Peavey CS 800X - Channel B Overview and Inputs

tions exist that demand the usage of a TRANSFORMER-BALANCED XLR CONNECTOR
at the input of channel “A”, the (PL-2) transformer must be put here, the selector switch
must be in the “IN” position.
SPEAKER OUTPUTS (9)
Two 1/4" jacks and 5 way binding post speaker output terminals are provided. All these
outputs are in parallel, hence the speaker connection cables can be terminated with 1/4"
phone plugs, banana plugs, or stripped wires for use in the binding post terminals. For
sustained high power applications, the use of the binding post terminals are recommended;
however, care must be exercised to assure correct speaker phasing. Regardless of what
connections are used, the typical parallel speaker load should always be limited to 2 ohms
per channel or 4 ohms BRIDGE mode for any application. Operation at loads of 4 ohms per
channel or 8 ohms BRIDGE mode is more desirable for sustained operation applications due
to the fact that the amplifier will run much cooler at this load. Operation above 4 ohms per
channel, and even open circuit conditions, can always be considered safe; however, sustained
operation at loads below 2 ohms could result in temporary amplifier shut down due to the
thermal limits and/or the internal fault circuitry. When used in BRIDGE mode the positive
speaker lead should be connected to Channel A RED BINDING POST and the negative
speaker lead to Channel B RED BINDING POST.
CHANNELB
NOTE: On this channel a crossover module “ISLAND” has been provided to allow a
PL-MODULE ELECTRONIC CROSSOVER to be used to perform a “BIAMP” function.
Associated with this island are dual crossover input jacks, high and low output jacks, and a
crossover receptacle. These will be discussed further in following sections, but please note
that the channel B patches are somewhat different from those of channel A.
HIGH Z INPUT JACKS (10)
Two parallel input jacks are also provided in this channel, allowing the flexibility of the Y-
cord capability here as well. These jacks are also not chassis grounded and will provide a
QUASI-BALANCED input capability. Both of these input jacks are “switching” type, where
usage of either of these jacks disables the signal feed from the LOW Z INPUT circuitry
associated with this channel. This is necessary to allow this input to be patched from the
appropriate electronic crossover output jack and then use the LOW Z INPUT circuitry as the
input for the electronic crossover. This feature prevents these jacks from being used as
outputs from the LOW Z INPUT circuitry, as was possible with the Channel A input jacks.
LOWZINPUT(ll)
A conventional three-pin, female XLR input jack is also provided here, and it can be used as
the channel B input, provided the HI Z INPUT jacks are not being used. When the (PL-2)
line-balancing transformer is not used, this XLR input becomes QUASI-BALANCED with
the exact same pinout arrangements as discussed for channel A. When the (PL-2) line balanc¬
ing transformer is used, this XLR input becomes fully TRANSFORMER-BALANCED,
again with the same pin polarities as those presented for channel A. (See the PL-2 SELEC¬
TOR SWITCH manual section for details on related settings). The output of this low Z
