Frequently Asked Questions

Q: Which output ports can I connect to the DRA?
A: DRA receivers support PHONO, CD, TAPE-1, TAPE-2, VDP and VCR input ports.
Q: Is there a limit to how many preset stations I can store?
A: 40 preset stations can be stored indefinitely.
Q: Are there any measures I can take to improve reception for AM/FM radio?
A: Ensure that the antenna is firmly secured and signal strength is adequate. Alternatively, purchase an outdoor antenna for improved reception.
Q: Is it Possible to Link Two Speakers to my Receiver?
A: It is Possible to link two pairs of speakers (A and B) with the receiver with the help of a suitable AV receiver.
Q: Is there a specific Ohm value attached to the speakers?
A: Yes, compatible speakers with the AV receivers and amplifiers specify less than 8 ohms.
Q: Are there any Differences in changing Volume and Tone Control? How do I go about it?
A: A rotary knob marked as Volume control can be turned to the left or right to modify the volume level to the desired level where BASS, TREBLE, and BALANCE controls would ensure proper tone setting and equal sound quality.
