Enclosure Compatibility
Developed by API
®
, the 500 Series format is a widely ac-
cepted standard, and many rack enclosure options are avail-
able from third-party manufacturers; however, their build
and power section design may vary.
The TG12345 MKIV adheres to the 500 Series format stan-
dard, and has no known issues with existing format conform-
ing rack enclosures.
Recommendation:
We recommend using a 500 Series rack
enclosure with an external power supply, such as the API
®
500V with L200 power supply.
Note:
For all BAE racks, we recommend adding a wire from
Earth to power supply common. In many cases, hum can
be avoided and Earth to common is standard procedure on
most electronic equipment.
Power
The TG12345 MKIV is powered by means of a 500 Series
format rack enclosure, purchased separately. The TG12345
MKIV module design adheres to the API
®
500 Series format
current draw specification (+130/-130 mA), and is as fol-
lows:
+16 volts power rail = +105 mA*
-16 volts power rail = -90 mA*
*Maximum current draw as measured when in bypass.
Warning:
Never install or remove a 500 Series module while
the rack enclosure is powered on.
Audio Input & Output Connections
The TG12345 MKIV audio connections are transformer bal-
anced, wired pin 2 hot. Audio input and output connectivity
jacks will be provided by the host 500 Series rack enclosure.
