Ultra-compact, 2 channel audio monitor that fits perfectly in a network facility or OB truck for live events.  This makes the AMP1-2SDA+ ideal for a range of applications where basic, but reliable audio monitoring is required.


Wohler has distilled 25 plus years of knowledge and experience into our AMP1- 2SDA product.  This unit has Wohler build quality, a shallow depth of five inches, and great pricing.  Fast selection and monitoring of any available pair of audio is available via either 1 x 3G-SDI (with looped output), 1 x AES3 input pair, and either of 2 pairs of Analog inputs (Balanced or Unbalanced).  An additional 8 pairs of both Analog and AES3 on 3 x DB-25 inputs are included on the AMP1-2SDA+ model.  Analog and AES3 outputs of the selected pair are included in the unit for external monitoring.


Designed with simplicity in mind, the AMP1-2SDA provides two rotary controls that allow the user to easily select a source with the first and then move through that source’s corresponding audio pairs with the second.  A large front panel screen, highly visible to users, displays the selected source and monitored pair, along with brightly displayed levels on  2 x 26 segment LED meters.  Additional features include simple tone controls for adjusting audio output and an audio trim control for altering the analog output levels.
