ACCESSORIES • Self-Tapping Screw (M4 × 20) ......................................4 • Hexagon Wrench (Large/Small) ..........................1 SET • Logo Plate ...........................................................................1 INSTALLATION Due to the high power output of the PDR-V75 considerable heat is produced when the amplifier is in operation. For this reason, the amplifier should be mounted in a location which will allow for free circulation of air, such as inside the trunk. For alternate installation locations, please contact your authorized Alpine dealer. 1. Remove the hexagon screws using the supplied Hexagon Wrench (small). (Fig. 1) Hexagon Screws Fig. 1 2. Slide the Top Cover, and lift it to remove. (Fig. 2) • Be sure not to damage the indicator area. Top Cover Fig. 2 3. Using the amplifier as a template, mark the four screw locations. 4. Make sure there are no objects behind the surface that may become damaged during drilling. 5. Drill the screw holes. 6. Position the PDR-V75 over the screw holes, and secure with four self-tapping screws. (Fig. 3) Self-Tapping Screws (M4 × 20) Holes Holes Ground Lead Chassis Fig. 3 NOTE: • To securely connect the ground lead, use an already installed screw on a metal part of the vehicle (marked ( )) or a clean, bare metal spot on the vehicle’s chassis. Be sure this is a good ground by checking continuity to the battery (–) terminal. Connect all equipment to the same ground point while keeping wire length as short as possible. These procedures will help eliminate noise. 3-EN

ATTACHING THE TOP COVER AND LOGO PLATE 1. Attach the Top Cover after connections and confirmation of correct operation. 2. Peel the backing paper from the Logo Plate, then attach it to this unit in your desired direction. (Fig. 4) Logo Plate Backing Paper Fig. 4 4-EN CONNECTIONS * Fig. 5 * Be sure to add an in-line fuse with the battery lead as close as possible to the battery’s positive (+) terminal.

Before making connections, be sure to turn the power off to all audio components. Connect the battery lead from the amp directly to the positive (+) terminal of the vehicle’s battery with appropriate in-line vehicle’s fuse (see Battery Lead section). Do not connect this lead to the vehicle’s fuse block. To prevent external noise from entering the audio system • Locate the unit and route the leads at least 10 cm (4”) away from the vehicle’s harness. • Keep the battery power leads as far away from other leads as possible. • Connect the ground lead securely to a bare metal spot (remove any paint or grease if necessary) of the vehicle’s chassis. • If you add an optional noise suppressor, connect it as far away from the unit as possible. Your Alpine dealer carries various noise suppressors, contact them for further information. • Your Alpine dealer knows best about noise prevention measures so consult your dealer for further information. 5-EN Speaker Output Terminals • The speaker output terminals of this unit are insert terminal. Be sure to observe correct speaker output connections and polarity in relation to the other speakers in the system. Connect the positive output to the positive speaker terminal and the negative to negative. About Subwoofer Input/Output Terminals • The input is stereo but the output is monaural. • Reversing subwoofer polarity may be desirable in some installations for optimum bass performance. About Bridged Connections In the bridged mode, connect the left positive to the positive terminal on the speaker and the right negative to the negative terminal of the speaker. Do not use the speaker (–) terminals as a common lead between the left and right channels. Use a Y-adapter (sold separately) for the input when bridging the outputs. (Refer to the “BRIDGED CONNECTIONS” on page 13.) NOTE: • Do not connect the speaker (–) terminal to the vehicle’s chassis. RCA Input Jacks Connect these jacks to the line out leads on your head unit using RCA extension cables (sold separately). Be sure to observe correct channel connections; Left to Left and Right to Right. Fuse PDR-V75 ...............................................................40 A x 2 USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES. Failure to do so may result in fire or electric shock. Power Supply Terminal Remote Bass Control (Option) Connect the Remote Bass Control Unit (sold separately) to adjust the output level remotely. This is not to replace appropriate gain level setting between the amplifier and head unit. 6-EN Battery Lead (Sold Separately) Be sure to add an in-line fuse with the battery lead as close as possible to the battery’s positive (+) terminal. This fuse will protect your vehicle’s electrical system in case of a short circuit. See below for appropriate fuse value and minimum wire gauge requirement: PDR-V75 ..................... 80 amp fuse, 4 AWG/21 mm2 Ground Lead (Sold Separately) Connect this lead securely to a clean, bare metal spot on the vehicle’s chassis. Verify this point to be a true ground by checking for continuity between that point and the negative (–) terminal of the vehicle’s battery. Ground all your audio components to the same point on the chassis to prevent ground loops while keeping wire length as short as possible. Minimum required wire gauge for this connection is as follows: PDR-V75 ................................................4 AWG/21 mm2 Remote Turn-On Lead (Sold Separately) Connect this lead to the remote turn-on (positive trigger, (+) 12V only) lead of your head unit. If a remote turn-on lead is not available, see “CONNECTION CHECK LIST” section on page 8 for alternative method. NOTE: • When connecting the speaker output leads of the head unit to this unit with an RCA extension cable (sold separately), etc., you do not need to connect the remote turn-on lead, owing to the “REMOTE SENSING” function of this unit. However, the “REMOTE SENSING” function may not work depending on the signal source connected. In such a case, connect the remote turn-on lead to an incoming power supply cord (accessory power) in the ACC position. CAUTION About Power supply wires If the length of the power and ground cables exceed 1 m, or if you connect more than one amplifier, a distribution block should be used. See below for wire gauge recommendations for distribution block connection to battery and ground (depends upon wire length necessary): 2 AWG (33 mm2) or 1/0 AWG (53 mm2) PDR-V75 BATTERY GROUND 1 m 2. Remove the insulation from the ends of the wire leads by about 7 – 10 mm (9/32” – 13/32”). (Fig. 7) Lead end side of the product 7 – 10 mm (9/32” – 13/32”) Fig. 7 NOTES:

