Q:One of our customers gave us a 857AMLa to use in their installation without the power module,will it work by connecting it directly to a DSP mixer with phantom power?
A:No, the power module is needed inline.
Q:Does It come with the transmitter? If Yes, is the Transmitter compatible with ATW-R10?
A:No. This is just the microphone. You may use the U857ALcW with an Audio-Technica UniPak transmitter.
Q:Our church was given an AT 8570 MLa gooseneck microphone. It has hardly been used, but looks like it has been discontinued. Can we use it on our lectern; or should we be looking at something newer.
A:The U857AL can be used with the AT8601 Microphone Desk Stand as long as you use the AT8664 cable pass-through adapter that is provided with the microphone between the stand and the microphone. The adapter allows the mic cable, which exists form the bottom of the gooseneck, to exit from the side of the adapter just above the stand.
