-Headphone Level: Adjusts the signal level of the Headphone Out.
-Headphone Out: 1/8” Tip-Ring-Sleeve stereo jack for connection to ste-
reo headphones. The use of MONO jacks will permanently damage the
RS81B. Make sure you are using a stereo jack.
-Power Switch: Applies power to the RS81B.
- SIGNAL STRENGTH: This is a general signal strength meter. It is not cali-
brated to a specic level. It will indicate the general strength of a signal
coming into the RS81B. Remote Description:
-BAND: Switch for AM or FM
-Press “ BAND ” to select FM 1,FM 2, or AM frequencies.

POWER INPUT
110-120V 60Hz 45W
220-240V 50Hz 45W
- AC: Three connector IEC power cord. Please connect to a properly
grounded AC outlet.
- Power Select Switch: Selects between 115V (110-120V)/230V (220-
240V) input power. Follow silk screening on unit. This switch MUST be
in the proper setting before the RS81B is turned on. PERMANENT DAM-
AGE CAN BE DONE TO THE RS81B IF THE POWER APPLIED TO THE RS81B
DOES NOT MATCH SWITCH INDICATION.
- FM ANT. 75 Ohm: Connects to the included 75 Ohm FM antenna.
- AM LOOP ANT. 300 Ohm: Connects to the included 300 Ohm AM Loop
antenna.
- RCA OUTPUTS - Line level.
- XLR OUTPUTS - Line level balanced.
- DC 24V: Input for powering the RS81B when main power is not avail-
able. Connect as the silk screen indicates. This must be 24V DC only. Wir-
ing with incorrect polarity or any other voltage than 24V DC will result
in permanent damage to the RS81B and will not be covered under any
warranty.
REAR PANEL DESCRIPTION
Multi path reections:
FM waves, like light waves, travel in a straight direction unless reected
o objects in their path. Because of this, two sets of waves reach your
antenna from the FM station; those that have traveled directly to the
antenna, and those that have been reected o buildings or mountains.
When the antenna receives both kinds of signals, the two interfere with
each other and result in distorted sound and poor separation. This phe-
nomenon is called “multi path reection”. To reduce this problem, select
an antenna with good directivity and place it in the best location with
strong reception.
