[. . . ] It ranges from Off ( ) to MAX (maximum gain), with unity gain at the center position (1 o'clock). · The TH-15A is designed to operate with a +4 dBu signal when the LEVEL control is at the U (center) position. · The TH-15A can accept up to a +0 dBu signal by turning down the LEVEL control accordingly. Turning the LEVEL past unity will provide enough gain to connect a microphone directly. · NEVER connect the output of an amplifier directly to the input of the TH-15A. This could damage the active input circuitry of the loudspeaker. 1. INPUT This is a female XLR-type connector that accepts a balanced mic or line-level signal from a mixing console or other signal source. For small gigs, simply connect a microphone directly and adjust the LEVEL accordingly. 2. THRU This is a male XLR-type connector that produces exactly the same signal that is connected to the input jack. Use it to daisy-chain several TH-15A's together off the same signal source. 8 4. OLIndicator The OL (overload) indicator lights when the amplifiers in the TH-15A are near the clipping point. It is okay if the OL indicator blinks occasionally, because this means that the transient peaks are just reaching the maximum output of the amplifiers and you are getting the most from your TH-15As. If the OL indicator is blinking frequently or lighting continuously, turn down the LEVEL control [] on the TH15A or turn down the signal at it source (e. g. , the mixing console) until the OL indicator blinks occasionally or not at all. 8. LOWEQ This control gives you up to 15 dB of boost or cut below 80 Hz and it is also flat at the center position (U). This frequency range represents the punch in bass drums, bass guitar, fat synth patches, and some really serious male singers. 9. EQON/OFFSwitch This switch allows you to bypass the EQ section. When the switch is out (OFF), the EQ section is bypassed and the EQ knobs have no effect on the signal. When the switch is pushed in (ON), the EQ controls can be used to tailor the frequency response of the TH-15A. 5. HIGHEQ This control gives you up to 15 dB boost or cut above 1 kHz. The circuit is flat (no boost or cut) at the center position (U). Use it to add sizzle to cymbals, and an overall sense of transparency or edge to the keyboards, vocals, guitar, and bacon frying. Turn it down a little to reduce sibilance, or to remove high frequency hiss. 10. POWERSwitch Use this switch to turn the TH-15A loudspeaker on and off. The indicating LED above the POWER switch lights when the POWER switch is on and AC power is available at the linecord socket. A second power indicator is located on the front of the cabinet. 6. MIDEQ This is a midrange EQ control that provides 15 dB of boost or cut centered at any frequency between 100 Hz and 8 kHz. The MID EQ circuit is flat (no boost or cut) at the center position (U). This frequency range includes most vocals (male at the lower end of the range and female at the upper end of the range), and the fundamentals and harmonics for many instruments. 11. LineCordSocketandFuse Connect the detachable line cord to this IEC socket securely, and plug the other end into your AC outlet. Make sure the AC power is matched to the AC power indicated on the rear panel (under the IEC socket). The fuse is located behind the fuse cover, at the bottom of the IEC socket.
