© Low Pass Filter (LPF) Switch
lf this switch is pressed when this amplifier is to be used to drive a
sub-wooter, only sounds in the low-frequency range will be output.
@ Mode Select Switch
Press this switch to use the amplifier as a mono amplifier.
«
When the amplifier is used in this way, the speaker leads need to be con-
nected accordingly.
(See "Connecting Speaker Leads" on page 5.)
@ Load impedance Select Switch
Press this switch when the impedance of the speaker or speakers
cannected to this amplifier is less than 4 ohms.
@ Compulsory Fan Cooling Air inlet
When the volume increases or the inside temperature of the amplifi-
er exceeds about 60°C, the internal cooling fan operates automatical-
ly to take air in through this air inlet and so cool the inside of the
amplifier.
»
There must be enough space in front of and behind the ampfifier for the
cooling to work properly.
@ Power Indicator
The power indicator lights when the power is switched on.
Connecting the (nits

into place.
Test-operate your entire car stereo system to ensure that there are
no faulty wiring
connections between this unit and the rest of
your car stereo system,
The input selector of this amplifier functions automatically. There-
fore, the amplifier may be used with either a car stereo with RCA
pin jacks or a Pioneer car stereo with DIN sockets. For information
about connecting a stereo, see the section entitled "When com-
bined with a car stereo with RCA pin jacks" or that entitled "When
combined with a car stereo with DIN sockets".
When iwo channels (stereo) are used, the speakers should have a
minimum
rating of 200 W or more.
When
a single channel
{mono} is used, the speaker should have a minimum
rating of
400 W or more. lf a speaker whose rating is below that recom
mended is used, the speaker may be damaged. The impedance of
the speakers should be between 2 and 8 ohms.
For detaiied information concerning connections between differ-
ent components and this unit consult their respective instruction
manuals and follow those recommendations precisely.
When wiring connecting leads into place secure them with clarn-
pers and adhesive electrician's tape. Additionally, to prevent any
damage to the insulative coating of the connecting leads, protect
therm with adhesive electrician's tape wherever they may come
into contact with any sharp edges.
Wire all connecting leads so that they stay well clear of high-tem-
perature areas such as the heater exhaust port.
To operate the amplifier and car stereo property, install the contin-
uous power supply lead {orange stripes) and the accessory power
lead (red) correctly.
If the leads are not installed correctly or are
not connected at all, the amplifier and car stereo will not work.
To use a car stereo with DIN sockets, use the optional component
extension cable,
