MODEL S-2300<br />

MODELS S-3300 and 5 3500<br />

MODEL S-2000IV<br />

MODEL S-2000IV AM/FM MONO TUNER<br />

Engineered for the finest reception of AM and FM broadcast.<br />

Features professional zero-center tuning meter to indicate when<br />

the FM circuit Is exactly on frequency. Includes FM lnter-channel<br />

hush muting system which eliminates noise "hash" between<br />

FM channels to facilitate tuning. Both a rear-panel hush sen<br />

sitivity control and a front panel hush defeat switch are provided<br />

for tuning In weak or distant FM stations. Excellent AM recep<br />

tion through 15 kc wide "hl-fl" bandpass. Sharply selective 5 kc<br />

bandpass on front panel for weaker AM broadcasts. Fly-wheel<br />

tuning is easier and faster. Communication type dial spread with<br />

professional calibrations for slide rule accuracy. Sensitivity: FM,<br />

1.8 wV IHF; AM, 2 iiV at 60% modulation for 0.5 V output.<br />

Selectivity: FM, 200 kc at -3 db; AM wide, -0 db at 15 kc;<br />

RACK PANEL MOUNTING<br />

All models of Sherwood tuners ore available mounted on a gray<br />

hammcrtone steel panel for Installation In standard relay racks.<br />

Panel size, 19* w. x3H" h. To order, change suffix S on model<br />

number to R—example: S-2000IVR. Shipping Weight, 3 lbs.<br />

additional to tuner chassis weight for S-2300, S-3300 and S-3500;<br />

4 lbs. for S-2000IV. Add S7.50 to price of model when panel Is<br />

purchased with tuner. The cost of the panel purchased separately<br />

Is $10.50; Shipping Weight, 5 lbs.<br />
