Desktop / Rack-mount Solution
The Flexus FX100 is an all-in-one dual domain audio analyzer for broadcast applications requiring only half of a 19″ rack space. Due to its versatility and excellent specifications, the instrument meets perfectly the typical maintenance or service requirements of radio or TV stations.
Supported measurement functions include e.g. Level, Gain, Distortion, Crosstalk and Phase. These can be executed in the analog domain, with purely digital devices or in cross-domain setups. Thus, the FX100 Analyzer perfectly fits the frequent measurement applications in professional broadcast organizations.
The signal generator of the FX-AES option may be clocked by the internal high-precision oscillator in a range from 28 kHz and 192 kHz. Alternatively, the signal source can be synchronized to a wide range of external clock references such as AES3 house clock, PAL/NTSC video clock or to the AES3 analyzer input sample rate. The analyzer measures the sampling frequency fs at the AES3 inputs and the sync input in parallel.
Interfaces are
- Balanced XLR (AES-EBU)
- Unbalanced BNC (S/PDIF)
- Optical TOSLINK
- Sync Input (BNC)
Handheld Solution
Advantages
- Compact size fitting into every toolbox and OB van
- Dedicated functionality with easy-to-use operation minimizes measurement errors in stressful environments
- Calibrated acoustic, analog and digital measurement system
Applause Meter for Live Sound
The XL2 Sound Level Meter serves as an applause meter for live shows. It measures the actual applause level and displays the results in large font on a connected PC.
Digital Audio Measurements
Testing, monitoring and troubleshooting of digital audio interfaces AES3, S/PDIF, TOS-Link, ADAT, AES 3id (75 Ohm).
Event Logger
Tracks every change of the input signal (carrier, channel status or audio related) and allows long-term monitoring. Possible problems are highlighted automatically.
Audio Monitoring
Plug in to any analog or digital line to hear what is on the line through the built-in speaker. The Automated Gain Control amplifies the signal even if there is only dither on the line.
Digital Delay
Digirator DR2 measures the propagation delay between output and the XLR sync input (which accepts AES3 signals). Results are displayed in seconds and video frames.
Transparency Test
The DR2 tests whether a transmission channel is transparent for nonlinear PCM signals, and indicates if Dolby E, Dolby Digital and/or DTS bit streams can pass.
Synchronization
The DR2 accepts AES3, DARS, Word Clock and Video Black Burst (PAL and NTSC) synchronization signals. The input impedance of the sync input may be switched between 75 or 110 Ohm and High Z.
Occupation of Transmission Lines
The Digirator DR2 generates digital voice sequences, and the Minirator MR-PRO generates analog voice sequences to occupy broadcast lines until they are required for data transmission.
