SPECIFICATIONS
The tuner shall be a frequency synthesized AM and FM
mono radio receiver with all electronic controls. It shall
receive the AM frequency band from 520 to 1,710kHz in
10kHz steps and FM frequency band from 87.9 to
107.9MHz in 200kHz steps. The receiver capability can be
changed, using a power up function, to receive AM
frequencies from 522 to 1,710kHz in 9kHz steps and FM
frequencies from 87.5 to 108.0MHz in 50kHz steps. This
selection shall be independently selectable for each band.
AM sensitivity shall be 26
µ
V and FM sensitivity shall be 3
µ
V.
A scan level switch shall select between low and high
sensitivity for local/distant type reception and be
independently selectable for each band. The nominal
audio output shall be -8dB unbalanced with a noise level at
least -70dB at maximum FM quieting. Inputs shall be
provided for AM loop and 300 ohm FM antennas.
The tuner shall provide four station selection modes: direct
entry, manual scan, automatic scan and automatic memory
entry scan. Station selection can be by station frequency or
memory preset channel and this function along with the first
three selection modes shall be independently selectable for
the AM and FM bands. The fourth automatic memory entry
scan shall scan the selected AM or FM band, starting from
the lowest end of the frequency range and automatically
enter the first 20 stations received into the memory presets.
AM stations shall be so stored in preset channels CH 21 to
CH 40 and FM stations into presets CH 1 to CH 20.
The front panel shall have the following controls BAND
switch to select the AM of FM band and changing reception
frequency ranges; a up/down tuning bar for station
selection; an AUTO/MANUAL tuning selector, a SCAN
LEVEL selector for local or distant sensitivity; a MEMORY
switch for entering a station into memory and for changing
scan modes; a DIRECT IN for selecting manual entry of the
station frequency; a CH/FREQ switch to select between
scanning frequencies and memory presets; ten PRESET
switches for recalling memory presets and entering station
frequencies and a POWER on/off switch. The rear panel
shall have two RCA type jacks wired in parallel for the audio
output and four push-type terminals for connection of the
AM and FM antennas. One AM antenna terminal shall also
connect internal to chassis ground. A 300 ohm twin-lead
dipole and AM loop antennas shall be included.
An optional rack mount kit, the MB-DT920, shall allow
mounting the tuner in a standard 19" E.I.A. equipment rack,
occupying two rack spaces. The tuner shall be enclosed in
a durable, painted, black steel enclosure with a black
anodized, aluminum front panel. AC line voltage shall be
120V, 60Hz. Power consumption shall be 6W. Overall
dimensions shall be 16.54 x 3.27 x 10.63 in. (420 x 83 x
270mm). Weight shall be 6.17lbs. (2.8kg).
The tuner shall be the TOA DT-920.
