Line Driver: To achieve the
best possible signal to noise ratio and dynamic range from your amplifier, a line driver can increase the head unit's output voltage up to 24 dB (maximum
is 9.5 volts RMS/13
volts peak). The Matrix has three sets of inputs and three sets of outputs.
Input Gain: The input gains are adjustable up to +24 dB, allowing you to increase the
head unit's line voltage to the top of your amp's input range; up to 9.5 volts
RMS/13 volts peak. The three sets of outputs have individual gain controls.
Output Voltage Indicators:
Each set of outputs has four LEDs to indicate the output voltage; 2 volts, 5
volts, 7.5 volts, and Maximized (9.5 volts).
Balanced Inputs: Using the balanced differential input
circuit cancels noise picked up in the transmission line between the Matrix
and the the source unit. The three sets of inputs
can be individually set to balanced or unbalanced if needed.
Ground Isolation: The power supply ground is switchable, in case of
ground loop noise. The factory position is fully isolated (typically the best
choice), but can be changed to Ground or 200Ω.
Input Linking: The channel
1 and channel 2 outputs can be linked to the channel 3 input, useful if the
source unit has only one or two pair of line outputs.
Subsonic Filter: The subsonic filter on the channel 3
outputs is 18 dB/octave at 33 Hz. If the channel 1 and channel 2 outputs are
linked to the channel 3 input, the subsonic filter is applied to those outputs
as well. The crossover point is governed by a replaceable chip, so it can be
Terminal Block: The
power/ground/remote terminal is removable; the wiring is attached to the block,
then the block is plugged into the Matrix.
