Lectrosonics EQ1_EQ2 - Manual (Page 4)

INSTALLATION
Installing the EQ1/EQ2 properly is simple, and only requires attention to a few issues. The EQ1/EQ2 should be used
in a grounded metal rack. The Expansion Out port of the EQ1/EQ2 should be connected to the Expansion In port of
the next device. Note that if multiple AM8s are being used with the EQ1/EQ2, the EQ1/EQ2 should be connected to
the last AM8 in the chain. Figure 2 shows the correct interconnection for EQ1/EQ2s.

EQ1
EQ In and Ref Mic In connections should be made with good quality braid or foil shielded twisted pair. The shield
should be used for the ground (Pin 1) connection. If an unbalanced signal is used, the unbalanced signal lead should
be connected to the “+” input terminal, while the unbalanced ground lead should be connected to both the “-” and
ground terminals of the input connector. The reference microphone input has +15V phantom power supplied at all
times.
Output connections to the EQ Out connector can be made balanced or unbalanced. If an unbalanced connection is
desired, simply connect the unbalanced signal lead to the “+” output terminal, and the unbalanced ground lead to the
output ground terminal. Leave the “-” output terminal unconnected. The EQ Thru connector is electrically in parallel
with the EQ input. If the EQ input is connected unbalanced, the EQ Thru will also be unbalanced.
