AC Power Connection

Your Stage uses an external low-voltage power supply to energize its electrostatic panel. For this reason the proper low-voltage power supply is provided. The power supply should be firmly inserted into the ‘Power In’ receptacle on the rear connection panel of the speaker, then to any convenient AC wall outlet (see figure 1). Your Stage inte- grates a signal sensing circuit which will switch the Stage off after a few minutes of no music signal, and requires less than two seconds to recharge the panel when a music signal is present.

Your Stage speaker is provided with a power supply for the power service supplied in the country of original consumer sale. The AC power rating applicable to a par- ticular unit is specified both on the packing carton and on the power supply.

If you remove your Stage speakers from the country of original sale, be certain that the AC power supplied in any subsequent location is suitable before connecting the low- voltage power supply. Substantially impaired performance or severe damage may occur to a Stage speaker if opera- tion is attempted from an incorrect AC power source.

WARNING! The power supply should not be installed, removed, or left detached from the speaker while connected to an AC power source.

Signal Connection

Use the best speaker cables you can. The length and type of speaker cable used in your system will have an audible effect. Under no circumstance should a wire of gauge higher (thinner) than #16 be used. In general, the lon- ger the length used, the greater the necessity of a lower gauge, and the lower the gauge, the better the sound, with diminishing returns setting in around #8 to #12.

A variety of speaker cables are now available whose manufacturers claim better performance than standard heavy gauge wire. We have verified this in many cases, and the improvements available are often more notice- able than the differences between wires of different gauge. The effects of cables may be masked if the equip- ment is not of the highest quality.

Connections are made at the signal input section on the rear electronics panel of the Stage (see figure 1). Use spade connectors for optimum contact. Make certain that all of your connections are tight.

Be consistent when connecting speaker leads to the ter- minals on the back of the Stage. Take great care to assign the same color to the (+) terminal on both the speaker and the amplifier.

WARNING! Turn your amplifier off before mak- ing or breaking any signal connections!
