5.LIMITER switch (US-3000 and US-4000 models only)
When the sound source signal is too high, the out- put signal will distort. To prevent this, both channels feature clip limiters to prevent gross distortions on the outputs. It is recommended to avoid clipping but if
it does occur, the clip limiters will greatly reduce the amount of distortion and stress on your speakers and amplifier. It is recommended to keep these switches in the ON position as this will result in better sound and increase the life of your loudspeakers.
NOTE: The
6.BRIDGE / STEREO / PARALLEL switch Use this switch to change the amplifier’s operating mode to STEREO, BRIDGED MONO or PARALLEL MONO. Set this switch to the STEREO position for normal stereo, or
When set to PARALLEL, the input signal connected to channel 1 is routed to both channels. The PARALLEL MONO mode is convenient when running a long
1
mono signal cable to a remote power amplifier(s), and then connecting speakers to both of the channels in order to reproduce the same signal. In PARALLEL mode the input of channel 2 is inactive and should not be used in this configuration.
In the BRIDGED position, the mono input signal con- nected to channel 1 is routed to both the right and left amplifier channels, yet in this mode the speaker is connected between the two channels’ hot outputs and is not referenced to the ground. In this mode the chan- nel 2 input is inactive.
NOTE: See the CONNECTIONS section later in this manual for more details on PARALLEL MONO and BRIDGED MONO modes. WARNING: DO NOT switch to PARALLEL MONO or BRIDGED MONO unless you have read and understood these connections and their limitations as described later in this manual.
7.Binding Post outputs
Use the binding posts to connect your loudspeakers to the amplifier. Binding posts are a good option for fixed installations or when you do not have Speakon- fitted speaker cables. The
