CONNECTIONS

Note: Complete all other connections

to the System 741 before you connect

it to power.

CONNECTING THE

SPEAKERS

1. Press open the pair of terminal

tabs marked SPEAKER/R (right)

on the back of the System 741.

2. Insert one speaker’s red wire into

the red (+) terminal and its black

wire into the black (–) terminal and

release the tabs to close the ter-

minals.

3. Repeat Steps 1 and 2 to connect

the other speaker’s wires to the

terminals marked SPEAKER/L

(left).

CONNECTING AN

EXTERNAL AUDIO

SOURCE

You can connect an external audio

source to your System 741, such as a

TV, CD player, or cassette deck, so

you can listen to that source through

the System 741.

Plug the audio source’s left and right

line level audio wires into the AUX L

(left, white) and R(right, red) input

jacks on the back of the System 741.

To operate an external audio source

with the System 741, see “Using an

External Audio Source” on Page 20.

CONNECTING AN

EXTERNAL ANTENNA

Your System 741 has two built-in an-

tennas. The AM antenna is internal,

and the power cord serves as the FM

antenna.

For improved reception, you can at-

tach an external FM or VHF TV anten-

na (not supplied) to the 75-ohm or

300-ohm terminals on the back of the

system.

Note: If you use an outside VHF TV

antenna, you can use a signal splitter

to connect your radio and TV to the

same antenna.

Your local RadioShack store has a

wide selection of antennas, splitters,

and connectors.

CONNECTING POWER

After making all other connections,

plug your system’s AC power cord into

a standard AC outlet.

Caution: Your system’s power cord

has a polarized plug (one blade is wid-

er than the other). If you have difficulty

inserting the plug into the outlet, do

not force it. Turn the plug over and try

again.

Note: If you are not connecting an ex-

ternal antenna, make sure the sys-

tem’s power cord is fully extended.

CONNECTING

HEADPHONES

To listen privately, you can connect a

pair of stereo headphones with a 1/8-

inch plug (not supplied). Your local

RadioShack store has a wide selec-

tion of stereo headphones.

To connect headphones, plug the

headphones into the PHONES jack on

the front panel.

Note: Connecting headphones auto-

matically disconnects the System

741’s speakers.

Listening Safely

To protect your hearing, follow these

guidelines when you use headphones.

• Set the volume to the lowest set-

ting before you begin listening.

After you begin listening, adjust

the volume to a comfortable listen-

ing level.

• Do not listen at extremely high

volume levels. Extended high-vol-

ume listening can lead to perma-

nent hearing loss.

• Once you set the volume, do not

increase it. Over time your ears

adapt to the volume level, so a

volume level that does not cause

discomfort might still damage your

hearing.

quency range.

Slide the control up to boost or down

to reduce the level. The selected fre-

quency range is not changed if you set

the control to the center position (0).

cies in the low bass range (low organ

notes and bass drums). Reduces rum-

ble or other low-frequency noise.
