Atlas Sound TSD-RL21 Two Channel Mixer

Versatile 2x1 Mic/Line Mixer for Professional Audio Management
The Atlas Sound TSD-RL21 is a powerful 2x1 mic/line mixer designed to meet the diverse needs of modern audio environments. This compact unit excels in applications requiring paging, public address, and background music capabilities. Whether you're managing audio in a conference center, football stadium, gymnasium, or retail/hospitality setting, the TSD-RL21 provides the flexibility and control you need for seamless audio integration.

Flexible Input Options for Various Audio Sources
Channel one of the TSD-RL21 offers remarkable versatility with its rear panel dipswitch, allowing you to configure it for either microphone or line-level input. This adaptability ensures compatibility with a wide range of audio sources, from professional microphones to line-level devices. Channel two features a stereo summing RCA line-level input, perfect for connecting consumer audio devices or background music sources. This dual-channel design allows for easy mixing of announcements with background audio, essential for many public spaces.

Professional-Grade Audio Quality and Control
The TSD-RL21 doesn't compromise on audio quality. With up to 50dB of gain available for the mic input, it ensures clear and powerful voice reproduction, crucial for paging and public address applications. The balanced line output maintains signal integrity, even over long cable runs, thanks to the high-gain output option. Front panel controls with removable knobs allow for precise adjustment of both inputs, while the option to replace these with security covers prevents unauthorized tampering - a valuable feature in public installations.

Remote Level Control for Convenient Operation
One of the standout features of the TSD-RL21 is its remote level control capability. Compatible with the Atlas Sound AAVC-10K decorative wall plate control (or equivalent), this feature allows for remote adjustment of either the entire mix bus or just the RCA input on channel 2. This flexibility is invaluable in installations where the mixer might be rack-mounted or otherwise inaccessible, allowing staff to easily adjust volume levels from a convenient location.

Visual Monitoring for Optimal Performance
Effective audio management requires clear visual feedback, and the TSD-RL21 delivers with input peak and signal indicator LEDs. These visual cues allow operators to monitor levels at a glance, ensuring optimal signal strength and preventing overload. This feature is particularly useful in dynamic environments where audio levels may fluctuate rapidly, such as sports venues or busy retail spaces.

Flexible Installation and Integration Options
Designed with professional installations in mind, the TSD-RL21 offers multiple mounting configurations and a cable management system, making it adaptable to various setup requirements. The inclusion of removable Phoenix-style I/O connectors facilitates easy installation and maintenance. Separate ground connections further enhance its flexibility, allowing for clean audio in various installation scenarios and minimizing the risk of ground loop issues.

Versatile Applications Beyond Standard Use
While primarily designed for mixing and paging applications, the TSD-RL21's features make it suitable for a variety of audio tasks. It can function as a standalone mic preamp, line preamp, stereo summing preamp, or line driver. This versatility makes it a valuable tool in any audio professional's toolkit, capable of solving a wide range of audio routing and processing challenges in diverse environments.
