CONTROL FUNCTIONS
1. RCA Input jacks
These RCA input jacks are for use with source units that have RCA or Line level
outputs. A source unit with a minimum level of 200mV is required for proper
operation. The use of high quality twisted pair cables is recommended to
decrease the passivity of radiated noise entering the system.
2. GAIN Control
The level control will match the ampliers senstity to the source units signal
voltage. The operating range is 200mW minimum to 6W maximum.
CAUTION: Do not run the amplier in high volume for long time.
Otherwise the loudspeakers will be damaged.
3. SUBSONIC
IN139MINV159A: The frequency can be adjusted between 0Hz and 80Hz.
4. X-OVER
*Full pass x-over switch
When the switch is in Full position, the full range is bypassed.
* Low Pass x-over switch
When the switch is in "LPF" position, frequencies lower than the low pass,
frequency setting are passed.
IN139A/INV159A/INV239A/INV259A/INV449A:
The frequency can be adjusted between 50Hz and 250Hz.
*High pass x-over switch
When the switch is in HPF position, frequencies higher than the high pass
frequency setting are passed.
IN239/INV259A/INV449A: The frequency is 80Hz.
5. Bass BOOST
INV239A/INV259A: The boost can be adjusted between 0dB to12dB.
IM139A/INV159A/INV449A: The boost can be selected among 0dB, 6dB
and 12dB.
6. LED
Will illuminate BLUE to indicate the amplier is on and operating normally,
and will be laminated RED if the amplier shuts down due to short circuit DC
oset, or overheating detected by on board protection circuitry.
