This eliminates high range frequency and outputs low range frequency. HPF eliminates low range frequency and output high range 4 En <5707000008290>4 Black plate (5, 1) Section Setting the unit !Bass boost level setting applies only to CHANNEL B (channel B) output. 6 Power indicator The power indicator lights up to indicate power ON. Relationship between amplifier gain and head unit output power 02 English Setting gain properly !Protective function included to prevent malfunction of the unit and/or speakers due to excessive output, improper use or improper connection. , this function cuts off the output for a few seconds as a normal function, but output is restored when the volume of the head unit is turned down. A cut in sound output may indicate improper setting of the gain control. To ensure continuous sound output with the head unit at a high volume, set amplifier gain control to a level appropriate for the preout maximum output level of the head unit, so that volume can remain unchanged and to control excess output. Despite correct volume and gain settings, the unit sound still cuts out periodically. in such cases , please contact the nearest authorized Pioneer Service Station. Gain control of this unit Preout level: 2 V (Standard: 500 mV) If amplifier gain is raised improperly, this will simply increase distortion, with little increase in power. Signal waveform when outputting at high volume using amplifier gain control If the signal waveform is distorted due to high output, even if the amplifier gain is raised, the output power will change only slightly. preout level: 4 V Above illustration shows NORMAL gain setting.

Refer to Connections when using the speaker input wire on page 9. Speaker output terminals Please see the following section for speaker connection instructions. Refer to Connections when using the speaker input wire on page 9. System remote control wire (sold separately) Connect male terminal of this wire to the system remote control terminal of the car stereo. The female terminal can be connected to the auto-antenna relay control terminal. If the car stereo lacks a system remote control terminal, connect the male terminal to the power terminal via the ignition switch. [. . . ] If any parts other than those supplied are used, they may damage internal parts of the amplifier, or become loose causing the amplifier to shut down. Do not install in: — Places where it could injure the driver or passengers if the vehicle stops suddenly. € Places where it may interfere with the driver, such as on the floor in front of the driver’s seat. Install tapping screws in such a way that the screw tip does not touch any wire. [. . . ]
