pool, etc.).  
3. This product should be used only with a cart or stand that will keep it level and stable and prevent wobbling.  
4. This product, in combination with headphones or speakers, may be capable of producing sound levels that could cause  
permanent hearing loss. Do not operate for a long period of time at a high volume level or at a level that is uncomfortable.  
If you experience any hearing loss or ringing in the ears, you should consult an audiologist.  
5. The product should be positioned so that proper ventilation is maintained.  
6. The product should be located away from heat sources such as radiators, heat vents, or other devices  
(including amplifiers) that produce heat.  
7. The product should be connected to a power supply only of the type described in the operating instructions or as marked on the  
product. Replace the fuse only with one of the specified type, size, and correct rating.  
8. The power supply cord should: (1) be undamaged, (2) never share an outlet or extension cord with other devices so that the  
outlets or extension cords power rating is exceeded, and (3) never be left plugged into the outlet when not being used for  
a long period of time.  
9. Care should be taken so that objects do not fall into, and liquids are not spilled through, the enclosures openings.

A.  
B.  
C.  
D.  
E.  
The power supply cord or the plug has been damaged.

INSTALLATION  
To ensure years of enjoyment from your NADY AUDIO TMP-1 please read and understand this manual thoroughly before  
using the unit.  
INSPECTION  
Your TMP-1 was carefully packed at the factory in packaging designed to protect the units in shipment. Before installing and using your  
unit, carefully examine the packaging and all contents for any signs of physical damage that may have occurred in transit.  
(Note: Nady Systems is not responsible for shipping damage. If the unit is damaged, do not return to us, but notify your dealer and the  
shipping company immediately to make a claim. Such claims must be made by the consignee in a timely manner.)

RACK MOUNTING  
The TMP-1 fits into one standard 19" rack unit of space (1 3/4"). Parts of the unit can become very warm during use. This is normal  
during operation. Care should be taken to ensure that there is enough space around the unit for cooling (at least 12or 30cm). Do not  
place the TMP-1 on high temperature devices such as power amplifiers, etc., or the unit may overheat in operation. Also, do not place  
the unit on speakers as this may cause them to move and/or fall due to speaker vibrations.  
Although the units chassis is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely high fields of RF  
and EMI should be avoided.  
POWER CONNECTION  
The TMP-1 has an internal power supply and is designed to operate from an external AC source. Power requirements for electrical  
equipment differ from area to area. Be sure to confirm that the voltage selected by the voltage selector switch on the back panel is  
proper for your area (120VAC/60 Hz or 230VAC/50Hz) per the information below:  
Europe (except UK): 230V, 50Hz  
UK and Australia: 240V, 50Hz  
USA and Canada: 120V, 60 Hz  
For other areas, please check with local authorities.  
When ready to operate, plug the AC cord into the power source. Make sure that the unit is turned off before connecting to the AC  
power source to avoid possible loud transients which can damage your speakers or your ears, especially when monitoring with  
headphones.

(5) OUTPUT LEVEL VU METER  
The output level of the TMP-1 can be monitored using the analog  
OUTPUT LEVEL VU METER. The meters 0dB marking repre-  
sents +12dB at the XLR output and +6dBu at the 1/4" output. The  
output meter will also reflect any attenuation due to the output  
(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 limiter when it is engaged.  
and turn down the level controls of equipment connected to the  
outputs.  
(6) CLIP/LIMIT LED  
(Note: The TMP-1 will not output audio for approximately 16  
The CLIP/LIMIT LED lights green when the unit is powered. The  
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.)  
LED also functions as a clipping and limiting indicator. The LED  
lights red when the audio signal reaches 6dB below hard clipping.  
If the OUTPUT LIMITER SWITCH (8) is depressed, the LED will  
light red when the limiter engages at which point the gain will be  
reduced automatically to avoid clipping.  
(2) INPUT CONTROL  
The INPUT CONTROL sets the amount of input gain of the  
TMP-1, turn the control clockwise to increase gain and counter-  
clockwise to decrease gain. You may control two ranges of gain  
with this control, +26 to +60dB and +6 to +40dB. Selection of the  
gain range is made with the +20dB GAIN SWITCH (3)  
(7) PHASE REVERSE / NORM SWITCH  
When the switch is in the Out position of the output signal is  
normal. Depressing the switch reverses the phases of the output  
signal. In multi-microphone applications, mic placement can affect  
the phase of the signals. If your sound is thinor out of position,  
reverse the phase to correct the problem.  
(3) +20dB GAIN/NORM SWITCH  
Use the +20dB GAIN/NORM switch to set the gain range of the  
INPUT CONTROL (2). When the switch is out, the TMP-1  
operates in Normal mode, depressing the switch adds 20dBs of  
gain. For microphone applications, where more level is needed,  
push the switch in.  
(8) OUTPUT LIMITER SWITCH  
When this switch is depressed the output level is limited to 0dB for  
the 1/4 output and +6dB for the XLR output. This is specially  
designed to prevent clipping of the audio waveform. This also  
reduces the possibility of overload to any units connected to the  
outputs of the TMP-1.  
(4) PHANTOM POWER SWITCH  
Use the PHANTOM POWER to supply power to all microphones  
requiring +48V phantom power. The TMP-1 phantom power is  
engaged and disengaged with this switch Phantom power is  
applied to pins 2 and 3 of the XLR INPUT (13) jacks when this  
switch is pushed in. To disengage phantom power, position the  
switch in the out position.  
(9) OUTPUT CONTROL  
The OUTPUT CONTROL sets the output level of the TMP-1.  
When the control is fully counterclockwise the output level of the  
TMP-1 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.

(Note: Only one output (1/4" or XLR) can be used at one time. Do  
not connect to both at the same time, or the signal will be  
severely distorted.)  
This standard IEC power cord receptacle is used to connect the  
AC power to your unit. It features a built-in fuse holder for a  
5X20mm, 0.5A/250V slow-blow fuse. If the fuse continuously  
blows, shut off the unit and have it serviced by qualified service  
personnel.  
(13) INPUTS  
Unbalanced 1/4"(6.3mm) and balanced XLR inputs.  
(11) AC VOLTAGE SELECT SWITCH  
(Note: Only one input per each channel (1/4" or XLR) can be  
used at one time. Do not connect to both at the same time or the  
signal will be severely distorted.)  
Before plugging in the power cord, check to see that the unit is set  
for the proper voltage for your area: ~115V (60Hz) or ~230V  
(50Hz).  
(Note: Use at the improper voltage can damage your unit and void  
the warranty.)
