The ASP-OE2 is an advanced 2-channel OEM adaptor that converts speaker level signal to RCA level signal in order to add an aftermarket amplifier to a factory stereo system. The OE2 also provides you the tools to reverse the roll-off of the bass frequencies that so many car makers are building into their sound systems. This is to protect the factory woofer from being over driven and to prevent the factory amp from clipping on the loud bass notes and causing distortion. The ASP-OE2 is designed for superior sound quality, with top end internal parts and Zapco’s custom built high precision pots. With the ASP-OE2, your system will sound every bit as good with the factory head unit as it would with an aftermarket head unit.
Features
- 2-channels in/4-channels out line driver at 9.5 volts RMS, 14 volts peak
- Distribution pre-amp configurable for 2 or 4 channels
- Dash bass remote
- Bass Recovery for factory head unit
Bass Recovery
If you are driving a fairly new car, you’re probably noticed that when you turn up the volume of the system the bass seem to drop out. That’s because the auto makers are actively equalizing your system. They do this to protect the factory speakers from the damage when you crank up the volume. Well, even when you add amplifiers and speakers to the car, that factory head unit will still pull out the bass frequencies when you turn up the volume. One way to avoid the bass loss is to leave the volume range of the head unit low and turn the gains of the amps way up. That way, the head unit does not know how loud the system is. Unfortunately, this does terrible things to the sound. The OE2 can seamlessly put the bass back into the system regardless of the head unit volume control.
Versatility
The ASP-OE2 also gives you 2 sets of outputs so you can run an amp for bass and an amp for mids and highs. Individual gain controls let you balance the bass amp to the mids/highs amp. For bass recovery the ASP-OE2 has a low-Q shelf filter to put the bass back into the signal and a shelf threshold control to set the volume where the filter becomes active. With the ASP-OE2, you can leave the amp gains down and get crystal clear mids and highs and rock-solid bass from the factory head unit at every volume from quiet conversational background to setting-off-the- neighbor’s-alarm, ground pounding loud.
