Signal Path Planning
Effective signal flow design follows these principles:
- Input Stage: Capture and condition incoming audio signals
- Processing Stage: Apply necessary audio processing (EQ, dynamics, effects)
- Routing Stage: Direct processed signals to appropriate outputs
- Output Stage: Final level adjustment and signal delivery
Example Signal Flow
Microphone Input → Input Block → Gate → Compressor → EQ →
Matrix Mixer → Level Control → Output Block → AmplifierTTP (Tesira Text Protocol) Commands
The Tesira Text Protocol (TTP) is the command-line interface that enables external control systems to communicate with Biamp DSP devices. Mastering TTP is essential for integrating Tesira systems with Crestron, AMX, Q-SYS, and other control platforms.

}FAQ
General Tesira Programming
Q: What's the difference between TTP and Tesira software programming?
A: Tesira software is used for designing the DSP configuration - creating signal flows, connecting blocks, and setting up the audio processing architecture. TTP (Tesira Text Protocol) is the command-line interface used by external control systems to interact with the configured Tesira system at runtime. Think of Tesira software as the "design time" tool and TTP as the "runtime" control interface.
Q: Can I control Tesira systems without using TTP commands?
A: While TTP provides the most comprehensive control interface, Tesira devices also support basic GPIO control, RS-232 commands, and some models have built-in web interfaces. However, for full integration with professional control systems like Crestron or AMX, TTP is the recommended and most capable method.
Q: How many simultaneous TTP connections can a Tesira device handle?
A: Tesira devices support up to 10 simultaneous TTP sessions. However, for optimal performance and to avoid conflicts, it's recommended to use a single control connection per device and implement proper session management with keepalive commands.
Signal Processing and Audio
Q: What's the maximum processing latency I should expect in a Tesira system?
A: Tesira systems typically introduce 1-3ms of processing latency depending on the complexity of your signal processing chain. Simple routing and level adjustments add minimal latency, while complex processing like automatic mixing, advanced EQ, and dynamics processing can increase latency. Always test actual latency in your specific configuration.
Q: How do I optimize automatic microphone mixing for speech intelligibility?
A: For optimal speech intelligibility with Tesira's automatic mixer:

,[object Object],
,[object Object], set ,[object Object],:,[object Object], ,[object Object],_1 lastMicOn ,[object Object],Q: Can I create custom EQ curves for room correction?
A: Yes, Tesira provides parametric EQ blocks that can be programmed for room correction. Use room analysis software to determine required corrections, then implement them using TTP commands. For complex corrections, consider using multiple EQ blocks in series or Tesira's graphic EQ blocks for specific frequency shaping.
Control System Integration
Q: What's the best practice for handling TTP connection failures in control systems?
A: Implement a robust connection management strategy:
[object Object],
,[object Object], ,[object Object],(,[object Object],) {
,[object Object], connected = ,[object Object],;
,[object Object], attempts = ,[object Object],;
,[object Object], maxAttempts = ,[object Object],;
,[object Object], (!connected && attempts < maxAttempts) {
,[object Object], {
tcpSocket.,[object Object],(tesira_ip, ,[object Object],);
response = tcpSocket.,[object Object],(,[object Object],);
,[object Object], (response.,[object Object],(,[object Object],)) {
connected = ,[object Object],;
,[object Object],
,[object Object],(sendKeepAlive, ,[object Object],);
}
} ,[object Object], (error) {
attempts++;
,[object Object],(,[object Object],); ,[object Object],
}
}
,[object Object], connected;
}Q: How do I synchronize preset recalls across multiple Tesira devices?
A: For synchronized preset recalls across multiple devices, send commands in rapid succession and implement verification:

,[object Object], set ,[object Object],:,[object Object], ,[object Object],_1 preset ,[object Object],
,[object Object], set ,[object Object],:,[object Object], ,[object Object],_1 preset ,[object Object],

,[object Object], get ,[object Object],:,[object Object], ,[object Object],_1 preset
,[object Object], get ,[object Object],:,[object Object], ,[object Object],_1 presetTroubleshooting and Maintenance
Q: My Tesira device becomes unresponsive to TTP commands after several hours of operation. What could cause this?
A: This typically indicates a session management issue. Common causes include:
- Multiple control systems creating conflicting sessions
- Missing or improper keepalive implementation
- Session allocation without proper deallocation
- Network timeout issues
Solution: Implement proper session lifecycle management with regular keepalives and session monitoring.
Q: How do I determine which version of TTP command syntax to use?
A: TTP command syntax varies slightly between Tesira firmware versions. Always check your device's firmware version first:
[object Object], get ,[object Object],:,[object Object], firmwareVersionThen consult the TTP Command Reference for your specific firmware version. When in doubt, use the SESSION enumerate commands to discover available instances and attributes for your system.
Q: What's the best way to backup and restore Tesira configurations?
A: Use Tesira software's built-in backup features for complete system configurations. For runtime settings and presets, implement TTP-based backup scripts:
[object Object],
,[object Object], ,[object Object], ,[object Object],:,[object Object], configuration ,[object Object],
,[object Object],
,[object Object], (,[object Object], i = ,[object Object],; i <= ,[object Object],; i++) {
,[object Object], get ,[object Object],:,[object Object], ,[object Object],_1 presetConfiguration i
