XL-1005 Board
The XL-1005 board contains an input 2-channel XLR-type 3-pin analog audio input connector (CN2202). Audio signal
that are input to this board are input to the input/output analog audio signal processor IC (IC3301) on the HN-1004
board.
The XL-1005 board also contains a boost DC-DC converter block for +48 V superimposition.

HN-1004 Board
The HN-1004 board contains an input/output analog audio signal processor IC (IC3301) and an audio control 8-bit
microcomputer (IC3304).
The received input analog audio signals received under control from the microcomputer (IC3300) according to the
settings of the audio control switch block (AU91000) are processed (gain control, etc.) in IC3301. Then the processed
signals are output through the 18-pin connector (CN3301) to the multi-interface shoe connector. The HN-1004 board
also contains a circuit to generate voltages +4.6 V, +6 V, +10 V, and -10 V used in the handle block.
The 2nd zoom lever signal, 2nd SS button (GZ92000) signal, and 2nd zoom lever speed change switch (S0701) signal
received from the HS-1003 board are also output through the 18-pin connector (CN3301) on the HN-1004 board to the
multi-interface shoe connector.

HS-1003 Board
The HS-1003 board finally receives the 2nd zoom lever signal and the 2nd SS button (GZ92000) signal. This board also
contains a 2nd zoom lever speed change switch (S0701). These signals are sent through the 6-pin connector (CN0701)
to the 6-pin connector (CN3304) on the HN-1004 board.
