Amplifier Considerations

An amplifier should be well and carefully selected. The range of Joan

Bookshelf Speakers' impedance is between 4 to 8 ohms. Thus, the am-

plifier chosen needs to be able to support a 4-ohm load. For an amplifier

with a switch, it is required to set to select a 4-ohm compatible operation

mode. If an amplifier is not selected or setup properly, the amplifier or

the speakers can be damaged.

Amplifiers between 15 to 95 watts per channel can be used with the Joan

Bookshelf Speakers along with good care. In case audible distortion oc-

curs, it is suggested to turn the volume down until the distortion is gone.

Likewise, when there is audible distortion, it is required that the speaker

and amplifier not play for more than a few seconds.

Usage-Specific Recommendations

Bookshelf Speakers

To use the Joan Bookshelf Speakers as bookshelf speakers, the two

speakers need to be at the same hight as different heights of the speak-

ers can result in degrading sounds quality. Try to place the speakers

as close to the ear level as possible no matter the listening area is at a

seated level or standing level.

Stereo Speaker on Stands

Likewise, please make sure that the speakers are positioned at the ear

level of a listener when they are used with speaker stands. Therefore,

speaker stands with a proper height should be used. To calculate the

perfect ear level, measure the height of the listener's ear when seated

in a listening area, then subtract 15 cm. For instance, if the listener's

ear is 100 cm. from the floor when he/she sits, the appropriate height of

speaker stands will be around 85 cm. high.

Desktop Near-field Monitor

In addition, the Joan Bookshelf Speakers can be used as desktop/near-

field monitor speakers e.g., next to the side of a display or mixing con-

sole. However, the Joan Bookshelf Speakers should not be located close

to CRT displays or other magnetic-sensitive equipment since they are

not shielded. In case placing the Joan Bookshelf Speakers at the ear-

level hight is not possible, it is suggested to use Monitor Isolation Pads

to tilt the speakers back or to decouple them from the desk level.
