your woofer amp.

For better results you could do is get yourself a good laptop and a simple calibrated USB measurement mic, install rational acoustics smart demo version and calibrate all that you can using a simple one mic measurement rig. If you don't know this already you have quite a learning curve :)

Any more questions I'll do my best to answer faster.

In Topic: XTI4002 and JBL STX825 settings?

you can open audio architect and copy all the setting from an amp that does have those speakers into your XTI.

These are some power hungry speakers. If I were you I'd use speakers that have higher sensitivity and lower wattage.

How do you calculate the box dimensions? why did you choose 3 way design over a simpler 2 way design? Normal magnet vs neo?

Each of the 12" drivers you gave me the link to can handle, if limited properly, up to 3000W each at 8 ohms. That much power would require a powerful amp such as the i-Tech 8000 and the likes.

Best of luck
