countries)
Warning: Always disconnect power lead before performing any changes of the set-up.
Otherwise equipment might be damaged.
SETTING-UP OPERATION
Unpack all components including power
cable and DC cable with SubD connectors.
1. Connect the 6m DC cable to the Power In
connector on the rear panel of your
Rack 500 Dual case.
2.
Connect the other end of the 6m DC
cable to the DC output connector of
the Power Supply.
3.
CHECK THE MAINS VOLTAGE SETTING OF
YOUR POWER SUPPLY. It is labelled above
the mains inlet.
7.
Make sure to tighten screws on all
Sub-D connectors.
4.
If the labelling is not compatible to your
mains voltage do NOT connect the PSU
to mains! Please refer to your dealer.
8.
Insert your 500 module(s) in the Rack500
DUAL case. For xing the modules use M3
screws only.
5.
Power-up the case by connecting the PSU to a correctly earthed power outlet with the
included power lead. In case the included power lead is not compatible to your country
use a 3-wire mains cable with IEC320.C13 connector on one end and the appropriate
power plug for your country on the other end.
9.
Check settings of the toggle switches
for 48V on the 4 XLR standard rear panel
10.
The PSU will accept AC 50-60Hz
either 230V +/-8% or 115V +/- 8%.
6.
Always proceed in the order described,
otherwise equipment might be damaged.
11.
• Low Voltage 6m DC cable with Sub-D
connectors
• Plastic bag with mounting screws for 500
series units - 4 countersunk screws M3x6
and 4 countersunk screws M3x8
Note: Case is equipped with M3 threads.
Use M3 screws only (no UNC etc.)
!
Rack 500 Dual must not be operated at ambient temperatures above 35°C and below 5°C

FUNCTIONAL DESCRIPTION
Zähl Rack 500 Dual was primarily designed as a high quality rack for ZÄHL 500 series units,
but it is also a perfect choice to operate high grade 500 series units from other manufacturers.
It consists of a case which accepts two one-slot or one two-slot API 500 series unit(s)
and a remote power supply.
The case is available with different rear panel versions.
The standard 4-XLR panel is fully compatible to the API 500 standard.
A special 8-XLR rear panel provides additional audio I/Os needed for the ZÄHL IM1 INSERT MASTER unit.
It is also compatible to the API 500 standard but does not provide 48V for phantom supply.
The remote power-supply 500-44 is connected to the case with a 6m Sub-D cable.
It is either set-up for 230V or 115V AC 50-60Hz. Check the labelling above the mains inlet!

TYPICAL APPLICATIONS AND BENEFITS
Rack 500 Dual is ideally suited as a desktop unit. Due to its light weight and small size the user
can even take it on his lap while operating it - thus staying relaxed in the “sweet spot” instead
of bending towards equipment mounted in a rack.
The remote PSU concept prevents any inference of mains supply and mains transformer
with audio circuitry.
