Страница: 3 / 55

Installation
To install the Nyquist NQ-A4060-G2 & NQ-A4120-G2 Power Amplifiers:
1. Ensure the POWER switch is in the off position.
2. This product requires a connection to a Mains circuit with a maximum
of a 20A breaker.
3. Connect a Cat-5 type cable into the amplifier’s Ethernet port and ensure
the other end of the cable is correctly connected to your network.
4. Set the Amplifier Mode switch to the desired setting.
This amplifier can be configured for single-channel bridged mode (aka
bridged-tied load) operation for 70V/25V/8Ω applications, or 2-channel
operation for 25V/8Ω/4Ω applications. The Amplifier Mode switch
is used in conjunction with the Bridged Signal routing setting in the
system console.
Bridged Mode is typically used when higher power, single channel
operation with a high impedance loudspeaker load is desired.
A typical use-case would be for 70V or 25V loudspeaker runs,
where the total load is no less than 8Ω.
2-Channel Mode is typically used for 8Ω or 4Ω loudspeakers runs. This
mode allows the two amplifier channels to operate independently.
In Bridged Mode , Line Input 1 is used as input. For 2-Channel Mode
operation, Line Inputs 1 and 2 are used.
5. Connect the loudspeaker wires to the Amplifier Output Terminals,
which are labeled A +/- and B +/-, as appropriate for the desired mode
of operation (see Figures 1 and 2).
NQ-A2060-G2 and NQ-A2120-G2
These networked Audio Power Amplifiers support a full range of
commercial paging, public address applications, and residential audio
applications, regardless of the venue size. Both the NQ-A2060 and the
NQ-A2120 can operate in 2-channel or single channel bridged mode,
depending on the application need.
Each networked audio power amplifier is a half-rack 1RU high enclosure
containing a Class D audio power amplifier, a universal switched-mode
power supply, an RJ45 network jack, a USB port, and pluggable Phoenix
style terminals for loudspeaker and Line-In connections. Optionally, Line-
In can be connected using the available RCA connectors.
