OBSOLESCENT.
Video Crispener Non-linear Amplifier used to increase the
subjective crispness of a 62S-line video signal, which has
been band-limited to 3MHz, without increasing its noise
content.
Mains
operated.
CH1/12A.
DD 1969.
DD Spec 11.35. ACO. OBSOLESCENT.
Logarithmic Non-linear Amplifier used in RGB channels of
flying spot colour telecines to correct deficiences in
film dyes. An input signal of 60dB range is processed to
become logarithmic. Direct replacement for Cintel Type
100043 logarithmic amplifier. ISEP chassis lllmm x 2S3mm.
DD 1969. DD Spec 7.173(70). WITHDRAWN.
Voltage Shaping Fader Control Amplifier used in
conjunction with a modified AMl/S08 is EPS/S09. Takes in
a linear 5V ramp and suitably shapes it to provide the
correct fader characteristic. Printed board with 33 way
ISEP plug. OBSOLESCENT.
AM20 PEAK PROGRAMME AMPLIFIERS
Programme Meter Amplifier, similar to ME12/S but without
input transformer and includes small relay for remote
switching to either of 2 sources. ISEP PCB with 25 way
plug, coding positions 3, 7, 9. DD 1968. DD Spec 1.S3.
OBSOLESCENT.
Peak Programme Amplifier similar to
ME12/8. Printed board l27mm
DD Spec 3.S2S. ACO. OBSOLESCENT.
ME12/5 but
x S4mm.
used in
DD 1969.
Programme Meter Amplifier used in EP1/S07.
DD 1966. WITHDRAWN.
CH1/12A.
AM21 INTERMEDIATE FREQUENCY AMPLIFIERS
IF Amplifier and Discriminator used in stereo VHF
re-broadcast and monitoring receivers RCSM/6, RC3M/4.
Replaces UN1/4l and UN1S/l. CH1/26A, Pegs 11, 40.
DD 1967. DD Spec S.127. OBSOLESCENT.
High Level Output IF Amplifier used in EP7/Sll. Accepts
input from C02/S3S, amplifies it by approximately SOdB and
feeds C02/S34 and MN2/Sl0. Vision carrier frequency:
34.2SMHz.
Sound
