AP05mk2

Compact size personal amplifier ideal for use with D.I.Y. speakers.

Features

High sound quality in a compact, card-size housing

The AP05mk2 is a 5W+5W personal amplifier that can easily play D.I.Y. speakers. Further improvements have been made to the popular previous model to achieve a clearer and more balanced sound. A large, easy-to-adjust volume knob is positioned in the center, and combined with the compact, card-sized steel housing, the new design is easy to use.

Eco-friendly design. Equipped with an auto-standby function that automatically reduces power consumption.

The device is equipped with an auto-standby function that conforms to the ErP Directive for Design for Environment Deployment in Europe. When the input to the unit remains at no signal or near signal level, it automatically switches to standby mode and reduces power consumption to 0.5W or less. This function can be turned ON/OFF and the time until the standby mode is activated can be set to either 1 minute or 12 minutes with the dipswitch on the bottom of the unit, depending on the operating environment and application.

Attention

*Do not use any power source other than the AC adapter supplied with the unit.

*Connect a speaker or speaker system with an impedance of 8 to 16 ohms directly to one output of this unit.

*The equipment that can be connected to the output of this unit is a passive speaker unit or speaker system without an amplifier. Do not connect the inputs or outputs of other devices (amplifiers, etc.).

*The auto standby function may not operate properly depending on the output noise level of the playback device connected to the input terminals of this unit.

*The standby mode may operate when the volume on the playback device is being used at a low level (low volume). In this case, raising the volume of the playback device may improve the problem.

Please use the power switch that doubles as the volume volume control of the main unit to turn the power on and off; turning the power on and off with a switch on a power strip or the like to which the AC adapter is connected may damage this product or the connected speakers.

This product is intended for private use by individuals. We do not guarantee the operation and performance of this product for business use or equipment use, and our product warranty regulations do not apply to such use.

*This product complies with the European RoHS Directive.

FAQ

Q
What happens if I connect a speaker outside the compatible speaker impedance range?
A

Please do not do this as it may cause the AP05mk2 to malfunction.

In particular, do not connect a speaker unit with an impedance value lower than the compatible speaker impedance value (8 ohms or lower), as it may cause the AP05mk2 to overheat or catch fire in the worst case.

If a speaker unit with a compatible speaker impedance value or higher (16 ohms or higher) is connected, the volume may be low, sound quality may be degraded, or other symptoms may occur.

Use a speaker unit with a compatible impedance value.

Q
Can I connect a selector to the end of the speaker output terminals to switch between multiple speakers?
A

Do not connect anything other than passive speakers of appropriate impedance to the speaker output terminals!
Connecting speaker switching switches, etc. may cause malfunction.

The black (-) side of the speaker output terminals is not a common left/right circuit.
The black (-) side of the speaker output terminal does not share the same chassis ground.

Connecting the speaker terminals to a selector that switches only the red (+) side, or to a device that shares the same chassis ground with the black (-) side, may cause a malfunction.

When switching connections, please replace the cables.

Also, please do not connect (wire) one speaker to multiple amplifiers.
