The FOUR.1i is an in-dash equalizer with aux inputs. It features a 4+1 band stereo equalizer with ParaBASS. A 13 volt peak preamp line driver provides a smooth performance. The two channel preamp input come built into this equalizer. It has an Independent front, rear and subwoofer out. The 2-way equalizer provides maximum performance. Front and rear panel auxiliary inputs provide adjustability. For more customization, choose between either blue or red illumination. The in-dash equalizer with aux inputs also includes a Master volume control. A Fader also comes standard. Level controls allow the user to find the right amount of customization. The equalizer fits 1/2 din chassis. Left/right input level controls are also included. PWM switching power supply is one of the many features on the in-dash equalizer The unit also Includes mounting brackets. An LED Voltage Indicator always keeps the user included in its current status. The equalizer has 1 Preamp Input. The equalizer has 2 Preamp Outputs. The input Gain is 0-20dB.
