Inovonics 631 Re-broadcast FM Receiver/ Rebroadcast
Inovonics' Model 631 is our second generation of frequency-agile, digitally tuned receivers for FM translator and other critical off-air reception applications. Featuring menu-driven access of display and function selections, the 631 provides a switchable IF bandwidth to help solve difficult adjacent-signal problems and readouts of signal strength and multipath distortion to aid antenna alignment. Selectable options and alarms may be remotely controlled or monitored, and high-resolution bargraph readouts give accurate indications of incoming RF and MPX/stereo audio levels.
- Easy to set-up and use
- Selectable wide/narrow IF bandwidth
- Composite/MPX and balanced L/R stereo outputs
- LCD Display
- Menu-driven selection of functions and readouts
- High-resolution bargraph displays indicate:
- MPX and audio levels
- Total carrier modulation
- Left/Right audio levels
- Incoming RF
- Multipath distortion
- Carrier-loss and audio-loss alarms
87.5 –108.1MHz in 100kHz steps.
75-ohm, ‘F’ connector (50-ohm option with ‘N’ connector available).
- MONO: 10μV for 60dB S/N
- STEREO: 150μV for 60dB S/N.
- WIDE: –6dB at ±140kHz
- NARROW: –6dB at ±80kHz
DISTORTION (in MPX or L/R audio)
- WIDE: <0.2% THD
- NARROW: <0.6% THD
- WIDE: typ. >40dB
- NARROW: typ. >20dB
Unbalanced, 75-ohm BNC; adjustable between 2V p-p and 6V p-p at ±75kHz carrier deviation.
An internal clipping circuit limits the MPX output to a maximum level equivalent to ±100kHz carrier deviation.
PROGRAM LINE OUTPUTS
Left/Right active-balanced XLR outputs deliver 4dBm at ±75kHz deviation.
Frequency response ±0.5dB, 20Hz–15kHz
de-emphasis set by internal jumpers to 75μs or 50μs.
Composite/MPX and L/R audio muted when incoming RF falls below the user-programmed LOW-SIG level.
AUDIO LOSS ALARM
Responds to loss of either stereo channel; alarm delay is user-programmable between 5 seconds and 4 minutes.
Front-panel LCD indication of low incoming RF or loss of program audio. Open-collector NPN transistor switches enable remote alarm indication via rear-panel terminal strip.
105-130VAC and 210-260VAC; 50/60Hz; 20W.
