FRONT PANEL CONTROLS AND CONNECTORS (2) (3) (4) (4a) (5) (6) (7) Front Panel (8) (9) (1) POWER SWITCH Use this switch to power unit ON or OFF. The integrated LED will light when the unit is ON. Before turning on this unit, verify connection to the proper voltage AC source, check all connections and turn down the level controls of equipment connected to the outputs. (Note: The TMP-3 will not output audio for approximately 16 seconds after power up due to the time it takes for the tubes to warm up. Do not turn up the audio until after this warm up period to avoid possibly damaging speakers or your hearing due to improper level settings.) (2) +30dB GAIN/NORM SWITCH Use the +30dB GAIN/NORM switch to set the gain range of the INPUT CONTROL (2). When the switch is out, the TMP-3 operates in Normal mode, depressing the switch adds +30dB of gain. Push the switch in for microphone applications when more level is needed. (3) PHASE REVERSE / NORM SWITCH When the switch is in the Out position the output signal is normal. Depressing the switch reverses the phase of the output signal. In multi-microphone applications, mic placement can affect the phase of the signals. If your sound is "thin" or "not quite right", reverse the phase to correct the problem. (4) PHANTOM POWER SWITCH Use the PHANTOM POWER to supply power to all microphones requiring +48V phantom power. The TMP-3 phantom power is engaged and disengaged with this switch Phantom power is applied to pins 2 and 3 of the XLR INPUT (20) jacks when this switch is pushed in. To disengage phantom power, set the switch in the out position. PHANTOM POWER LED (4a) lights when PHANTOM POWER is engaged. (5) GAIN CONTROL Controls the amount of gain in the tube mic preamp circuit. This control adds from 0dB to +10dB of gain. (6) CLIP LED When lit, this LED indicates clipping or possible distortion in the mic preamp circuits. Reduce the GAIN CONTROL (5) so that this LED only lights occasionally. (10) (11) (12) (13) (14) (15) (1) (7) LOW LEVEL EQ CONTROL Adjusts level of low frequencies, from 20Hz to 150Hz. (8) MID LEVEL EQ CONTROL Adjusts level of mid frequencies, as selected by the MID SWEEP (9) control. This sweepable filter has a Q or width of 1. (9) MID SWEEP CONTROL Selects the frequency to be boost/cut by the MID LEVEL (8) control. Adjustable from 300Hz to 5KHz. (10) HIGH LEVEL EQ CONTROL Adjusts the level of high frequencies, from 10kHz to 20kHz. (11) IN/OUT SWITCH Switch for engaging the compressor circuits. The compressor is active when the switch is in. (12) THRESHOLD CONTROL Sets the point that the input signal must reach for compression to begin. (13) RATIO CONTROL This control sets the signal to compression ratio. This ratio relates to the amount of increase of input compared to output signal. Thus, for example, at a 1:1 ratio, a 1dB increase of input signal will result in a 1dB increase of out signal. At 2:1, a 2dB increase of input signal will result in only 1dB increase of output signal. At 8:1, an 8dB increase of input signal will result in a 1dB increase of output signal. (14) OUTPUT LEVEL VU METER The output level of the TMP-3 can be monitored using the analog OUTPUT LEVEL VU METER. The meter's 0dB marking represents +12dB at the XLR output and +6dBu at the 1/4" output. The output meter will also reflect any attenuation due to the output limiter when it is engaged. (15) OUTPUT CONTROL The OUTPUT CONTROL sets the output level of the TMP-3. When the control is fully counterclockwise, the output level of the TMP-3 is zero. Turning the control clockwise increases the level of the output to a maximum of +10dB of gain. This gain is in addition to the existing input gain. 5
