Than you very much to all!!!!! thank you than you :-) yes stringreen, the Crown D-75 and Crown D-75A are balanced, they are studio amplifiers(pro) oh ok gdnrbob.
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

@joser9616 - One point. Just because they are "studio amplifiers" does not mean they are fully balanced. The analog input stage of the amp may be balanced, but the amplifier itself is single-ended. You can tell because the amp can be bridged-mono to double the power output. You would not be able to do this on a balanced/differential amplifier. In actuality, pretty much all studio equipment is not fully balanced. "XLR balanced" was developed as a way to transfer analog signals between equipment devices, sometimes a very long distance (50-100+ feet). In almost all cases I have seen, the XLR input on a studio equipment will always convert to single-ended analog internally for purposes of volume / equalizer / mixing / etc. Then, on the output, it will convert back to "balanced XLR". |
Please people, which of these two amps have better audio quality? thanks: http://www.ti.com/product/MC33078 it is inside a JBL Professional MSC1Studio Monitors Controller http://www.ti.com/product/OPA2134 it is inside of a Emotiva DAC Preamp XDA-1 thanks. |
The op amp is a factor in sound quality, but it's never the full story. You also need to look at power supply, etc. The fact that the JBL uses a switching wal-wart power supply is an indicator of poor sound quality. The JBL is meant as a cheap mixer / room correction unit. I believe the Emotiva would have highly superior sound quality, especially since it has a fully discrete output stage. |
