The AMP1-2SDA from Wohler is a 1RU, 2-channel, 3G/HD/SD-SDI, AES, and analog audio monitor with a powerful audio amplifier to help overcome ambient noise. The unit provides the instantaneous selection and monitoring of any available pair of audio from either a 16 channel SDI (with looped output), a single AES input pair, and either of the two pairs of analog inputs (balanced or unbalanced). Analog and AES outputs of the selected pair are included. Additional optional hardware inputs cards can provide up to 8 additional pairs of both Analog and/or AES on DB-25 inputs. The unit features adjustable volume and balance controls, while two on-board 26-segment level meters provide accurate audio level metering. You can visually and audibly monitor any selected audio pair. There is also a 4-digit, 14-segment display for setup and status display.

The AMP1-2SDA is small, low-cost, reliable, and simple to operate. There is very little configuration necessary, as the unit ships already configured to the most commonly requested settings. However, should you need to change these settings, you can quickly and easily access the optional settings using the front panel controls and the Status Display.