(Max.) Distribution block To vehicle’s battery 4 AWG (21 mm2) 2 AWG (33 mm2) or 1/0 AWG (53 mm2) To vehicle’s chassis* Fig. 6 • If length of the exposed wire is too short, a poor connection may occur causing operation failure or sound interruption. • On the other hand, if the length is too long, an electrical short-circuit may occur. 3. Tighten the set screw with the hexagon wrench (included) to secure the lead. (Fig. 8) Before making this connection, use insulated shrink tubing to cover any exposed wire extending beyond the terminal. Hexagon Screw Wire Terminal

* Connect all equipment to the same ground point while keeping wire length as short as possible. Ensure that you install a correctly-rated in-line fuse on the power cable near the battery positive post. Cautions on wire lead connections When using third-party wire cables (power supply wire), use the supplied screws to simplify the connection. Refer to the description below for the proper procedure. If you are in doubt about how to make this connection, consult your dealer. 1. Check the wire size. • Required Wire Size – Battery Lead/Ground Lead ....4 AWG (21 mm2) – Remote Turn-On Lead .............12 AWG (3 mm2) – Speaker Output Lead: SUB W. ............................................. 8 AWG (8 mm2) CH-1/2/3/4 ..................................12 AWG (3 mm2) • If the wire gauge used is unknown, ask your dealer. Wire Fig. 8 NOTES: • Use only the screws included. • For safety reasons, connect the battery leads last. • To prevent disconnection of the leads or dropping of the unit, do not use the cabling to carry the unit. 7-EN CONNECTION CHECK LIST Please check your head unit for the conditions listed below: (Fig. 9) Remote Turn-On Lead a. The head unit does not have a remote turn-on or power antenna lead. b. The head unit’s power antenna lead is activated only when the radio is on (turns off in the tape or CD Mode). c. The head unit’s power antenna lead is logic level output (+) 5V, negative trigger (grounding type), or cannot sustain (+) 12V when connected to other equipment in addition to the vehicle’s power antenna. If any of the above conditions exist, the remote turn-on lead of your PDR-V75 must be connected to a switched power source (ignition) in the vehicle. Be sure to use a 3A fuse as close as possible to this ignition tap. Using this connection method, the PDR-V75 will turn on and stay on as long as the ignition switch is on. If this is objectionable, a SPST (Single Pole, Single Throw) switch, in addition to the 3A fuse mentioned above, may be installed in-line on the PDR-V75 turn-on lead. This switch will then be used to turn on (and off) the PDR-V75. Therefore, the switch should be mounted so that is accessible by the driver. Make sure the switch is turned off when the vehicle is not running. Otherwise, the amplifier will remain on and drain the battery. Blue/White Power Antenna Remote Turn-On Lead To other Alpine component’s Remote Turn-On Leads SPST Switch (optional) Fuse (3A) As close as possible to the vehicle’s ignition tap Ignition Source 8-EN PDR-V75 Fig. 9 SWITCH SETTINGS NOTE: • Before switching each Selector Switch, turn off the power and insert a small screwdriver, etc., perpendicularly to the Switch. Fig. 10 Crossover Mode Selector Switch a) Set to the “OFF” position when the amplifier will be used for driving full range speakers or when using an external electronic crossover. The full frequency bandwidth will be output to the speakers with no high or low frequency attenuation. b) Set to the “ON” position when the amplifier is used to drive a tweeter/ midrange system. The frequencies below the crossover point will be attenuated at 12 dB/octave. NOTE: • In this case the maximum Bass EQ boost level is reduced. Crossover Frequency Adjustment Knob Use this control to adjust the crossover frequency between 50 and 400 Hz. Input Gain Adjustment Control Set the PDR-V75 input gain to the minimum position. Using a dynamic CD as a source, increase the head unit volume until the output distorts. Then, reduce the volume 1 step (or until the output is no longer distorted). Now, increase the amplifier gain until the sound from the speakers becomes distorted. Reduce the gain slightly so the sound is no longer distorted to achieve the optimum gain setting. Input Channel Selector Switch a) This switch setting is for selecting either 2-channel or 4-channel input mode. When set to “1/2”, signal will be copied from CH-1/2 and sent to CH-3/4, eliminating the need for Y-adapters. b) Setting this switch to “3/4” will keep both inputs, CH-1/2 and CH-3/4 independent. A 4-channel source is required for this mode. Subsonic Filter The subsonic filter for cutting ultra low frequencies from the input signal before being amplified. This is desirable for several reasons: – To protect speakers too small or not capable of reproducing ultra low frequencies. – To minimize power wasted from reproducing inaudible sound. – To protect subwoofers in vented enclosures from over excursion below the tuning frequency. 9-EN Bass EQ Adjustment Knob Add a 50 Hz bass boost up to +12 dB to tune your bass response. About Power Indicator Power Indicator Fig. 11 Lights up when power is on. Is off when power is off. Input Channel Selector Switch (SUB W.) a) When this switch is placed in the “1+2+3+4” position, all the signals are mixed and come out from the SUB W. This setting provides signal to the subwoofer channel when only 4 channel input is available. b) Setting this switch to “SUB W.” will send the signal at the inputs of SUB W. (L/R) to SUB W. of the PDR-V75.

Indication color Status Solution Blue Amplifier circuit is normal.

Red (blinking) Operating temperature is high. Decrease the vehicle’s interior temperature to a normal level. The indicator color changes to blue.
