OPERATING INSTRUCTIONS

THE Stagg SPA-SUB sets are active sets, which means they have all necessary power amps on board.
The only thing you need to do to make them work is connect audio signals to the inputs on the control panel
of the sub, connect the 2 satellite speakers with speaker cables to the sub, connect the mains cable, switch
on the unit and adjust the volumes of sub speaker and satellites.
The signal fl ow in the SUB PA is as follows:
The full-range left and right signals go into the sub and are separated into a left and right low and a left and
right mid-high signal. The left and right low signals are mixed together and pass trough a limiter, then are
amplifi ed and sent to the woofer in the sub cabinet. The left and right mid & high signals pass each trough a
limiter, then are amplifi ed separately and sent to the 2 satellites. In the satellites the signal is separated again
into mid and high and sent respectively to the internal mid speaker and horn tweeter.
We will now show you step by step how to get the best results.

The inputs (1) and (2) are a combination of a phone plug and XLR plug. In the middle there is a ¼
phone jack (1); The female XLR input is in the outer ring (2) . The use of the balanced XLR input is
recommended over the use of the unbalanced phone plug input as noise levels will be much lower.
1. JACK INPUTS: These high impedance ¼" jack sockets accept unbalanced signals. We recommend the
use of a high-quality shielded audio cable to prevent any background noise interference or unwanted feedback.
2. XLR INPUT: These line level, balanced female XLR connectors are designed to only accept signals from line
level equipment with balanced output such as a mixing console, a tape machine, or another Powered Speaker
Cabinet. When the distance between the external audio device and the powered speaker cabinet exceeds 15
feet, a balanced cable should preferably be used to minimize signal loss. Wiring of the 3-pin connector is: Pin 1=
Shield; Pin 2 = Positive (Hot); Pin 3 + Negative (Cold).
3. XLR OUT: These low impedance line outputs with XLR male connectors can be connected to an other active
speaker or sub set with a balanced input
4. Speaker OUT: These speaker out connectors are used to sent the amplifi ed mid/high signals to the satellites.
