BOSS Audio Systems CUBE10 Car Subwoofer and Amp Package – Built-in Amplifier, 10 Inch Subwoofer with Passive Radiator, Remote Subwoofer Control

• ...600 Max watt amplifier powers the 10” subwoofer.
• Passive Radiator – A driver unit that has its motor structure (magnet) removed, becomes a passive diaphragm. As a result, there is no Chuffing that you would generally get with a ported box, thus enriching the BASS & making the system more linear.
• Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s).
• High Level Input - Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the CUBE10 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs.
• Phase Control - Phase control lets you adjust the speaker phase with the amplifier if your speakers or subwoofer are hooked up “out of phase”.
• Low Level Input - Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the CUBE10 with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers.
• Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.

LM YN AD8302 Wideband Logarithmic Amplifier Wideband Linear Multiplier Phase Detector Module Low Frequency to 2.7G for OPA695

• ...plications. It requires few external components and a single supply of 2.7 V–5.5 V. The ac-coupled input signals can range from –60 dBm to 0 dBm in a 50 ohm system, from low frequencies up to 2.7 GHz. Both subsystems have an output bandwidth of 30 MHz, which may optionally be reduced by the addition of external filter capacitors. 003cbr003e.
• The AD8302 can be used in controller mode to force the gain and phase of a signal chain toward predetermined setpoints.003cbr003e.
• The AD8302 includes a phase detector of the multiplier type, but with precise phase balance driven by the fully limited signals appearing at the outputs of the two logarithmic amplifiers. Thus, the phase accuracy measurement is independent of signal level over a wide range. The signal inputs are single-ended, allowing them to be matched and connected directly to a directional coupler. Their input impedance is nominally 3 kΩ at low frequencies. 003cbr003e.
• The phase and gain output voltages are simultaneously available at loadable ground referenced outputs over the standard output range of 0 V to 1.8 V. The output drivers can source or sink up to 8 mA. A loadable, stable reference voltage of 1.8 V is available for precise repositioning of the output range by the user.003cbr003e.
