# Performance Specifications

Telos Alliance/Omnia Research and Development is constantly working to improve the quality of our products. Actual specifications are subject to change or improvement without notice.

> [!NOTE]
> **Note:** Discrete I/O measurements were made in Bypass mode. FM composite measurements were made using the Proof preset.

## Analog and Digital Audio I/O

### Frequency Response

- Complies with the standard 50 or 75 microsecond pre-emphasis curve within ± 0.5 dB, 30 Hz to 15 kHz; the analog left/right output and AES/EBU Digital outputs can be configured for flat or pre-emphasized output

### System Latency

- 36 to 50 ms dependent on processing and clipper selection through the FM channel, as measured from the analog inputs through the composite MPX output

- Status bits follow AES-3 Standard.
- 24-bit resolution, software selection of stereo, mono from left, mono from right, or mono from sum.
- Automatically accepts and locks to valid 44.1 / 48 kHz AES-3 signals

### Digital Audio Output

- AES 1 & 2: Relay Bypass equipped, EMI-suppressed XLR-M, mirrored with RJ45 connectors
- AES 3: RJ45 connector
- Standard 110-ohm source impedance
- Status bits follow AES-3 Standard.
- AES Cable Length: 100 meters using CAT6 or Belden 1800B
- 24-bit resolution, software selection of stereo, mono from left, mono from right, or mono from sum.
- Output Sample Rates: 192kHz, 48 kHz, and 44.1 kHz
- Digital Output Level: AES-3 standard for peak-to-peak 2 to 7v at 48 kHz and 192 kHz into a 110 Ohm load. -22.0 to 0.0 dBFS software adjustable
- AES Cable Length: 100 meters using CAT6 or Belden 1800B
- >120 dB S/THD+N

### External Sync Input

- Output sample rate can be synchronized to the signal present on the AES/EBU input, or to an AES3 signal applied to the Ext. Sync input connector.
- PPS and GPS inputs support pulse per second (10MHz) signals for high-precision synchronization.
