The following instructions outline the use of Pocket Amp 2. If you are unclear about anything, please let me know by sending an email to Gary@Electric-Avenues.com, I am always happy to help.

Operation Instructions

TYPE OF BATTERIES TO USE - Pocket Amp 2 operates on two rechargeable (1.2 Volt) AA sized batteries.You may use the Nickel Cadmium (Ni-CAD) type, and they will work great. However, it is recomended that Nickel Metal Hydride (NiMH) rechargeable batteries are used if possible. Their higher energy capacity, and lack of memory effect will result in longer operation times. Here is a great page discussing more about the differences.

INSTALLING THE BATTERIES - The batteries should always be installed, even if the amp is used with the AC adapter.To install the batteries, simply remove the two screws located on the back of the amplifier. You will need a small Phillips or "star" screwdriver to do this. Turn the screws counterclockwise to remove them. Remove the amp's lid and install the batteries, observing the polarity. After the batteries are installed, close the amplifier back up, and be careful not to overtighter the screws, just a snug feel is fine.

RECHARGING THE BATTERIES - Once the batteries are installed inside Pocket Amp 2, you will not have to open the amp up for about 500 to 1000 recharging cycles, which should easily amount to three or four years of normal use. Pocket Amp 2 has a built in recharging circuit. When the AC adpater is plugged in, the batteries will automaticaly begin to recharge, whether the amplifier is in the ON or OFF position. If the AC adapter is connected, and the amp is ON and being used, the batteries will not be overcharged. However, if the amplifier is OFF, the AC adapter should not be plugged in for periods longer than eight hours to avoid overcharging.

THE AC ADAPTER - The main purpose of the AC adapter is to recharge the  batteries inside the amplifier, and to power the amp when being used  from an AC source. There are many different AC power systems around the world. If you  ordered an amplifier which did not include the 110 volt AC adapter the  good news is that any adapter with the following features can also be  used: Output Voltage: 3 Volts DC Output Current: 200 Milliamps or greater Plug Size: A 2.5mm male mono plug with a Negative Tip polarity.    A universal adapter such as the one pictured on the right, may also  be used.

USING THE AMPLIFIER - Instead of plugging your headphones directly into the source device, you can now plug your headphones into Pocket Amp 2's output jack (#6). Next, a connection cord is used to feed the audio device's output into Pocket Amp 2's input jack (#5).

Most portable music devices will have a 3.5mm (1/8") "mini" headphone jack. In this case, a 3.5mm (1/8") male-to-male cord (sometimes called a "Patch Cord") is needed for the connection. If your music device has RCA outputs, then an RCA to 3.5mm (1/8") adapter would be needed. After your source device has been connected, It is best to set the volume level on your source device to about 60% of the maximum level, but since each device is different, you may experiment to find the setting you feel is the best. Use the volume knob on Pocket Amp 2 to control the sound level to your headphones.

VOLUME KNOB - The amp's volume knob is not permanently glued on so during shipment (or your own use) it may somehow become stumped down. This can cause the knob to rub against a nut below with friction instead of rotating smoothly. If this happens the knob can be gently pried back up from underneath with the help of a thin coin.
