lock connectors can be used to make connections here.

SPEAKERS connectors
These are barrier strip type speaker output connectors.
• If using BRIDGE mode, connect the speakers to the “+”
pin of channels A/C/E/G and the “–” pin of channels B/
D/F/H.

of the bottom row of the barrier strip connectors.
e MODE switches
These specify the amplifier’s operation mode for each two
channels.
• STEREO mode
Each channel (A–H) will operate independently.
• BRIDGE mode
The amplifiers will be bridged for pairs of adjacent chan-
nels (A-B, C-D, E-F, G-H), obtaining a high-power out-
put.
• PARALLEL mode
The input signals will be input to the adjacent channels
(A-B, C-D, E-F, G-H) as well.
r GAIN switch
This switches the input sensitivity / gain for all channels
together.
• +4 dBu: Sets the input sensitivity to +4 dBu.
• 26 dB: Sets the gain to 26 dB.
• 32 dB: Sets the gain to 32 dB.
t HPF switch

set to 20 Hz or 55 Hz, the frequency components below that
frequency will be cut by a 12 dB/oct. filter.

necting the screw to an ground or to the chassis of the mixer,
