Rosen Entertainment Systems AC3003 Replacing Headphone Batteries, Using Optional Wired Headphones

Rosen Entertainment Systems

REPLACING HEADPHONE BATTERIES

The wireless IR headphones require two AAA batteries. To replace the batteries, slide off the battery compartment door on the right earpiece and insert batteries, as shown. Make certain that the battery polarity matches the marks inside the battery compartment.

USING OPTIONAL WIRED HEADPHONES

There are two jacks for wired headphones on the forward edge of the unit, under a removable cover. When using optional wired headphones, use headphones with a volume control, such as the Rosen AC3004 (the system has no volume adjustment).

ROSEN ENTERTAINMENT SOUND FEATURES

RES Surround-sound.(DVD audio only). While many of us have home theatre systems with center-channel speakers and subwoofers, Rosen knows that most of us don’t have that luxury in our vehicles. So Rosen’s surround-sound circuitry re-creates surround effects when watching movies – especially when using headphones!

RES Sound Processing. (DVD audio only). Movie soundtracks were meant to be heard in a quiet theatre – not in a moving car! The dialogue can be difficult to hear over road noise, and the most dynamic portions of the soundtrack can overpower the car’s sound system.

With RES Sound Processing turned on, dialogue is automatically louder and easier to hear, while loud passages, such as special effects, are automatically lowered slightly. Try RES whether you are listening through the car speakers or wearing headphones, and use it whenever you find it improves the sound.
