Replaced an old Panasonic with a new SL1100. They have a Door King 1812 Classic controller hooked up to co 4. The volume is extremely low where before on the Panasonic it was loud and clear. I tried adjusting the receive and transmit gain upwards but it had almost no affect other than to make it worse.
