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 possibility of radiated noise entering the system. 2. GAIN Control The level control will match the amplifiers sensitivity to the source units signal voltage. The Operating range is 200mV minimum to 6V maximum. CAUTION: Do not run the amplifier in high volume for long time, otherwise the loudspeakers will be damaged. 3. SUBSONIC HTG157:The frequency can be adjusted between 0Hz and 80Hz. HTG2100D:The frequency can be adjusted between 10Hz and 60Hz. 4. X-OVER * Full pass x-over switch When the switch is in the "Full" position, the full range is bypassed. * Low pass x-over switch When the switch is in the "LPF" position, frequencies lower than the low pass frequency setting are passed. HTG157/HTG237/HTG257/HTG447 : The frequency can be adjusted between 50Hz and 250Hz. * High pass x-over switch When the switch is in the "HPF" position, frequencies higher than the high pass frequency setting are passed. HTG237/HTG257/HTG447 : The frequency is 80Hz. 5. Low pass x-over frequency control This control is used to select the desired low pass x-over frequency. The frequency can be adjusted between 50Hz and 250Hz. 6. Bass BOOST HTG237/HTG257/HTG2100D : The boost can be adjusted between 0dB to12dB. HTG157/HTG447 : The boost can be selected among 0dB, 6dB and 12dB. 7. REMOTE Controls the subwoofer amplifier gain, from a remote location for ease of adjustment during listening. Warning: Do not connect a level control knob from other manufacturers to the Remote Sub Level Control of any amplifier. Even though the connectors fit properly, the control knob and connector pin positions may be different and the amplifier will be damaged. < 8 >
