It is balanced or not?


Hello everyone, I am new to this page, I thank the Audiogon team for allowing me to be here with you, I have a question: I have the preamp and DAC: "Emotiva Differential Reference XDA-1" it has the following digital inputs: "S/PDIF (optical and coaxial) and AES/EBU (XLR)", the XDA-1 has balanced outputs for an speakers amplifier, inside it has the amplifier: "Texas Instruments Burr Brown OPA2134" and I want to know if it really works balanced; the XDA-1 has the DAC: "Analog Devices AD1955" inside. thanks

Ok, thank you very much, but if I connect the Emotiva to the JBL MSC1?, The Emotiva is digital and it has unbalance and balance output, I want to connect that output to the JBL MSC1, what do you think?
@auxinput I do not understand why it can not be balanced by having a mono and bridge option, it is very rare, that amplifier has been used for many years in professional studios and has even been described as almost high-end. Did you see any diagram of that amplifier to know those details?
Running the sound through the JBL MSC1 is definitely going to degrade the sound quality of the Emotiva DAC, but if that's all you have, that's what you are gonna have to use. 

Is the amp better to use as stereo?  Generally speaking, yes.  It really depends on the speakers and if they drop below 8 ohms, but usually stereo amps do not perform as well in bridged mode.

Generally, a dedicated balanced/differential amp will have power from both the +(RED) and -(BLACK) speaker posts.  In this situation, you cannot bridge amp channels because they are already, in a sense, bridged. 

The service manual does not give a complete schematic, but if you look at page 6-3, you can see the Output Stage schematic.  On the right side of the schematic you can see the output connected to one speaker binding post.  The other speaker binding post is shunted directly to ground, so this is a single ended amp (even though the input stage is balanced).
