Page 5: Quick Introduction To The Es
Important When combining ES 10s with a Stage Accompany Blue Box system, you must take into account that the low-frequency loudspeaker of the Blue Box has an excursion opposite to that of a normal speaker-amplifier combination. The Blue Boxes in combination with the ES 10s have to be switched to inverted phase, or cross cables for ES 10s or Blue Boxes have to be used! •... -

ES 10 USER MANUAL stage accompany 2 Introduction The Stage Accompany ES 10 is a dual channel, high efficiency power amplifier and comprises the following components: • Balanced input stages. Two high efficient amplifiers which deliver each 290 Wrms into 8 Ω, 430 Wrms into 4 Ω... - Page 7 Through the internal EFN circuit, with plug-in modules, extra functions can be added to the amplifier, like cross-over, high- low- or band-pass filtering, equalization and loudspeaker protection. Special protection boards are available for all Stage Accompany loudspeaker systems. The installation of an EFN module needs to be done by an authorised Stage Accompany service centre.

Page 8: Mains Power Connection
Switching between mains voltages has to be done by an authorised Stage Accompany service centre. Connecting to the wrong voltage is dangerous and may damage the amplifier. Always ensure that you use a correctly grounded power supply. - Page 9 ES 10 USER MANUAL stage accompany This will prevent unnecessary power loss in the mains cables. If circumstances do not allow this, it is advisable to connect the adapter block directly to the power supply using a short cable and then connect the individual ES 10s to it using longer leads. Although this method is not ideal, it does limit power loss as much as possible.

This means that you may connect a maximum of two 4 Ω, four 8 Ω, or eight 16 Ω loudspeakers per channel in parallel. Linking the loudspeakers from one enclosure to another has two major disadvantages: 1.The loudspeaker cable from the amplifier to the first enclosure conducts the current for all...
