Have you ever listened to a song and thought "I know when I saw them live there was more bass than there is in my car"? The cause of this is due to a loss in the transfer from the live performance to recording. To restore that original live experience the cbr uses a special technology that rebuilds and conditions that lost bass information.

Unlike competitive products that must have a full range (20Hz to 20kHz) input signal the cbr can achieve restoration with a signal filtered as low as 120Hz. This means that you use a low pass signal from a head unit or other processor device so long as the filter point is 120Hz or higher.

The remote control unit on the cbr provides complete adjustment over the output level of the bass as well as a separate knob that controls the subsonic filter frequency. This is helpful in tuning the cbr to your specific subwoofer system, vehicle and listening preference.

Bass Reconstruction Processors Specifications

Input Connection Type
This is the type of input that the unit accepts.
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Output Connection Type
This is the type of output that the unit accepts.
Maximum Input Voltage
This is the maximum voltage that the processor is able to accept.
8 volts
Maximum Output Voltage
This is the maximum voltage that the processor is able to output.
8 volts
Adjustable Center Frequency
This function allows you to adjust the center frequency of the signal proccessing.
LED Indicators
This refers to any LED illumination present on the unit. This includes Power Indicators, Clipping Indicators, illuminated logo's, etc.
Bass/Gain Remote
If the unit comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Auxiliary Input
This refers to whether or not the unit has an auxiliary input for connecting additional accessories.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Built-in Crossover
A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is normally used with subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, which is normally used with speakers.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
101 dB
Total Harmonic Distortion (THD)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.

Cache CBR Bass Restoration Processor

May 18, 2011

When we bought this I compared it to the Epicenter. The numbers were all within a few specs of the other, and though I hadn't heard too much about Cache, I thought I would give it a try. A year and a half later, I have no regrets! The CBR does what it was designed to....restore bass that may be lackluster or even missing from the recording process. Love the looks of the all business design that Cache employs. Though the Epicenter is a great item, don't get caught up with the flash of it or similar products. Cache makes very well designed audio gear for the automotive environment.
