DESCRIPTION AND OPERATION 86-6-11
If one headphone amplifier unit has control of the tape player, CD or radio, the other headphone amplifier will be able
to listen and be able to change tape tracks or radio bands. Other buttons allow a search seek function of radio band
or compact disk track, reversal of the tape, radio station and volume adjustment depending on the current operating
mode. If one radio headphone amplifier has control of the radio, tape or CD autochanger the other radio headphone
amplifier is able to change the track or radio band selected. A headphone socket with a glow ring is located on the
control panel. When a headphone is turned on , a 'headphone-module active' signal is sent to the radio cassette
player. The design incorporates panel illumination and a glow-ring to locate the socket in low light conditions. To
control the audio output from the radio headphone amplifiers, signals are sent to and received from the radio cassette
player.
Automatic volume control (High line system only)
An automatic base and treble volume control feature compensates for increases in interior road/transmission noise.
A road speed signal is monitored by the power amplifier, the signal is supplied by the SLABS ECU.

+ BRAKES, DESCRIPTION AND OPERATION, Description.The power amplifier boosts the levels of base
and treble as road speed increases. This system ensures that the apparent volume of sound remains constant and is
not affected by increases in the background noise in the vehicle.
Speakers
Some vehicles will not have all the speakers, the type and location of speakers fitted depends on the trim level and
ICE options specified for the vehicle.
A-post speakers LH/RH (if fitted)
The A-post speakers are located in the A-post trim on each side of the windscreen, and are each protected by a metal
grille. The speakers are held from the rear by a bayonet clip that clamps the speaker on to the A-post trim. The A-post
speakers are a high range type and have a power rating of:
lMid line system A-post speakers have a power rating of 15 watts and an impedance of 4
Ω.
lHigh line system A-post speakers have a power rating of 30 watts and an impedance of 4
Ω.
Upper front and rear door speakers LH/RH (high line system only)
The upper door speakers are located in the upper door trim, the speaker is protected by an integral metal grille. The
speaker is held in by a threaded ring that clamps the speaker from the rear onto the door trim. The upper door speaker
is a mid-range type and has a power rating of 30 watts and an impedance of 4
Ω.
Lower front door speakers LH/RH
The lower front door speaker is located in the front end of the lower (pocket) trim and is secured by three self tapping
screws. The speaker is protected by a clip on circular metal grille. The type of lower front door speakers fitted depends
on trim level and market:
lThe base and mid line systems are fitted with full-range door speakers with a power rating of 15 watts and an
impedance of 4
Ω
lThe high line system is fitted with a low-range door speaker with a power rating of 30 watts and an impedance
of 4
Ω.
Lower rear door speaker LH/RH
The lower rear door speaker is located in the lower door trim and is secured by three self tapping screws. The speaker
is protected by a clip on metal grille. The type of lower rear door speaker fitted depends on trim level and market:
lThe base and mid line systems are fitted with full-range door speakers with a power rating of 15 watts and an
impedance of 4
Ω
lThe high line system is fitted with a low-range door speaker with a power rating of 30 watts and an impedance
of 4
Ω.
Low range tail door speakers (high line system only)
The low range tail door speaker are located in a plastic casing in the lower door trim. Each of the two speakers is
secured to the casing with four self tapping screws. The casing is secured to the lower door structure with eight bolts.
The tail door trim surrounds the casing, the front of the casing is covered by a metal grill that is secured with six
screws. The low range tail door speakers have a power rating of 30 watts and has an impedance of 4
Ω.
