2.4.2 API 500 Series Slot
Input channels 3 & 4 are each equipped with an API 500 series slot that can accept
any module that conforms the standards set forth by the API VPR Alliance. These 500
series slots are built to power and interface any API or JDK Audio 500 series module.
Suggested modules include:
• API 525 Compressor Re-Issue
• API 527 Compressor/Limiter
• API 550A 3-Band EQ
• API 550b 4-Band EQ
• API 560 10-band Graphic EQ
• API 565 Filter Set
• JDK V12 Single Channel Compressor
• JDK V14 4-Band EQ
More information about these 500 series modules can be found at:
http://apiaudio.com and http://www.jdkaudio.com
In addition to API and JDK modules, any third-party module that has been approved
by API as part of the VPR Alliance can be fitted into the slots. Additional information
about approved 500 series modules and the VPR Alliance is available at:
http://apiaudio.com/vpr_alliance.html
IMPORTANT NOTE: Installation of any module that’s not approved by the API VPR
Alliance may void the console warranty!
If the slots remain empty, a jumper is installed in place of a module and the slot is
covered with a blank panel.
API 500 Series Slot Rear Panel Connections
The signal path on channels 3 & 4 can be accessed via the PREAMP OUTPUT and 500
SLOT INPUT jacks on the rear panel.
* The PREAMP OUTPUT and 500 SLOT INPUT jacks work as a “half-normalled” pair and
the channel signal flows through these jacks. If a plug is inserted into the 500 SLOT
INPUT jack, that signal replaces the signal from the PREAMP OUTPUT jack. The signal
from the onboard preamp is broken and does not continue in the channel flow path.
PREAMP OUTPUT: ¼” tip-ring-sleeve, jack*
balanced, low-impedance, line-level
500 SLOT INPUT: ¼” tip-ring-sleeve, switching
jack*, balanced, low-impedance, line-level
