Digital latency: • 1.5 mS (receiver only - hybrid mode)

 • 3.0 mS (receiver and transmitter in hybrid mode)

 • 3.0 mS (receiver only - analog compatibility mode)

The 3.0 mS latency in analog compatibility mode time aligns the audio from analog and hybrid transmitters when they are used together in a Venue system.

Frequency selection: 256 frequencies in 100 kHz steps per 25.5 MHz frequency block

Channel Spacing: 100 kHz

Dual Block Range: Built in antenna mulitcoupler covers a two block  range.

Pilot tone: 25 to 32 kHz; 5kHz deviation; unique pilot tone frequency for each selected carrier frequency (Hybrid mode)

Deviation: ± 75 kHz (max) (Hybrid mode)

Receiver Type: Triple conversion superheterodyne

Frequency Stability: ±0.001 %

Multicoupler Bandwidth:

Wideband High: 665 - 862 MHz

Wideband Mid: 537 - 768 MHz

Wideband Low: 470 - 691 MHz

Special Block 944: 8 MHz; 944 - 952 MHz

Front End Bandwidth:

VRS Module: 30 MHz @ -3 dB

VRT Module: 11 MHz @ -3 dB

Sensitivity (20 dB Sinad): 0.9 uV

AM Rejection: >60 dB, 2 uV to 1 Volt

 Image and Spurious

Rejection: 85 dB

Third Order Intercept: VRS:+0 dBm, VRT: +6 dBm

Diversity Methods: Switched, ratio and frequency

FM Detector: Digital pulse counting detector @ 300 kHz

Audio Performance (overall system):

Frequency Response: 32 Hz to 20 kHz (+/-1dB), overall system (400 Series mode)

THD: 0.2% (typical) (400 Series mode)

SNR at receiver output (dB) In Hybrid operating mode:

SmartNR                        No limiting                                   w/ Limiting

OFF                                103.5                                           108.5

NORMAL                        107.0                                           111.5

FULL                               108.5                                           113.0

(Note: the dual envelope “soft” limiter provides exceptionally good handling of transients using variable attack and release time constants. The gradual onset of limiting in the design begins below full modulation, which reduces the measured figure for SNR without limiting by 4.5 dB).

Input Dynamic Range: 125 dB (with full transmitter limiting)

Audio Output Level: -15 dBu to +8 dBu, in 1 dB increments

LCD: 122x32 graphical display

Power Requirements: 10 to 18 VDC; 17.2 W max. (1.72 A @ 10 VDC to

 1.05 A @ 18 VDC)

Weight: VRM with 6 VRS modules: 4.28 lbs. (1946 g)

 VRM with 6 VRT modules: 4.45 lbs. (2018 g)

Dimensions: 19”W x 1.75”H x 7.75”D (panel to rear jacks)

 (48.26 cm x 4.45 cm x 19.67 cm)

Note: Some specifications apply only when the receiver is operating in the Digital Hybrid (400 Series) mode.
