Manufacturer's Description from Lynx

The LM-A24 and LM-A4 are specialty analog modules that provide line-level I/O on TRS connectors. Designed to the same exacting standards Lynx converters are known for, they offer pristine transparency, excellent imaging, and ruler-flat frequency response.

These modules provide an excellent solution for installations requiring a small number of dedicated I/O’s without the requiring an additional break-out cable. They also offer I/O levels up to +24dBu for extended compatibility with other pro studio equipment. An excellent example application is providing separate monitor outputs when other Aurora(n) line outputs are being fed to a summing mixer or to a patchbay for inserts.

The outputs can easily drive powered monitors and offer precise level control via a low-distortion, digitally-controlled analog attenuator. This analog-domain attenuator maintains a high signal-to-noise ratio over the adjustment range. Monitor speaker protection is provided by output anti-pop relays.

Input trims, output levels, signal routing and mixing are easily controlled from the Aurora(n) front panel or using Lynx’s NControl application on any Windows or Mac computer.

These modules are user-installable either in the top position of module 1 or below the LT-USB or LT-TB3.  For Dante and ProTools HD connection methods the LM-A24 or LM-A4 must be installed in the top position of module 1.


Key features

  • Lynx proprietary 24-bit A/D and D/A conversionFour electronically balanced outputs on TRS
  • Output level adjustments in 0.5dB increments up to +24dBuTwo electronically balanced inputs accept levels up to +24Bu on TRS (LM-A24 only)
  • Fully-differential transparent designLine level performance identical to LM-AIO8E
  • Anti-pop relays on outputs for silent power-ups and -downsSeamless integration with Aurora(n)’s mixing and routing engine



The output-only LM-A4 is an excellent companion to the four-channel LM-PRE4 input-only module. The combination of these two modules allows for the configuration of a lower cost 4-in/4-out Aurora(n) which is ideal for smaller studios and podcasters.



Featuring two analog inputs and four analog outputs, all on Balanced 1/4″ TRS jacks, the LM-A24 is the perfect addition to your 8, 16 or 24 channel Aurora(n). The two analog inputs are switchable between +20 dBu and +24 dBu, making them more compatible with other professional equipment (mic pres, etc.). Outputs are identical to the LM-A4 module.
