UENTLY ASKED QUESTIONS CONTINUED What kind of headphones should I use Use low impedance 35 60 ohms stereo closed or open style depending on personal preference Sony MDR 7505 headphones are recommended for best fidelity Can I drive speakers with the headphone jack It was designed for headphones The preamp will deliver up to half a watt per channel into eight ohms from its internal stereo headphone amp What do the red LED indicators show The Preamp Overload LED shows when the preamp input stage enters soft clipping The Master Level Overload LED shows when the output stage enters soft clipping Although you might see them light up on rare occasions you ll probably never hear the difference Tell me about the Tuner Out function The Tuner Out jacks have a buffer stage and circuitry which isolates both outputs of the tuner from the rest of the circuitry eliminating a common source of noise This circuit will not load down the pickup or any preamp stage The front and rear panel jacks can be used at the same time The Tuner Out can also be used as an effects send What does the Mute button do When engaged the mute function allows the tuner headphone amp and effects send and return to remain on while the power amp send and XLR direct out feed are disabled This way you can practice at home or in between songs on stage without your power amp on and still get a stereo feed to your headphones complete with stereo effects Use
