CONTROL PANEL LAYOUT
1. LINE OUT (RCA) JACKS
RCA style output jacks allow for unfiltered signal to be sent to other amplifiers or processors. Only one Remote
Gain Control can be used when multiple bass amplifiers are connected.
2. LINE IN (RCA) JACKS
The RCA style input jacks are for use with source units that have RCA line level outputs. A source unit with a
minimum of 250mV is required for proper operation. However, this input will accept levels up to 6Vrms.
3. GAIN Control
This control is used to match the input sensitivity of the amplifier to the particular source unit that you are
using.
4. BASS EQ Control
This equalization circuit is used to enhance the low frequency response of the vehicle’s interior. With up to
18dB of boost centered at 45Hz, the BASS EQ can be adjusted to meet your own personal taste.
