Audio System AD 480<\/strong> is a four-channel car audio amplifier designed to power several channels in a vehicle audio system. At a supply voltage of 14.4 V, the amplifier delivers 4 \u00d7 75 W RMS into a 4-ohm load. With a 2-ohm load, output increases to 4 \u00d7 120 W RMS.<\/p>\n

Four Channels for a Car Audio System<\/h2>\n

Four channels<\/strong> allow one amplifier to power front and rear speakers while maintaining separate amplification for each system channel. This model is suitable for an installation in which every speaker channel requires its own power stage.<\/p>\n

Before making the connections, calculate the load presented to each channel. Take both speaker impedance and the chosen wiring arrangement into account. This helps prevent a combined load that is unsuitable for the amplifier.<\/p>\n

Understanding the Power Ratings<\/h2>\n

All power ratings are specified at a 14.4 V supply voltage<\/strong>. The same output figures should not be expected when the available voltage is lower. This condition is important when comparing the AD 480 with amplifiers measured under different circumstances.<\/p>\n

RMS power<\/strong> is useful when comparing the continuous operating power of the amplifier and connected speakers. The 2 \u00d7 240 W figure represents maximum power rather than RMS power.<\/p>\n

Planning the Load Impedance<\/h2>\n

The lowest specified load impedance<\/strong> is 2 ohms. A lower combined impedance falls outside the stated limit for this model. For example, two 4-ohm speakers connected in parallel to one channel create a 2-ohm load.<\/p>\n

The supplied information does not explain how the minimum impedance limit applies to different wiring configurations. Choose a system layout only after confirming that its intended load is permitted.<\/p>\n

Matching the Signal Level<\/h2>\n

The input sensitivity<\/strong> can be adjusted from 0.2 to 5 V RMS. This range allows the amplifier gain to be matched to the output level of the audio source. The source signal must fall within the stated range.<\/p>\n

Input sensitivity is not an everyday volume control. Begin setup with a low gain setting. Select a high but clean-sounding volume level on the head unit, then gradually raise the gain until the system reaches the required listening level.<\/p>\n

Excessive gain can make audible distortion appear sooner. A setting that is too low may prevent the system from making full use of the available source signal. Assess the final level by listening from the driver\u2019s seat.<\/p>\n

Purpose of the Frequency Filters<\/h2>\n

The low-pass filter<\/strong> is adjustable from 50 to 4,000 Hz. Use it on a channel that should not reproduce higher frequencies. Match its setting to the operating range of the connected low-frequency speaker.<\/p>\n

The high-pass filter<\/strong> is adjustable from 15 to 5,000 Hz. It limits the lowest frequencies sent to the selected speakers. This is useful when those speakers are not designed to reproduce the deepest part of the bass range.<\/p>\n

The band-pass filter<\/strong> covers an adjustment range of 15 to 4,000 Hz. It is intended to restrict the signal to a selected frequency band. This type of filtering is useful when tuning a section of the system that is responsible for a particular frequency range.<\/p>\n

The specified filter slope is 12 dB per octave<\/strong>. Frequencies are therefore attenuated gradually, allowing the operating ranges of adjacent speakers to overlap. Evaluate the final crossover point by listening to music rather than relying only on the position shown on the adjustment scale.<\/p>\n

Bass Adjustment<\/h2>\n

Bass boost<\/strong> is adjustable from 0 to 12 dB. Start from the neutral position and set the filters and overall gain first. Increase the additional correction only if the system genuinely requires it.<\/p>\n

A higher setting raises the bass level, but it does not replace a correctly selected filter. It also cannot substitute for a speaker designed to reproduce the desired frequency range. Judge the adjustment according to the balance of the complete system.<\/p>\n

Frequency Response<\/h2>\n

The amplifier\u2019s specified frequency response<\/strong> extends from 5 Hz to 25,500 Hz. This describes the operating range of the electronics. It does not indicate the actual frequency range that the connected speakers will reproduce.<\/p>\n

The final sound of the system depends on the characteristics of the speakers, filter settings and installation. The amplifier\u2019s wide operating range allows its filtering to be adapted to different sections of the audio system.<\/p>\n

Installation and Final Setup<\/h2>\n

The amplifier weighs 3.80 kg<\/strong>, so it must be secured to a stable mounting surface. Choose a location that keeps the controls accessible and leave space around the housing for heat to dissipate.<\/p>\n

Route power and signal cables separately. This reduces the likelihood of interference from the vehicle\u2019s electrical system. Secure the cables so that they cannot move or rub against sharp surfaces.<\/p>\n

Adjust the controls in this order: filters first, followed by input sensitivity and channel balance, and then bass correction.<\/p>\n

FAQ<\/h2>\n

What type of car audio system is this amplifier intended for?<\/h3>\n

It is intended for a system in which several speaker channels require separate amplification. The load on each channel and the power handling of the speakers must be matched appropriately.<\/p>\n

Can the factory-installed car stereo be connected?<\/h3>\n

The stereo\u2019s output signal must fall within the amplifier\u2019s input sensitivity range. A signal connection method compatible with both devices is also required.<\/p>\n

Can the amplifier power a subwoofer?<\/h3>\n

The low-pass filter can prepare a more suitable signal for a subwoofer. The wiring configuration must remain within the permitted load and must not exceed the capabilities of the speaker.<\/p>\n

Is the 2 \u00d7 240 W rating enough to select a bridged wiring configuration?<\/h3>\n

No. The supplied information does not establish the bridged power output or the permitted load in bridged operation, so this figure alone is not sufficient for choosing such a wiring configuration.<\/p>\n

Which filter setting should I start with?<\/h3>\n

Begin with the frequency recommended by the speaker manufacturer. Then adjust the setting while listening to the transition between adjacent sections of the system.<\/p>\n

When should bass boost be used?<\/h3>\n

Use it only after setting the filters and input sensitivity. Excessive correction can unbalance the system and cause distortion to become apparent sooner.<\/p>\n

Is this model suitable for a home stereo or cinema system?<\/h3>\n

This is a car amplifier whose output is specified at a voltage typical of a vehicle electrical system. It is not a direct replacement for a domestic amplifier.<\/p>\n","protected":false},"excerpt":{"rendered":"
