The Falcon / The Osprey
INPUT
RCA signal input for left & right channel.
A minimum of 0.2V input signal is required for correct
operation. Using only 1 input will minimize input signal
and ampli er will need to be gained as such.
POWER & PROTECTION INDICATOR
Power LED, blue light shows correct operation,
Protect LED, red light shows general malfunction, faulty
connection or thermal protection.
clip INDICATOR
The LED will light up if signal is clipped. An occastional
ashing light is acceptable, a constant lit diode is not.
GAIN (5V~0.2v)
Adjusts signal input voltage from the input source
to match the ampli ers input stage.
0.2 V ~ 5 V is the operational voltage.
Voltages beyond may cause errors or damage to the
input section.
SUBSONIC
Variable subsonic setting from 10 Hz to 50 Hz.
It is highly recommended to set it according to the tuning
of your subwoofer enclosure to avoid unnecessary strain to
your sound system.
bass boost
Level control of 0~9 dB @ 45 Hz.
Remote level control port
Connection of external signal level control with clip
indicator. Caution, it is not a volume knob and shall be
adjusted in accordance with the ampli ers gain.
LPF (LOW PASS FILTER 20 Hz ~200 Hz, 24 dB/oct)
Adjusts the cut o point for the low pass crossover
at the frequency chosen.
Phase
Variable phase adjustment from 0 ~ 180
master / slave / slave 2
Master & slave settings enables strapping of the ampli er
with another identical ampli er to achieve twice the power.
When set in master, this unit will be sending the
signal to the slave unit, that will have the switch set to
input slave with the rca connected to the input.
Slave 2 setting will work as a daisy chain of subsequent
ampli ers. Here each ampli er will work independently,
but the signal input will be taken from the master ampli er's
output making gain matching easier.
Gain slave 2
In daisy chain mode or by gain matching, voltage could
eventually di er a few tenths. The slave 2 gain provides
ne tuning of the gain signal from the master amp's output.
avd
Connection for external voltage display showing the true
input voltage for the ampli er.
