TOP – OPERATING CONTROLS, INPUTS & OUTPUTS

GROUND LIFT SWITCH (4)

Switches the XLR (7,10) PIN 1 (shield) from direct contact with ground in the event that hum occurs with the

input cables connected. Push IN to lift the ground.

INPUTS, Left & Right (7,10)

The line-level input is of the medium impedance balanced type. Jack (7, 10) is a combo female XLR and 1/4" TRS

connector.

INPUTS, Left & Right (14)

A pair of RCA phono jacks (14) wired in parallel with the above listed inputs.

The top or WHITE jack is the Left channel input, and the bottom or RED jack is the Right channel. Used to input

a signal from a consumer type signal source, such as a CD player, Cassette deck or Radio.

MASTER SYSTEM LEVEL (5)

Controls the gain (level) of both the Left and Right input channels at the same time, of the entire powered

stereo speaker system. It is used to directly set the system output level for a given input signal. It turns the

level of both the Subwoofer AND the Satellite speakers up or down at the same time. Clockwise rotation

increases the level, counter-clockwise rotation reduces it. The sound is full OFF when the control is rotated full

CCW. When set to a 12 o'clock position, the gain will match well with many mixers and sound sources.

SUB LEVEL (6)

Controls the gain (level) of the Subwoofer ONLY, allowing the balance between the bass and the rest of the

sound to be adjusted. When turned full CCW, the Subwoofer output is turned all the way OFF. When set to the

2 o'clock position, the Subwoofer output levels match those of the Satellite's. Turning the control up past the 2

o'clock position will result in bass that is stronger in level than the Satellite speaker's output.

If this control is turned all the way up full CW, then the bass and male vocals could become boomy and

ill-defined due to the excessive amount of bass relative to the mids and highs. At this fully CW setting, the

subwoofer may overload and exhibit obvious distortion and distress, even with moderate input levels. This

much bass boost is available for sources that are weak in bass, but should not be used for sources that are

strong in bass content.

POWER / CLIPPING LED (13)

This is located to the right and down from the MASTER SYSTEM LEVEL (5) knob. It is on, or GREEN, when power

is applied. It turns RED when any of the power amps clip, or when the input channel is overloaded.

THRU OUTPUTS (8,11)

These male XLR jacks provide a means to send the input signal on to another device, or to daisy chain the

TriFlex

II into another TriFlex II unit. These can also be used to connect a TriFlex II system for mono input

™

operation using a short XLR (or 1/4" phone jack) cable from the Thru jack to the other channel input jack. For
