Lynx LM-A24 Analog I O Module Owner’s Manual

Lynx LM-A24 Analog I O Module

Product Information

The LM-A24 and LM-A4 are specialty analog modules designed for the Lynx Aurora(n) Converter. These modules provide line-level input/output on TRS connectors and are built to the high standards that Lynx converters are known for. They offer pristine transparency, excellent imaging, and ruler-flat frequency response.

These modules are ideal for installations that require a small number of dedicated I/Os without the need for an additional breakout cable. They also offer I/O levels up to +24dBu, ensuring compatibility with other professional studio equipment. One example application is using these modules to provide separate monitor outputs while feeding other Aurora(n) line outputs to a summing mixer.

The LM-A24 and LM-A4 feature output anti-pop relays that provide protection for monitor speakers. The LM-A4 is an output-only module that can be used alongside the four-channel LMPRE4 input-only module to create a cost-effective 4-in/4-out Aurora(n) configuration, perfect for smaller studios and podcasters. Additionally, this configuration allows for future expansion by adding more channels of line-level, AES/EBU, or ADAT I/O.

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

Product Usage Instructions

1. Connect the LM-A24 or LM-A4 module to the Lynx Aurora(n) Converter using TRS connectors.
2. If using the LM-A24 module, connect line-level audio sources to the LINE INPUT connectors on the module.
3. If using the LM-A4 module, ensure that it is connected to the Lynx Aurora(n) Converter properly.
4. If necessary, adjust the input trims on the Aurora(n) front panel or use the NControl application to optimize the input level.
5. Set the desired output level using the low-distortion, digitally-controlled analog attenuator on the LM-A24 or LM-A4 module.
6. If needed, use the Aurora(n) front panel or the NControl application to route and mix signals as required.
7. To protect your monitor speakers, ensure that the output anti-pop relays are activated.

Specialty Analog Modules for Lynx Aurora(n) Converter

The LM-A24 module expands the capabilities of the Aurora(n) platform by providing two line inputs and four moni-tor outputs on TRS connectors. The outputs incorporate precise level control making them ideal for driving monitor speakers or interfacing with other studio devices. The module easily integrates with other I/O channels since its trans-parent performance matches previous Aurora(n) line-level modules. The LM-A4 is an output-only module which is a lower cost option for applications that do not require additional inputs.

• 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 provid-ing separate monitor outputs when other Aurora(n) line outputs are being fed to a summing mixer.
• The outputs can easily drive powered monitors and offer precise level con-trol 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.
• 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. This can also act as a starter configuration with plenty of room for adding more channels of line-level, AES/EBU, or ADAT I/O.
• 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.
