6.3 Function of the external ASR battery power supply
(optional only for the ASR Emitter Exclusive versions)
The ASR Battery Power Supply is housed in massive separate case. The case contains six
batteries, each 6Volts/12Ampere-hours and capacitors for buffering summing up to 400,000

F.
Fuses: 0,5A slow-blow 230V, 1A for 115V (charging transformer), 5A slow (for the batteries)
In Standby the circuits inside the ASR Emitter Exclusive are preheated with +/- 10 Volts.
When charging, the unit is supplied from the charging circuitry. During discharging , the 72VA-
Philbert-Mantelschnitt-transformer is separated from the AC line via relays in both phases.
The battery power supply is switched on the buffering capacitors via Mos Fets.
All operations are controlled by an optical digital logic circuitry to avoid RF distortions.
Function and description of the control Leds

turned OFF (
Pos „Off“
): the batteries are charged. The yellow “ Charge
” Led is shining.
When full , the green Leds
“
Batt+Full
”
and
“
Batt-Full
”
are shining.

turned ON (
Pos “Stby”
): the unit is supplied with current out of the charging transformer,
and the batteries are still charged. The red “ Standby
” and “
10 V
” Leds are shining.

turned ON ( Pos 1 or 2 ): the main unit is supplied with current out of the external battery
power supply. The yellow led “ Amp ON
” and the
blue Led “ Line Off
” is shining.
The charging transformer is separated from the AC power line. After that the green
Led “
Batt On
” and two
blue Leds “ Batt+On
” and “
Bat-On
” are shining.

during „
Batt ON
“-mode: the voltage is constantly
monitored . When the voltage is lower than
17 Volts the batteries are empty, and the “
Batt Full
” Leds go away. The Battery PSU switches
into the charging mode- in this mode the main unit is supplied out of the charging transformer.

Also during charging the batteries the Emitter is working and you can still listen to music.

when the batteries are fully charged at 19,5 Volts, the charging transformer will be turned
Off, and the ASR Emitter Exclusive is supplied out of the batteries .

fully charged, the batteries can supply the ASR Emitter for approximately 100 hours .
To lengthen the lifetime of the batteries please turn the Emitter to the „Standby” position for
one night after approximately 2 days of playing in “1 or 2” position. In this case the batteries
are not so much discharged. Lower quantity of discharging is good for the battery life.
One hour of charging is equivalent to about three hours of playing music.
The ASR Battery Power Supply should not be disconnected from the AC outlet for more than
3 weeks, other wise the batteries may be damaged by the self discharging of the batteries.
