Frequency Response
±0.5dB, 20Hz-16kHz
Stereo Separation
60dB (typically 65-70dB), 50Hz-15kHz
Noise
Better than 75dB below 100% modulation in baseband and subcarrier;“digital” noise components above 54kHz are –70dB or better.
Distortion
<0.15% THD in baseband and subcarrier at 95% modulation
Crosstalk (M/S or S/M)
-
“Nonlinear” crosstalk is better than –50dB, 50Hz-15kHz
-
“Linear” crosstalk is better than –45dB with pre-emphasis switched off.
Stereo Pilot
19kHz, ±1Hz; level may be adjusted between 6% and 12%, relative to 100% modulation. <1% THD in pilot signal.
Active-balanced, bridging; accept limited program audio levels between –15dBu and +15dBu, corresponding to 100% modulation.
Two unbalanced inputs accommodate SCA or RDS/RBDS subcarriers at levels between –20dBu and 0dBu for nominal 5-10% injection.
Primary Low-Pass Filtering
7-pole, phase-corrected, active-elliptic filter with proprietary
overshoot compensation (defeatable). –60dB or better at 19kHz and above.
Pre-Emphasis
May be jumpered for 75μs or 50μs characteristics; may be defeated by front-panel switch.
Composite Processing
A composite clipper acts on the multiplex signal prior to
injection of the stereo pilot and any auxiliary subcarriers.
Clipping is adjustable between 0dB and 3dB.
Composite Output
Unbalanced output with 75-ohm source impedance. 100%-modulation level is adjustable between 1V p-p and 8V p-p.
Digital Synthesis Sampling Rate
608kHz (16X subcarrier oversampling)
Power Requirement
105-130VAC or 210-255VAC, 50/60Hz; 10W.
Size and Weight
13/4”H x 19”W x 6”D (1U); 7 lbs.
