Using this Digi Q is probably going to be the easiest thing to use in your car.
You can control all the functions of this unit from only one knob of the unit.
This one knob can be pressed or rotated to make raise, lower, select and
move from one function to another.
In idol mode, the unit will display the status of your battery voltage. You can
either press the knob to gain access to the functions, or turn the knob in the
dirrection you want to adjust the volume of the system.
ln idol mode oress the knob toswitch between all the functions, like inputs,
EQ settings, volume, sub-control, etc. Once you reach a point you want to
adjust you turn the knob to select your prefered setting.
So what type of controls do you have on this unit, there are master volume
control, fader, sub-woofer crossover and level, 7 EQ bands, input selection
and frequency counter.
This new breed of equalizer has a ton of possibilities. Use your imagination
to set it the best scenario.
With multi inputs, you can select an audio source from all types of devices
With a little work, you can use the AUX/CD CHANGER input to allow you to
listen to almost any portable MP3 Player, or a second CD/DVD player inthe
car.
Using the volume control in the EQ over the volume control of the main
source unit is more practical. Using the main source unit leaves the output
of the EQ at a high tilt which can cause excessive noise or hiss when you
lower the level of the source unit. You can avoid all that by using the volume
of the EQ instead, besides the EQ offers better S/N and seperation than the
source unit (in most cases).
When applying a second source to the EQ, make sure to level match the two,
this way when you switch from one to the other you won’t have unexpected
clip or the need to change the master volume to accomodate the auxilary
source signal. You can do this with the controls in the EQ. you start by press-
ing the knob of the Digi Q until it reaches the control point for the AUX/CD
CHANGER input and make your adjustments accordingly.
