Frequently Asked Questions - TX215 ALTO

How to connect a microphone to the TX215?

Plug the microphone into the XLR/TRS combo input, then set the input selector to Mic. Adjust the volume gradually while monitoring the Limit indicator to avoid clipping.

What does the Contour switch do?

The Contour switch boosts bass and treble by +3 dB for a punchier sound. In the released position, the response is flat, ideal for neutral reproduction or to optimize power.

How to avoid damaging the speaker?

Do not exceed the volume setting that keeps the red Limit light on. Use the appropriate input selector (Line or Mic) and do not block the ventilation grilles.

Can I suspend the TX215 speaker?

No, the speaker is not designed for suspension. Use it only on a pole or on the ground. For suspension applications, refer to the Truesonic or Black series.

How to use the Ground Lift?

Press the Ground switch to reduce hum or noise caused by ground loops. Release it if the noise disappears without this function.

What is the meaning of the LED indicators?

The Signal (green) indicator shows the presence of an audio signal. The Limit (red) indicator lights up when the limiter is active; if it stays red, reduce the source volume.

How to replace the fuse?

Unplug the speaker, lift the fuse tab near the power input, replace it with a fuse of the same rating (indicated on the device) and close.

Can I plug an instrument directly?

Yes, for an instrument with active preamp, set the selector to Line. For a passive instrument, use the Mic position and gradually increase the volume.

How to daisy-chain two TX215 speakers?

Use an XLR cable to connect the Link output of the first speaker to the input of the second. Ensure the selectors are set to Line and that the source volume is not excessive.

What type of cable to use for audio input?

Use a balanced XLR cable or a 6.35 mm TRS jack cable (not included). For a microphone, prefer XLR.

Important Safety Precautions

Please note: Alto Professional and inMusic are not responsible for the use of its products or the misuse of this information for any purpose. Alto Professional and inMusic are not responsible for the misuse of its products caused by avoiding compliance with inspection and maintenance procedures. Please also refer to the included safety and warranty manual for more information.

Caution: To reduce the risk of electric shock, do not connect a TX2 Series loudspeaker to a power outlet while the grille is removed.

Stand-Mounting

Important: Do not suspend a TX2 Series loudspeaker. It is not designed for suspended applications. We recommend our Truesonic (TS) Series or Black Series loudspeakers for suspended applications instead.

• Always install loudspeakers in accordance with applicable electrical and building codes.
- Install the loudspeaker according to its maximum weight. Check the specifications of your stand or pole to ensure it can support the loudspeaker's weight. Also, observe all safety precautions specified by the manufacturer.
- Do not mount multiple loudspeakers on the same stand or pole.
- Always verify that the stand or pole is on a flat, level, and stable surface. Also, fully extend the legs of tripod-style stands, and ensure its legs do not present a trip hazard.
- Inspect the stand (or pole and associated hardware) before each use and do not use equipment with worn, damaged, or missing parts.
- Always be cautious in windy, outdoor conditions. You may need to place additional weight (e.g., sandbags) on stand's base to improve stability. Do not attach banners or similar items to any part of a loudspeaker system. Such attachments could act as a sail and topple the system.
- Unless you are confident that you can handle the loudspeaker's weight, ask another person to help you lift it onto the stand or pole.
- Make sure your cables are out of the way of performers, production crew, and audience so they will not trip over them, pulling the loudspeaker off the stand or pole.

Sound Level

Permanent hearing loss may be caused by exposure to extremely high noise levels. The U.S. Occupational Safety and Health Administration (OSHA) has specified permissible exposures to certain noise levels. According to OSHA, exposure to high sound pressure levels (SPL) in excess of these limits may result in hearing loss. When using equipment capable of generating high SPL, use hearing protection while such equipment is under operation.

Hours per day	SPL (dB)	Example
8	90	Small
6	92	Train
4	95	Subway
3	97	High-level
2 100 Classical music concert
1.5	102	Riveting
1	105	Machine
0.5	110	Airport
0.25 or less 115 Rock concert

Setup

Volume Control (TX208 & TX210 only)

The TX208 and TX210 loudspeakers accept both line-level and mic-level audio sources. Before connecting your audio source, turn the Volume knob to the minimum position (fully counter-clockwise).

0 dB SIGNAL LIMIT | ○ | ○ | POWER LINE MIC VOLUME

Line-Level Audio Source

When using an audio source such as a mixer, CD/MP3 player or audio preamp, follow the outer/Line level band indicator.

If the Signal Limit LED is on, do not advance the Volume knob any further. Doing so may damage your TX2 loudspeaker.

In most circumstances, you will not need to turn the volume beyond 0 dB.

If your audio source has unusually low output, you may turn the Volume knob past 0 dB, but not past the Signal Limit indicator (as explained above).

0 dB SIGNAL LIMIT | ○ | ○ | I LINE MIC POWER VOLUME SIGNAL LIMIT | ○

Mic-Level Audio Source

Important: If you are using an instrument with active preamp, treat the instrument as a line-level audio source (as explained above).

When using a microphone or instrument audio source, follow the inner/Mic level band indicator.

Because the mic and instrument level is typically lower than a line level, you can use the full rotation of the Volume knob.

As you turn up the Volume knob, please observe the Signal Limit indicator. If the Signal Limit LED is on, do not advance the Volume knob any further. Doing so may damage your TX2 loudspeaker.

Examples

Items not listed under Introduction > Box Contents are sold separately.

Note: These examples show the rear panel used by the TX212 and TX215 models, though all four models in the TX2 Series have the same input and output.

Example A: Two Loudspeakers

Connect each of your mixer's main outputs to the input on a TX2 loudspeaker. If you are using a TX208 or TX210, do not turn the Volume knobs past the 0 dB position. If you are using a TX212 or TX215, make sure the input selectors are set to Line.

Rear Panel: TX208 & TX210

1. AC Input: Use the included power cable to connect this input to a power outlet. Make sure the Power Switch is set to off when connecting or disconnecting the cable.
2. Fuse: If the unit's fuse is broken, lift this tab to replace the fuse. Replace it with a fuse with an appropriate rating (printed under the unit's power cable input). Using a fuse with an incorrect rating can damage the unit and/or fuse.
3. Power Switch: Use this switch to power the loudspeaker on or off. Make sure the Volume knob is set to its minimum (counterclockwise) position before turning it on.
4. Power LED: This LED lights up when the loudspeaker is on.
5. Cooling Vent: Keep the area in front of this vent clear from obstructions. The fan behind the vent cools the amplifier, preventing overheating.
6. Volume: Turn this knob to adjust the loudspeaker's volume.

When using an audio source such as a mixer, CD/MP3 player or audio preamp, follow the outer/Line level band indicator. In most circumstances, you will not need to turn the volume beyond 0 dB. If your audio source has unusually low output, you may turn the Volume knob past 0 dB, but not past the Signal Limit indicator.

When using a microphone or instrument audio source, follow the inner/Mic level band indicator. Because the mic and instrument level is typically lower than a line level, you can use the full rotation of the Volume knob.

Please see Setup > Volume Control to learn more.

1. Input: Use a standard XLR cable (not included) to connect your audio source to this input. Make sure to set the Volume knob to the correct position.
2. Mix Out: Use a standard XLR cable (not included) to connect this output to the input of another loudspeaker (i.e., another TX2 loudspeaker).
3. Signal/Limit LED: This LED lights up green when an audio signal is sent to the loudspeaker—it flashes at lower levels and lights solidly at higher levels. The LED lights up red when output limit/protection is active—if the LED is lit red continuously, reduce the volume of your audio source.
