Low Level Input
Choose the correct length and style of RCA interconnects for your needs. The GLADIATOR
range of RCA
’s give you a wide choice to suit your needs. These have multiple layers of
shielding or are a twisted pair variety for better noise rejection (consult your GLADIATOR
dealer if unsure which to purchase).
Be extra careful with your RCA interconnects. Car environments are notorious for poorly
insulated wires. This means that hiss, engine noise, and fan noise can easily be picked up
through RCA cables if run incorrectly. Avoid running your RCA
’S near large wire looms and
electric fans if possible. Run your RCA cables on the opposite side of the vehicle to the
power cable. Be sure to check for correct balance.
Fig.4 Gain Control
Gain Control
On the amplifier, is the LEVEL control, this control allows you to match the input level of the
amplifier to the output level o your head unit. Matching the input can be accomplished in
three simple steps.
1. Turn the LEVEL control on the amplifier to minimum.
2. Turn up the head unit and adjust to 2/3 maximum volume ensuring that the BASS a
nd TREBLE are set to zero.
3. Adjust the LEVEL control until desired volume is achieved without audible distortion.
Remember, the gain control is not a volume control. Ignoring the three steps above may
leave you with damaged speaker and/or a damaged amplifier.
