STA-800D/1000D Equipped Subs
FIG. 3
STA-800D and STA-1000D Connectivity and Panel Operation
Inputs
There are two types of physical input connectors on the STA-800D/
STA1000D; Balanced XLR and single-ended (also referred to as low
level or line level). There are inputs for Left and Right main channels
for both types of connectors. There is also a switch below the input
connectors labeled “Input Level”. This switch can be used to select
either consumer audio (Normal)or pro audio (Hi-Level) voltage levels
depending on the source device.
The input signal(s) can have a High Pass filter applied which
affects the signal that appears on the STA-800D/STA-1000D’s
outputs. The input signal can also have a Delay applied independent
of the High Pass filter which can be used to add delay to the Left
and Right main speakers to accommodate preamps that have no
digital capability. See the next section that discusses the
Integrated Function Controller for a more detailed discussion
on using the High Pass filter and Delay functions.
Input Conguration
Typically for most AVRs and pre/pros that have bass management
capability, connectivity to the STA-800D/STA-1000D would be via
a single balanced or single-ended (RCA) connector from the Subwoofer Pre Out on the AVR or pre/pro to
either the Left or Right amp input (Fig. 4). This assumes the AVR or pre/pro does bass management for the
SAT speakers connected to it, handles the merging of any LFE (.1 channel in multi-chan-nel audio) content with
the bass from the SAT speakers, and manages the proper delay of all speakers and the subwoofer through a
distance or time delay function for each utilized audio channel.
Alternatively, for two-channel preamps that do not have (or do not use) any digital management, the typical
connectivity scenario would be to use both the main channel Left and Right inputs into the STA-800D/STA-
1000D (Fig. 5). In this case the subwoofer would sit between the main L/R outputs of the preamp and the L/R
inputs of the STA-800D/STA1000D, with the L/R outputs of the STA-800D/STA-1000D going to the inputs of the
power amplifier for the system’s L/R main speakers. To then integrate the main speakers and the subwoofer,
the High Pass Filter, Low Pass Filter, and optionally the Delay feature of the STA-800D/STA-1000D amp would
be used. See the following section on the use of the Integrated Function Controller for more information on
using and setting these functions.
