ASTATIC 575M-6 (01) PDF SUMMARY:

What adjustments can be made to the microphone?

The microphone has easily accessible slide controls for volume and tone adjustment, so that the correct modulation level and tone quality can be set for each operator’s voice.

How do I adjust the volume and tone?

At a speaking distance of approximately 2 inches (or the position you prefer) with the external volume control set at 0 and the tone control set in the center position, adjust the volume control for the correct modulation level. Sliding the volume control toward 9 increases the volume. The external tone control should then be adjusted for the most intelligible sound. Slide the tone control toward 0 for an increase in bass response and towards 9 to a decrease in bass response.

How is the 575M-6 powered?

The 575M-6 preamplifier is powered by a readily available, easily replaced, 9-volt battery.

How do I replace the battery?

Remove the rear housing by removing the four screws. Carefully lift off the rear housing. Unsnap the battery from the battery connector and install a new battery. Carefully replace the rear housing and fasten with the four screws previously removed. Depress the switch lever fully while tightening the screws.

What should I do if the microphone plug I have selected for my hookup requirements does not have a cable clamp suitable for the microphone cable?

If the microphone plug you have selected for your hookup requirements does not have a cable clamp suitable for the small diameter high quality microphone cable, use tubing as supplied. Simply slip tubing over cable prior to soldering of lead wires. Position it to ensure proper clamping of cable and tubing by the connector.
