PE FO MANCE
Frequency response
(system in PROOF mode): Follows standard 75ps pre-emphasis curve
±1dB, 50-1 5,000Hz. 50ps pre-emphasis available on special order.
Noise
(de-emphasized): -70dB below 100% modulation, 50-15, 000Hz maximum.
Total system distortion (PROOF mode, 100% modulation, de-emphasized): Less than
0.15% THD, 50-15, 000Hz (0.07% typical). Less than 0.2% SMPTE Intermodulation Distortion
(6077000Hz; 4:1).

Shape:
Peaking
Range:
0 to +10dB boost
Tuning: 65Hz " Q " : 1.4
CROSSOVERS
Filters:
150Hz low-pass, 420Hz band-pass, 700Hz band-pass, 1.6kHz band-pass, 3.7kHz band ­
pass, 6.2kHz high-pass.
Filter selectivity:
18dB/octave
Filter topology:
Parallel, in "distributed crossover" arrangement (USA Patent #4,412,100).
Static filter combination:
Outputs of all filters combine to yield static frequency response
±0.5dB throughout the range of 50-15,000Hz.
Dynamic filter combination:
Phase interaction between the filters will not cause audible
dips in the frequency response.
SIX- AND LIMITER
Attack time:
Program-controlled, adjusted according to band frequency.
Release time:
Program-controlled, adjusted according to band frequency. Employs delayed
release for distortion reduction.
Total harmonic distortion:
Does not exceed 0.1% for any frequency in each limiter ' s pass ­
band with any degree of gain reduction, provided signa! is below multiband clipper threshold.
Noise:
Better than 85dB below VCA output clipping level for each limiter.
Distortion cancellation:
All clipper-induced distortion in upper two bands cancelled better
than 30dB below 2.2kHz. Additional distortion reduction provided as a function of frequency in
each band.
Available gain reduction (DENSITY at "5", PRESENCE & BRILLIANCE at " 0"): 20dB
Gain control elements: Proprietary Class-A VCAs.
Indicators:
Six G/R (gain reduction) meters, one for each band of the limiter.
INSTALLATION
Power requirements:
The XT2 takes ±15VDC power from the 8100A/1. When the XT2 is in
use, the 8100A/1 requires 115/230VAC ±15%, 50-60HZ, approximately 40VA.
Dimensions: 19.0" (48.3cm) wide, 10.0" (27.4cm) deep, 3.5" (8.9cm, 2 rack units) high.
Operating temperature range: 0-50°C (32-1 22°F)
Humidity:
0-95% RH, non-condensing.
These specifications describe the performance of an 8100A/1 + XT2 System which has been set up according to the
instructions provided in this manual. These specifications supersede identically labelled specifications in the 8100A/1
Operating Manual. The specification in the 8100A/1 Operating Manual applies if a supplementary specification is not
given here. All specifications subject to change without notice.
