To start with, these are the last outputs of a Head Unit that were measured. The maximum frequency response at safe listening levels is 18μV with a sensitivity of Usable sensitivity at a mean of 1.0 which amounts to MONO with an S/N ratio of 80dB and STEREO at 75dB. The total distortion that is harmonic in both channels has a deviation of 0.15%. Moving on to general constraints, starting with power supply, the models for Canada and USA operate at 120V while the Europe models operate at 230 Volts. The Asian variants operate with a multiple voltage ranging from 115 to 230V to 60-50 Hz. The power consumption for these devices is at a maximum of 200W, with a maximum density of 9.5 Kg and outer limits of 434mm by 147mm. In case of remote models, the remote control unit operates with two batteries while keeping a 54mm width and a 27.2 mm depth working along with 100 grams of mass. Understanding how these devices work, it comes clear that specifications and design don’t come with boundaries and are only changing to improve efficiency. All of the fore mentioned values came in conjunction with a consistent architecture that these devices are made of.
Frequently Asked Questions
Starting with the first one, the rated output on the front channels approximately measures upto 60W and 90W on a 6Ohm. The rated responses for the rest of the models come around 100 Watts.
Last of the queries shed light on what sort of video connections do the AVR-1601 or 681 have. To our expectations, these devices have a standard of S-Video connections along with a separating brightness and color signals.
Q3: Will you please highlight the power consumption of the device in question?
A3: The power consumption of the AVR-1601/681 device is rated at two hundred watts only.
Q4: What is the tuning frequency range for FM?
A4: The tuning frequency range for FM in the case of USA, Canada and the Asian models is 87.50 MHz to 107.90 MHz while in the European models it is from 87.50 MHz to 108.00 MHz.
Q5: Is it possible to change the power supply voltage?
A5: Yes, it is relatively easy to change the power supply voltage, it has multiple ranges inclusive of AC115/230V, 50/60Hz models for Asia.
Q6: What kind of remote control does the receiver come with?
A6: With the accompanying AVR-1601/681, a remote control unit (RC-875) is offered that uses up two R6P/AA batteries.
