• Check placement of the E/90 Energizer/Amplifier and cables. Placement near a
source of 60 Hz noise (such as a power amplifier or some high intensity lamps) may
cause “60 Hz hum”. Relocate E/90 Unit.
• Check sound source components.
• Check the interconnecting cables for a pool connection.
NOTE:
Due to the ESP/950’s low frequency bandwidth, hum not normally
heard from your stereo system may now become apparent.
Sound From Only One Channel
• The Acoustic Level control on the E/90 Energizer/Amplifier is a dual concentric
unit allowing balance adjustment between right and left channels. Turn both
sections of the knob fully counterclockwise to a desired listening level.
• Check the interconnecting cables for a poor connection.
NOTE:
Before checking for a poor connection, turn unit “OFF”.
• Check source components for right and left signals.
How to Care For Your ESP/950 Stereophone
Avoid any foreign materials from entering the earcups of the ESP/950 or the
connector openings of the E/90 Energizer/Amplifier. To avoid potential electrical
shock, do not spate the ESP/950 and E.90 unit in a damp, rainy or moisture-filled
environment.
To clean your unit, turn the E/90 unit “OFF” and disconnect from any power source
(AD or DC). Gently clean the earcushions and surfaces of the ESP/950 and E/90 unit
with a slightly dampened, soft cloth. Allow any moisture to completely evaporate
before re-connecting and operating the system.
Never operate the system if the E/90 unit or ESP/950 earcups have been
disassembled or mechanically tampered with.
