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. X-OVER
*Full pass x-over switch
When the switch is in Full position, the full range is bypassed.
* Low Pass x-over switch
INV500DBA - INV1000DBA: The low pass can be adjusted between 50Hz
and 250Hz.
INV559BA - INV669BA: When the switch is in "LPF" position, frequencies
lower than the low pass, frequency setting are passed. The frequency can be
adjusted between 40Hz and 250Hz.
*Band pass select switch
INV559BA - INV669BA: When the switch is in "Band pass" position,
the band Pass range is bypassed.
4. Bass BOOST
INV500DBA - INV1000DBA: The boost can be adjusted between 0dB to18dB.
INV559BA - INV669BA: The boost can be selected among 0dB, 6dB and 12dB.
5. BLUETOOTH
Wireless Bluetooth "ON/OFF"
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.
