6. DETACHING THE SPEAKER
Step 3. Hold and slide the speaker to insert its speaker
plug into the speaker receptacle.
Note
In this case, force the speaker onto the speaker
receptacle holding the speaker outer frame.
Step 4. Secure the speaker.
Turning the lock screw approximately about
3 counterclockwise turns using a Phillips
screwdriver causes the flap to rise up and stay
upright.
Caution
After speaker installation, be sure to make a
visual check that the flap rises to lock the
speaker completely.

Step 2. Change the input power (impedance) as
needed. (BS-1034 and BS-1034S only)
The input power (impedance) is factory-preset to
10 W (1 kΩ) for 100 V line.
When changing this setting, use a standard
screwdriver to turn the rotary switch on the
speaker's rear panel to the desired position.
Note
Be sure to follow the instructions below. Failure
to do so may cause damage to the speaker as
excessive input power is applied to it.
· Switch off the amplifier's power when changing
the input power.
· Never make 500 Ω connection in a 100V line
system, as excessive input power is applied to
the speaker, possibly resulting in damage.
Step 1. Turn the lock screw approximately 3 clockwise
turns.
The flap lies down and stays laid. (Refer to
"About lock mechanism.")
Step 2. Hold and slide the speaker to unplug it from the
speaker receptacle.
