HCP 2 MX  marine amplifier feature a compact design ready to face the open water environment, providing tons of clean power. The HCP M heat sink has been crafted from extruded aluminium, a material unmatched for lightness, robustness and heat dissipation. To keep size to a minimum, the power transistors are placed between the PCB and the top side of the heat sink where heat is gathered. Built up heat is then directed to the special dissipation “wings” along the side of the amplifier. Both Pre-In and Speaker-In inputs feature a special balanced circuitry, ensuring high rejection against electro-magnetic interferences for noise-free results. The HCP M amplifiers crossover section ensure extreme flexibility: fully adjustable Lo-pass, Hi-pass filters with 12 dB/Oct. and 24 dB/Oct. slopes according to the amplifier model; Bass Boost is also available to enhance low frequencies. More specifically HCP 2 MX features Hi-Pass pre-amplified outputs, providing the ability to create a Band-Pass on the front woofer.

Overview: The Audison SR 4.500 4-channel amplifier features Audison D-Class Technology (ADT) to deliver high-end performance and efficiency. It features a heavy-duty aluminum chassis in a compact size that's ideal for installation in tight spaces. CEA-2006-A Power Output: The SR 4.500 is compliant with the CEA-2006-A Amplifier Power Standard, which makes it easy for consumers to compare amplifier power specs from one brand to another. The amplifier's CEA-2006-A ratings include: RMS Power (4Ω, 1% THD+N, 14.4 volts): 125 watts x 4 S/N Ratio (ref. 1W output): 83 dBA Additional Power Output Specs: The following additional power output specs are taken @ 14.4 VDC, 1% THD: 4 Channel: 130 watts x 4 (4Ω) 4 Channel: 220 watts x 4 (2Ω) 3 Channel: 120 watts x 2 (4Ω) + 480 watts x 1 (4Ω) 3 Channel: 220 watts x 2 (2Ω) + 440 watts x 1 (4Ω) 2 Channel: 450 watts x 2 (4Ω) Auto Remote Turn-On (ART): The SR 4.500 features ART (Auto Remote Turn-On) which automatically powers on and off the amplifier when an audio signal (or lack of one) is detected on the speaker-level inputs. This is especially helpful when connecting the amplifier to an OEM radio. It eliminates the need for running a remote lead from the head unit to the amp. ART is only available with Speaker Level inputs. Universal Speakers Simulator (USS): The SR 4.500 features Universal Speakers Simulator (USS) technology built into it. USS is a dynamic load circuit that presents a speaker channel with impedance low enough to keep an OEM head unit/amplifier from muting its output, but not low enough to cause over-current or heating problems. This makes the SR 4.500 amplifier ideal for OEM integration. All Channels Driven: Incorporating Audison's "All Channels Driven" design philosophy, the SR 4.500's power supply is designed to handle the cumulative power demand of the amplifier, meaning the amp can deliver the rated power on all channels simultaneously. Optional VCR-S2 Remote Control: The Audison 4-channel amplifier can be used with the optional Audison VCR-S2 Remote Volume Control (sold separately). This lets you adjust the level of the amplifier's B Channel outputs from the front of your vehicle. The rotary control has a point at 0 dB to mark the normal amp output. From there, you can turn the amplifier up to +6dB or attenuate the volume down to -20dB. The VCR-S2's 16' connection cable plugs into a 2-pin socket on the amplifier. Amplifier Controls: The Audison SR 4.500 has a full array of filters and controls to help you configure your audio system for maximum performance. The controls are protected by a removable cover and include the following: Common Controls: Two sets of common controls are provided for the A and B channel sets: Levels (x2): Rotary control let you match the input of the amplifier to the output of your head unit. The amp will accept either line-level or speaker-level inputs. The sensitivity range is 0.2 V (200 mV) to 5 V (line-level) and 800 mV to 20 V (speaker-level). Xover (x2): A and B channel sets each include a 3-way crossover switch for selecting Full, LP, or HP. A corresponding Freq dial lets you select a cutoff frequency from 50 Hz to 3200 Hz. Mono (In L) (x2): A push-button switch lets you run a mono signal to the left input channel (On); Off, lets you run a stereo pair of inputs. ART: A push-button switch lets you activate the Auto Remote Turn-on feature when using speaker-level inputs. ART should be turned Off when using RCA line-level input signals. In B (on/off): A push-button switch determines if the B Channel inputs will be used (on), or if the A Channel inputs will be the input signal for both sets of channels (A&B). Bass Boost: The B Channels include a Bass Boost that can provide up to +12 dB of boost @ 50 Hz. LED Indicators: A Power LED on the top panel will light Blue when the amplifier is powered on and operating normally and Red if the amp over-heats or sees a short-circuit. Connections:  Power/Ground: Set-screw terminals are provided for the power and ground terminals, accepting wire up to 4 AWG (recommended). Note: A 4 AWG amplifier wiring kit with an in-line 50A (or higher) fuse at the battery will be required for installation and is sold separately. Fuses: The SR 4.500 includes two 25A ATO fuse installed on the side of the amp chassis; two spare 25A fuses are included. Remote In/Out: A 6" 2-pin harness provides a 22 AWG Remote In wire for activating the amp when using low-level input signals; a 22 AWG Remote Out can provide a 150 mA trigger output for activating an additional amplifier. Speaker Outputs: Four pairs of set-screw terminals (2 for Ch A/ 2 for Ch B) provide the speaker outputs; terminals can accept wire up to 12 AWG; bridging terminals are identified on the amp. Low-Level (RCA) Inputs: Two sets of stereo RCA inputs (Ch A&B) are provided for connecting an aftermarket head unit to the amplifier; accepts signals ranging from 200 mV-5 V. Speaker-Level Inputs: The SR 4.500 includes two 6" 4-pin speaker-level input harnesses; accepts input signals from a factory headunit ranging from 800 mV-20 V. Pre-Outs: A pair of RCA audio outputs lets you pass RCA input signals out to an additional amplifier.
