Inovonics JUSTIN 808 HD Radio Alignment Processor Supply

Description
JUSTIN HD Radio™ Alignment Processor
Overview
NOW SHIPPING! Approved by iBiquity
Inovonics’ JUSTIN 808 maintains time alignment between analog FM and HD1 channels to within 23 microseconds (±1 sample). No more lost words, stuttering, echoes, or level shifts. The entire sync process is 100% automatic, and the JUSTIN’s Web interface features SNMP support and dispatches e-mail and SMS alarm messages.
What are broadcasters saying about the JUSTIN 808?
“This is the kind of thing that will help make HD Radio better for listeners, car dealers, and the industry in general, by eliminating blending problems…” – Paul Shullins, Greater Boston Media.
“The Justin 808 provides the confidence needed that time alignment between the FM and HD signals are as accurate as possible…” – Saul Perez of Emmis’ KWPR in Los Angles.
The JUSTIN 808 continues to do a consistently great job at keeping our HD and analog signals in alignment, even our station that has separate processing for the HD and analog which results in a wider and more rapid drifting of the HD to analog time delay – Sam Caputa, Emmis Communications
Features
- Precise time alignment between analog FM and HD1
-
- Automatic phase correction and RMS gain leveling
-
- Insert in either the FM or HD Radio AES digital feed
-
- Full Web interface for remote control, metering, etc.
-
- SMS email alarms for loss of signal and loss of audio
-
- Extensive data logging with graphic display
-
- Auto failover with relay bypass
-
Specifications
CONNECTIVITY
Receiver Input
- 75-ohm ‘F’ connector. Receiver tunes 87.5 to 107.9MHz in 200kHz steps. An RF input level of 20dBμV or more assures reliable operation.
-
- AES Digital Audio I O:AES3 (XLR) digital audio loop-through; 44.1kHz sampling rate
-
- Network Interface: LAN (RJ45) connection to local network and through user’s router to Internet for full Web Interface remote control and monitoring.
-
PLACEMENT IN AIRCHAIN
In HD Radio AES Audio Feed:
- Placed in line with the AES audio feed to the HD Radio exciter, the JUSTIN 808 will automatically correct diversity delay errors and r.m.s. level errors between the FM and HD1 programs
-
In Analog FM AES Audio Feed:
- Placed in line with the AES audio feed to the analog FM stereo encoder, the JUSTIN 808 is capable of providing the entire diversity delay, if required. It will automatically correct diversity delay errors, but cannot normalize r.m.s. level errors between the two programs.
-
DELAY CORRECTION
Correction Resolution:
- Corrects to ±1 sample (±23 μs)
-
Maximum Delay Error Correction:
- 16 seconds
-
Time Required to Correlate Delay Errors:
- Small delay errors (up to 0.4 seconds) require up to 30 seconds to correlate; delay errors of 10 seconds could require as much as 3.5 minutes.
-
Time Required to Correct Delay Errors:
- Correction rate is user-programmable between 1 and 1000 samples per second (23μs sec to 23ms sec).
-
“Catch-Up” Button Feature:
- A front-panel menu item, also accessible via the Web Interface, permits a manual time alignment quick reset to a previous long-term mean value. This obviates correlation acquisition and brings time alignment close to the required figure.
-
AUDIO LEVEL & PHASE CORRECTION
The JUSTIN 808 offers automatic program phase correction when a phase reversal is sensed between the analog FM and digital HD1 program channels. R.M.S. level correction is also available when the JUSTIN 808 is placed in the AES digital audio feed to the HD Radio exciter.
ALARMS AND LOGGING
Alarm Conditions
1. RSSI (Low RF signal)
2. Audio Loss or Levels Out of Range
- a. AES Loop-Through
-
- b. Off-air FM Audio
