Frequently Asked Questions - HDA-V90 ALPINE

What type of vehicle is compatible with the Alpine HDA-V90?

The unit is designed for use on 12 volt negative ground cars. Check with your dealer if you are not certain.

How do I connect the power supply of the HDA-V90?

Connect the battery wire (sold separately) to the positive (+) terminal of the battery via an external 90 A fuse. Ground the ground wire to a clean metal point on the chassis. Connect the remote turn-on lead (REM) to the corresponding output of the head unit or a switched power source (ACC) with a 3 A fuse.

What is the maximum power per channel?

Under 4 Ω at 14.4 V: 75 W RMS x 4 for speaker channels and 300 W RMS x 1 for subwoofer. Under 2 Ω: 100 W RMS x 4 and 500 W RMS x 1. Bridged (4 Ω): 200 W RMS x 2.

How do I adjust the input level (Gain)?

Set the gain to minimum. Increase the head unit volume until sound distorts, then reduce by one step. Increase the amplifier gain until distortion, then reduce slightly for optimal setting.

What does the indicator light mean?

Blue: normal operation. Flashing red: high temperature (lower volume). Steady red: fault (short circuit, overheating or overvoltage). Turn off the unit, correct the problem, then turn on again.

How do I configure the input channels for a 2 or 4 channel system?

Use the INPUT CHANNEL switch (CH-3/4): in position 1/2, the signal is copied from CH-1/2 to CH-3/4 (2 channel mode). In position 3/4, the inputs are independent (4 channel mode). For subwoofer, set the SUBWOOFER switch to 1+2+3+4 (mix) or SUB (dedicated input).

Can I use a speaker-level to RCA converter?

Yes, if your head unit does not have RCA outputs. Then set the INPUT LEVEL switch to HI and connect the speaker wires to the RCA inputs via the adapter cable. The AUTO WAKE function will turn on the amplifier automatically.

How do I perform a bridged (parallel) connection?

For bridging on one channel, connect the positive (+) terminal of the speaker to the positive output of the left channel (e.g., CH-1) and the negative (-) terminal to the negative output of the right channel (CH-2). Do not use the negative terminals of both channels simultaneously. Ensure the total impedance is at least 4 Ω.

Where should I install the amplifier in the vehicle?

Choose a well-ventilated location, such as the trunk, to dissipate heat. Attach the supplied mounting feet, then screw the amplifier. Avoid humid or dusty areas and ensure you do not drill into pipes or cables.

What accessories are needed for remote bass control?

You can connect an optional bass control unit, model RUX-KNOB or RUX-KNOB.2 (sold separately). Plug it into the REMOTE BASS CONTROL jack on the amplifier.

- Reversing subwoofer polarity (swapping positive and negative connections to the subwoofer) 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 of 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.

NOTE:

- Do not connect the speaker (−) terminal to the vehicle's chassis.

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.

- For details on the wires size to be used, refer to the supplied "Cautions on Power Supply Wires Connection" and "Cautions on Power Supply Wires" (page 18), and then use the wire of the specified size.

- If the wire gauge used is unknown, ask your dealer.

1. Remove the insulation from the ends of the wire leads by about 7 - 10 mm (9/32" - 13/32").

7 - 10 mm (9/32" - 13/32") Twist the tip of wire leads Lead end side of the product

NOTES:

• 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.

• Tighten the hexagon hole screw with the hexagon wrench (Large or Small) (included) to secure the lead.

Before making this connection, use insulated shrink tubing to cover any exposed wire extending beyond the terminal.

Battery Connector Battery Lead Hexagon wrench Remote Turn On Lead Ground Lead Hexagon wrench Speaker Connector Speaker Output Lead (+) Speaker Output Lead (-)

NOTES:

• Be sure to use the Hexagon hole screw attached to the Battery Connector or Speaker Connector.
• 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.

CONNECTION CHECK LIST

Please check your head unit for the conditions listed below:

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 HDA-M80/HDA-F60/HDA-V90 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 HDA-M80/HDA-F60/HDA-V90 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 HDA-M80/HDA-F60/HDA-V90 turn-on lead. This switch will then be used to turn on (and off) the HDA-M80/HDA-F60/HDA-V90. 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.

① Subsonic Filter (HDA-M80/HDA-V90 only)

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.

② Crossover Frequency Adjustment Knob (LP FILTER) (HDA-M80/HDA-V90 only)

Use this control to adjust the crossover frequency between 50 to 400 Hz.

③ Bass EQ Adjustment Knob (HDA-M80/HDA-V90 only)

Add a 50 Hz bass boost up to +12 dB to tune your bass response.

④ Input Gain Adjustment Control

Set the HDA-M80/HDA-F60/HDA-V90 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.

⑤ Crossover Mode Selector Switch (HDA-F60 only)

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 "HP" 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.

c) Set to the "LP" position when the amplifier is used to drive a subwoofer. The frequencies above the crossover point will be attenuated at 12 dB/octave.

⑥ Crossover Frequency Adjustment Knob (HDA-F60/HDA-V90 only)

Use this control to adjust the crossover frequency between 50 and 400 Hz.

⑦ Input Channel Selector Switch (CHANNEL-3/4) (HDA-F60/HDA-V90 only)

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.

⑧ Crossover Mode Selector Switch (HDA-V90 only)

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.

⑨ Input Channel Selector Switch (SUBWOOFER) (HDA-V90 only)

a) When this switch is placed in the "1+2+3+4" position, all the signals are mixed and come out from the subwoofer. This setting provides signal to the subwoofer channel when only 4 channel input is available.

b) Setting this switch to "SUB" will send the signal at the inputs of SUB to subwoofer of the HDA-V90.

- Do not mistake the Speaker Output Lead on the head unit side connected to this unit. Front Speaker output (L)/(R) to CH1/CH2, Rear Speaker output (L)/(R) to CH3/CH4

- For the "Speaker Input Level System" setting, connecting the Remote Turn-On Lead is not required due to the "REMOTE SENSING" function of this product. 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.

■ Important Tips on Bridging an Amplifier

Low output will result if only one channel input is used. The Y-adapter is not required if a stereo/mono pair line output is used to drive both inputs of the bridged amp.

■ Cautions on Power Supply Wires

Use the specified wire size according to the total fuse capacity of the amplifier to be installed and the wire length.

For details on the wire size to be used, refer to the supplied "Cautions on Power Supply Wires Connection" and the following connection example.

Connection example when installing an amplifier alone

- When the wire length from the amplifier to the vehicle's battery is 5 m Wire size used for (A): 4 AWG/21 mm ^2

- External Fuse capacity: Make it equal to or larger than the fuse capacity of the amplifier HDA-M80/HDA-V90: equal to or larger than 90 A HDA-F60: equal to or larger than 70 A

    style F fill:#ccc,stroke:#333
    style G fill:#ccc,stroke:#333

Connection example when installing two amplifiers with a fuse capacity of 90 A and one amplifier with 70 A

- When the wire length from each amplifier to the distribution block is 1 m Wire size used for (B): 4 AWG/21 mm ^2 (or 8 AWG/8 mm ^2 )

- When the wire length from the distribution block to the vehicle's battery is 4 m Wire size used for (C): 1/0 AWG/53 mm ^2

- External Fuse capacity: Make it equal to or larger than total fuse capacity of the number of amplifiers installed

90 A + 90 A + 70 A = equal to or larger than 250 A
