20/20bas BIAMPLIFIED SYSTEM CONNECTIONS AND OPERATION

Please refer to Figure 2.

1 INPUT SENSITIVITY This control has a 20dB range and compensates for different input signal levels. With the control at maximum, 1.1VRMS input will produce full amplifier output. If too much input signal is present, the amplifiers may overload, in which case the green LED at the front of the monitor will flash.

2INPUT CONNECTOR This jack has gold plated terminals and accepts both XLR and ¼" input plugs wired either balanced or single-ended. A 3- conductor ¼" TRS or XLR plug is necessary for balanced input connections, but unbalanced wiring can also use either 3-conductor plug with the minus input left either unconnected or grounded. A 2-conductor ¼" TS type plug will also work for unbalanced sources, which automatically grounds the minus input. The input connector wiring is printed next to the connector and is as follows:

NOTE: Use only good quality input connectors having industry standard sleeve dimensions. Some consumer grade ¼" TRS plugs do not provide reliable connections because of slight dimensional differences.

3LOW FREQUENCY TRIM This controls the low frequency shelving boost/cut filter. The LF Trim filter has effect at frequencies below 400Hz and is fully engaged below 100Hz as shown on the rear panel response graphic. When the LF filter is set to “0”, the 20/20bas is designed to produce a flat LF response in the common “on the bridge or just behind the console” speaker mounting location. Locating the monitors in-wall or in a corner may require a reduction of low frequencies while free-standing in the open may require an increase in low end output for proper tone balance. The calibrated LF Trim filter allows for personal preferences in any monitoring situation.

4HIGH FREQUENCY TRIM Use this calibrated control to vary the

20/20bas’ high frequency output above 2.6kHz by ±3dB to accommodate personal preferences.

5 POWER SWITCH 1 = ON 0 = OFF

When power is on, the green LED at the front of the speaker will illuminate.
