CEQ1/1 und CEQ1/1BB
1/1 Precautions
1. Spill no liquids on the equipment and do not drop any objects through openings in
the equipment.
2. Do not place the equipment near any heat sources such as radiators, heating ducts, or ampli­
fiers and do not expose it to direct sunlight, excessive dust, moisture, rain, mechanical vibrations,
or shock.
2. Installation
Installing the CEQ1/1 properly is simple, and
only requires attention to a few issues. The
CEQ1/1 should be used in a grounded metal
rack. The Expansion Out port of the CEQ1/1
should be connected to the Expansion In
port of the next device. Note that if multiple
AM8s are being used with the CEQ1/1, the
CEQ1/1 should be connected to the last AM8
in the chain. Figure 2 shows the correct inter­
connection for CEQ1/1s.
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 unbal­
anced 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 phan­
tom power supplied at all times.
Output connections to the EQ Out connec­
tor can be made balanced or unbalanced.
If an unbalanced connection is desired, sim­
ply 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 par­
allel with the EQ input. If the EQ input is con­
nected unbalanced, the
EQ Thru will also be
unbalanced.
