Lower 200 Slot; Bus Assignment Module Slot; Series Equalizer Slot; Input Module Slot - API Legacy AXS Operator's Manual

Lower 200 Slot

The lower 200 slot is designed to house additional channel signal processing and is typically fitted with
an API 225 Compressor-Limiter. However, API provides two additional 200 Series signal processing
module options:
215 Sweep Filter
235 Noise Gate/Expander
In the standard configuration, the lower 200 slot signal processor (COMP) is located pre-EQ in the Small
Fader path. The lower 200 slot (COMP) can be moved to the Large Fader path on individual channels by
engaging the COMP LRG button on the 968 Input Module or globally by engaging the COMP LRG button
in the Master Section. Engaging the COMP BYP button in the Master Section will bypass the lower 200
slot (COMP) on all channels.
An internal link inside each 968 Input Module can be programmed to place the lower 200 slot (COMP)
post-EQ instead of pre-EQ in its assigned path.
The signal processor in the lower 200 slot may be accessed using the COMPRESSOR INPUT, SIDE CHAIN,
and COMPRESSOR OUTPUT patch points.
See the 200 Series signal processor descriptions in the "Channel" section later in this manual.

624 Bus Assignment Module Slot

The channel bucket contains dedicated slots designed to support API 624 Bus Assignment Modules. The
624 module handles assignments to Multitrack and Program Buses from the channel Large and Small
Fader paths. It also facilitates pan-pot activation in each path. The assignment module slots can only
be fitted with API 624 Bus Assignment Modules.
Multitrack Bus outputs and access to the program bus signal flow are available in the System patch bay.

500 Series Equalizer Slot

The 500 Series slot on each channel strip is intended to house the channel equalizer (EQ). This 500
Series slot complies with VPR Alliance standards so it can accept any API or VPR approved 500 Series
module except preamps. This slot is not designed to house a preamp and does not have a 48v power
supply for phantom power.
The 500 Series EQ slot is typically fitted with one of four API equalizer or filter modules:
550A 3-Band EQ
550b 4-Band EQ
560 10-Band Graphic EQ
565 Filter Bank
The 500 Series EQ slot is assigned into the Large Fader path by design. The EQ can be routed to the
Small Fader Path by engaging the EQ SM button on the 968 Input Module.

968 Input Module Slot

The channel bucket contains dedicated slots designed to support API 968 Input Modules. The 968 is the
main channel module and contains the Large and Small fader paths, internal channel routing, and
associated controls. The 968 modules also contain the channel auxiliary sends. The input module slots
can only be fitted with API 968 Input Modules.
Access to the channel signal flow is available in the Channel patch bay.

948 Fader Bay

Bays for 948 Fader Modules are located at the bottom of the channel buckets. These bays contain two
8-channel fader modules that support the 16 channels in the bucket.
