Bogen Nyquist Networked 4-Channel Power Amplifier (4 x 300W) - Manual (Page 6)

NQ‑A4060‑G2, NQ‑A4120‑G2, NQ‑A4300‑G2
or station.
The amplifier uses balanced line level (up to 2V RMS ) analog audio
inputs. You can use either Phoenix or RCA as the input (but not both
on the same A+B or C+D terminal pair).
Note : If you use the RCA input and experience a ground hum, place
a jumper on the Phoenix balanced Line-In connector from Pin 1
(shield) to Pin 3 (-) pin to remove the hum.
7. Plug the power line cord into the power source.
8. Toggle the Power switch to the On position.
For information about configuring the amplifier for the Nyquist system,
refer to the Nyquist Power Amplifiers Configuration Manual .
NOTICE
The minimum impedance of a Bridged 70V/25V/8Ω High-Impedance
system should not be less than 8Ω. The minimum impedance of a 2CH
25V/8/4Ω system should not be less than 4Ω per channel.
The combined total power of each speaker tap must not exceed 80% of
the rated amplifier power in either Bridged 70V/25V/8Ω mode or 2CH
25V/8/4Ω mode.
Failure to observe minimum speaker impedance will cause the amplifier
to self protect until the speaker configuration is corrected.
Power Ratings
The NQ-A4300 can provide 300 Watts by four channels (A, B, C, and D) into
25V, or 8Ω, or 4Ω loads, or provide 600 Watts Bridged by two channels (A+B
Bridged and/or C+D Bridged) into 70V, or 25V, or 8Ω load configurations.
The NQ-A4120 can provide 120 Watts by four channels (A, B, C, and D) into
25V, or 8Ω, or 4Ω loads, or provide 240 Watts Bridged by two channels (A+B
Bridged and/or C+D Bridged) into 70V, or 25V, or 8Ω load configurations.
The NQ-A4060 can provide 60 Watts by four channels (A, B, C, and D) into
25V, or 8Ω, or 4Ω loads, or provide 120 Watts Bridged by two channels (A+B
Bridged and/or C+D Bridged) into 70V, or 25V, or 8Ω load configurations.
