Line Driver: To achieve the best possible signal to noise ratio
and dynamic range from your amplifiers, 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. Each of the three sets of outputs has an individual
Output Voltage Indicators: Each set of outputs has four LEDs to
indicate the output voltage; 1 volt, 2 volts, 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 Plus 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 rear and subwoofer sections can be linked
(independently) to the front inputs, useful if the source unit has only one or
two pair of line outputs.
Subsonic Filter: The subsonic filter on the subwoofer output
is 18 dB/octave at 33 Hz.
Terminal Block: The power/ground/remote terminal is removable;
the wiring is attached to the block, then the block is plugged into the chassis of
the Matrix Plus.
Optional Wired Remote: An optional wired remote is available
to adjust the subwoofer output level (item number 161ACR1, sold separately).
