Power Supply; User´s Manual - Lake People ADDAC F45 Bedienungsanleitung

GENERAL
The LAKE PEOPLE ADDAC F45 is a combined
A/D-D/A converter of highest quality, built into a
single 19" case with one height unit only. It is
available in different versions, distinguished by
the maximum achievable dynamic range.
The A/D section converts a stereophonic ana-
log input signal into a digital output signal of 24
bit width with a dynamic range of 110 or 115 dB
and 48 or 96 kHz maximum sampling rate.
The analog inputs are equipped with electroni-
cally balanced XLR terminals. Input sensitivity
is adjustable by two rotary faders on the front
panel.
Input level is displayed by two 10-segment LED
meters.
The internal sample rate can be switched to
44.1, 48 kHz (and 96 kHz) on the front panel. A
WCLK and an AES/EBU input are provided for
external synchronization.
The three digital outputs are designed to trans-
formerbalanced AES/EBU specifications (XLR)
as well as to S/P-DIF standard (Cinch and opti-
cal TOS-link).
Digital output format can be set to either consu-
mer or professional format by a frontside
switch.
The D/A section converts a digital signal of up
to 24 bit width with a dynamic range of 115 dB
and 108 kHz maximum sample rate into an
analog stereo output signal.
The three digital inputs are designed to trans-
formerbalanced AES/EBU specifications (XLR)
as well as to S/P-DIF standard (Cinch and opti-
cal TOS-link), selectable on the front panel.
LEDs indicate input selection, sample rate, em-
phasis and professional format status.
The analog output terminals are also located on
the rear panel. Signal is available via electroni-
cally balanced XLR connectors. Analog output
level can be calibrated by trimpots and a rotary
fader accessible from the front.
THE CASE
The earthed case is made of 3mm aluminium
and 1.25mm steel sheet and therefore with-
stands even rough operational conditions.
Internal signal ground and case ground are
connected via a high-impedance R/C combina-
tion.

POWER SUPPLY

The unit is connected to mains via a built-in
IEC-CEE socket with an integrated fuse holder,
which is accessible from the outside.
The"POWER"-switch is located on the front
panel.
Power-on status is indicated by the LED next to
the "POWER"-switch.
POWER-UP
After powering the unit, a two second initializing
sequence in run which serves mainly to calibra-
te the A/D converter chip.
During power up the analog and digital outputs
ar muted and the ERROR"-LED of the sync unit
is lit.
THE SYNC UNIT
The sync unit on the right side of the case ser-
ves to generate the different clocks to operate
the A/D converter. The clock source may be in-
ternal or external.
THE EXTERNAL SYNC INPUTS
The external sync inputs are located on the rear
panel and marked to their function.
They accept AES/EBU (sync)-signals respecti-
vely WCLK signals.
