SR AMPLIFIERS

A sophisticated design distinguishes the SR amplifiers, a complete line that ranges from 5 channels to monophonic, all featuring the use of the most advanced D Class technology, for exceptional audio performance within compact dimensions.

The Audison SR 4.500 4-channel amplifier with crossover features great power packed into ultra-compact dimensions (130 W x 4 @ 4Ω).As far as the electronic design is concerned, every aesthetic and functional detail of the Audison SR 4.500 has been taken care of, resulting in a compact amplifier made of extruded aluminum with rounded corners, which facilitates the installation of the product in narrow spaces.

  • Elegant and functional design with rounded corners to minimize space, facilitating installation.
  • Built-in USS (Universal Speakers Simulator).
  • Full built-in crossover section.
  • Optional VCR-S1 remote control offers the possibility to adjust the subwoofer level (-20 / + 6 dB) to your musical preference.
  • Balanced high-level inputs for connecting to the OEM head unit speaker output
  • Low-level RCA for after-market speakers.
  • ART (Automatic Remote On/Off) function.
  • Remote IN / OUT socket to allow control of multiple amplifiers.
  • PRE-OUT allows for system expansion.

Thanks to the generous heat sinks on the two short sides of the amplifiers, there is no need for internal cooling fans, which often cause noise and dust accumulation. In keeping with tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any kind of audio system configuration. The controls, protected by a satin-finished aluminium panel, are located on the top panel of the amplifier, so that they can be easily reached from above, even after the product has been installed. When the system includes an Audison bit processor, the filter section can be totally excluded.

About the Audison SR 4.500

From our tech experts at CEN

A 4-channel amplifier from Audison’s SR range, rated at 500w RMS.

Who it suits

Drivers whose speakers have outgrown the head unit. SR is the compact, high-power line for installs where space is short.

Our tech experts advise

Matching matters more than headline watts, and gains want setting with a meter rather than by ear. It also needs a fused feed from the battery on the correct gauge. Installation and tuning are priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions

Q: How do I choose the right amplifier for my speakers or subwoofer?

A: Match the amplifier's RMS output per channel to the RMS handling of your speakers or subwoofer at the same impedance. The Specification tab lists the power figures. If in doubt, contact CEN with your setup and we will recommend a match.

Q: What wiring do I need to install this amplifier?

A: You will need an amplifier wiring kit sized to the amplifier's power draw, typically including power and earth cable, a fuse, RCA leads and a remote wire. CEN stocks complete wiring kits, and the amplifier's fuse rating is the guide to the cable gauge required.

Q: What class of amplifier is this and does it matter?

A: Class D amplifiers are compact and efficient, ideal for subwoofers and modern installs. Class AB designs are traditionally favoured for outright sound quality on mid and high frequencies. The class is listed in the Specification tab where provided.

Q: Will an amplifier work with my factory head unit?

A: Yes, in most cases. If your head unit has no RCA outputs you will need a line output converter to feed the amplifier a clean signal. CEN stocks line output converters and can advise the right one for your vehicle.

Q: Can CEN install this amplifier?

A: Yes. CEN offers professional amplifier installation from our Nottingham premises, including secure mounting, wiring and setup. Contact us to book.
