when making connections.

• Make connections firmly and correctly. If not, it can cause loss of sound, noise or damage to the amplifier.

ENGLISH

■CONNECTING AUDIO
COMPONENTS

• The TAPE1/MD IN/OUT jacks may also be connected to
the LINE OUT/IN jacks of an additional MD recorder.

• The TAPE2 MONITOR IN/OUT jacks may also be
connected to the LINE OUT/IN jacks of an optional graphic

■CONNECTING SPEAKERS

■AC INPUT CORD

Plug this cord into a wall AC outlet

■SWITCHED AC OUTLET

• This outlet is switched on (power on
mode) and off (standby mode)
according to power control as follows;
(Maximum total capacity is 100 W
(0.43A))

tandby mode - switched AC outlet off

S

ower on mode - switched AC outlet on

P

• This amplifier enables you to listen to two pairs of speakers
individually or in various combinations.
Connect your main speakers to the SPEAKER A terminals and
use the SPEAKER B terminals for the remote pair located
elsewhere in your home.

• Be sure to connect speakers firmly and correctly according to the
channel (left and right) and the polarity (+ and -).

• Do not let the bare speaker wires touch each other or any metal
part of this unit. This could damage this unit and/or the speakers.

• Never touch the speaker terminals while the AC input cord is
connected to the wall AC outlet. Doing so could result in electric
shocks.

■Connecting speaker wire

1. Strip away approx. 10 mm (3/8 inch) of
wire insulation, then twist the wire ends
tight.

2. Loosen by turning the speaker
terminal counter-clockwise.

3. Insert the bare part of the wire.

4. Tighten by turning it clockwise.

Note : For safe amplifier operation, use the speakers with

impedance of over 8Ω when you use either SPEAKER A or
B terminals and use the speakers with impedance of over
16Ω when you use both SPEAKER A and B terminals.

Operations

LISTENING TO A PROGRAM SOURCE

Before operation

ENGLISH

• Enter the standby mode.

• The STANDBY indicator lights up.
This means that the amplifier is not disconnected from
the AC mains and a small amount of current is
retained to support the memorized contents and
operation readiness.

• To switch the power off, push the POWER switch
again, then the power is cut off and the STANDBY
indicator goes off.

1. In the standby mode, turn the power on.

2. Switch the desired speakers on.

or

• Then the corresponding SPEAKER indicator lights up
and the sound can be heard the speakers connected
to "SPEAKER A" or (and) "SPEAKER B" terminals.

• When using headphones for private listening, press
both SPEAKER SELECTOR A and B buttons to
switch the speakers off.

■Note : For safe amplifier operation, be sure to check

impedance of the speakers connected. (Refer
to “CONNECTING SPEAKERS” on page 5)

3. Select the desired input source.

• Each time the POWER button on the remote control is
pressed, the amplifier is turned on to enter the
operating mode or off to enter the standby mode.

• In the standby mode, if the INPUT SELECTOR button
is pressed, the amplifier is turned on automatically and
the desired input is selected.

■SYSTEM POWER ON/OFF

• If the POWER switch of Sherwood component
connected by the DIGI LINK II or III is kept pushed
and its AC input cord is plugged in the switched AC
outlet, each time the amplifier becomes the standby or
the operating mode, its power is turned off or on.

• Under the same conditions, if its AC input cord is not
plugged only in the switched AC outlet, when the
amplifier becomes the standby mode, only its display
is off (meaning that a small amount of current is
retained for operation readiness, etc.)

or

• Then the corresponding indicator lights up.

• When the TAPE 2 MONITOR button is set to on so that the
TAPE 2 MONITOR indicator lights up, other inputs can not
be heard from the speakers.
To listen to an input source other than TAPE 2 MONITOR,
be sure to set the TAPE 2 MONITOR button to off.

■TAPE MONITOR function

You can connect either a tape deck or a graphic
equalizer to the amplifier’s TAPE 2 MONITOR jacks.
Only when you listen to the component connected to
these jacks, set the TAPE 2 MONITOR button to on.
If you connect a 3-head tape deck, you can listen to the
sound being recorded during recording, not the source
sound.
For further details, refer to the operating instructions of
the component connected.
