DFS (Detachable Face
Security) Alarm Features
This receiver is equipped with a 45 watts x 4 (peak) MOSFET amplifier for low
distortion, high power output. The amplifier is strong enough to power small subwoofers to
moderate volume levels in compact cars and pickups. For higher volume levels from
subwoofers, an optional amplifier may be connected to the provided sets of preamp outputs.
Illumination: The LED backlit multi-color display illuminates the frequency and
CD track/time in white and the mode indicators and the
select buttons guide in green. There is a bright blue EQ curve display in the left hand
portion of the display that shows the frequency response characteristic of each curve
(except the "CUSTOM" curve). The EEQ button illuminates in blue, and all other
buttons are backlit with green illumination.
This feature gives you a 3-Band Parametric EQ with Selectable Q Factor. You may select a
low (40, 80, 100 or 160Hz), mid (200, 500, 1k or 2kHz) and high frequency (3k, 8k, 10k or
12kHz) to boost or cut. The Q factor (slope of the boost or cut) may be selected from one
of the following four options: 2N (narrow/steep), 1N, 1W and 2W (wide/least steep).
Selecting a narrow (steep) Q factor results in frequencies around the center frequency to
be affected less by the boost or cut than they are with a wide Q factor. This feature is
useful for taming frequency response problems caused by the dimensions, materials and
speaker locations of a vehicle. A different "CUSTOM" curve can be set into
memory for each source; the built-in CD player and optional CD changer are considered a
single source, so they would share the same "CUSTOM" EQ curve.
Preset EQ Curves: This
model has "POWERFUL", "NATURAL", "VOCAL",
"CUSTOM", "EQ FLAT" and "SUPER BASS" preset EQ curves. The
"CUSTOM" curve is one that you create and is stored in memory. There's an EQ
curve display in the left hand portion of the display that shows the frequency response
characteristic of each curve (except the "CUSTOM" curve; the displayed curve
does not change with the settings you make to the custom curve).
F.I.E. (Front Image
Enhancer) with Selectable Cutoff Frequency: Enhances the front image by cutting
mid and high range frequencies to the rear speakers (and the preouts), limiting their
output to low range frequencies. You may select a cutoff frequency of 100, 160 or 250Hz.
You can select "Low", "Mid" or "High" for different levels
of loudness compensation.
Preamplified Outputs: In addition to the front and rear preamp outputs,
there is one set of outputs that may be set for "subwoofer" or
"non fading" output. When set to "non fading", the signal is
full range and the output level is user selectable from 0 to 15. When set to
"subwoofer", the outputs are non fading, and they may be set for
normal or reverse phase, 50Hz, 80Hz or 125Hz low-pass output, and you can set
the level from -6 to +6.
Source Level Adjustment
(SLA): This function prevents radical leaps in volume when switching between
sources. To use this function, you compare the volume level of the sources (AM, CD/CD
changer, AUX) to the FM level, then you adjust the sources level to match that heard when
listening to FM. Since the reference level is based on the FM volume, SLA is not possible
Mutes audio when a cellular call is received, then restores the level once the
call is over. To use this feature, you must have a cellular
phone with a muting output that can be connected to the muting input wire of
receiver is equipped with Pioneer's proprietary Supertuner III, which provides excellent
AM and FM performance.
rotary volume control allows for easy volume level adjustment. Normally, the
knob protrudes just slightly from the front of the face plate. To make the knob
easier to turn, it may be made to stick out further from the face; to make the
knob pop out, you simply press and release the knob. When the knob is in the
extended position, pressing the knob inward returns the knob to it's normal,
Dimming: When the illumination

Pioneer CD changer, this unit will display the titles of CD Text encoded
discs that are played in the changer. When playing a CD Text disc on a CD
Text compatible changer, you cannot switch to the Disc Title Input mode. CD
Text disc titles, artist names and track titles longer than 8 characters may
be scrolled once to reveal the entire string of text by holding down the
- CD Sound Quality Adjustment: Using the "COMP"
(compression) and "DBE" (dynamic bass emphasis) functions, you can adjust
the playback quality of the changer. Each function may be set to one of two
levels or off. The "COMP" function compresses the audio signal to eliminate
distortions caused by the imbalances between the loudest and softest sounds
when played at high volumes. The "DBE" function boosts bass frequencies to
give your music a more full sound.
Note: For these functions to work, they must be
supported by the Pioneer CD changer.
(Detachable Face Security) Alarm Features
The DFS Alarm feature is defeatable. For those who do not want to use the
alarm feature at all, no alarm wires need be connected.
The alarm may be triggered by:
- Input from door pin switches
- Sensors (sold separately)
- Failure to put the face on the unit
before the user selectable "Entry Delay Time" (settings range from
0 to 60 seconds in 5 second increments) runs out.
- Failure to insert and turn the
ignition key from "OFF" to "ON" the predetermined number
of times (dependent on whether the starter disable function is set to
"ON" or "OFF" in the alarm menu.
When triggered, the alarm can respond in
- An alternating two tone output can be
sent to the car speakers (this feature is defeatable). The level of output
sent to the speakers is adjustable.
- The alarm can trigger a horn, siren,
or parking lights relay (not included). The alarm output
can be set to send a constant or pulsed output the relay.
- The alarm can trigger a starter kill relay
(not included), so that the vehicle cannot be started. The starter disable
There are four methods of disarming the
- The alarm will disarm when the face
is placed on the unit before the user selectable "Entry Delay
Time" runs out. This method works regardless of whether the starter
disable function is set to "ON" or "OFF" in the alarm
- If the white/orange wire is connected
to the unlock wire of a keyless entry system and the doors are unlocked via
the keyless entry system, the alarm will disarm.
- If the starter disable function is
turned off, the alarm may be disarmed by inserting the key into the ignition
and turning the key from the "off" position to the "on"
before the "Entry Delay Time" runs out.
- If the starter disable function is
turned on, the alarm may be disarmed by inserting the key into the ignition
(within the "Entry Delay Time") then the key is turned from
"OFF" to "ON" five times within one minute.
There are five alarm wires (white/yellow,
brown, white/red, white/orange and blue/brown) hardwired directly to the radio:
- The white/yellow wire is connected to
door pin switch wiring (by selecting the appropriate setting in the alarm
menu, the white/yellow wire will respond to ground output pin switches or
12V output switches).
- The brown wire can be made to send a
constant 12V output to a siren or horn relay (not included) when the alarm
is triggered, or it may be used to send a pulsed 12V output to a relay (not
included) to flash parking lights (constant or pulsed operation selected in
the alarm menu).
- The white/red wire is connected to a
negative output sensor wire (sensor not included). This wire allows the DFS
Alarm to respond to output from single stage shock, glass break, and
- The white/orange wire is provided for
connection to the unlock wire of keyless entry power door lock systems. When
the keyless entry system is used to unlock the doors, the white/orange wire
will receive the unlock output of the keyless entry system and the alarm
will disarm. By selecting the appropriate setting in the alarm menu, the
white/orange wire can be made to respond to ground output or 12v output
keyless entry systems.
- The blue/brown wire is used to
trigger a relay (not included) for starter kill operation. The blue/brown
lead will provide a continuous 12V output while the alarm is sounding and
for 30 minutes after initial trigger (up to 5 consecutive triggers).
At least two relays (item 120E5000) will
be needed to operate all alarm functions. One relay will be needed to sound a
siren, honk the horn, or flash the parking lights. A second relay will be needed
for the alarm's starter kill function.
