What speakers are in the Truesonic (TS) Column lineup?

The Truesonic Column series features 8- and 12-inch woofer models. They are aptly named TS108C and TS112C.

How many watts do the Truesonic Column speakers output?

The 8-inch model is 600 watts, and the 12-inch is 1200 watts. 

How do I assemble the Truesonic Column speakers?

1. Place the subwoofer base on a level surface. 

2. Attach the additional columns according to your needs. There are two column sections, one of which (the top-most section) is loaded with the loudspeakers. The other section can be used as a spacer to determine the height of the loudspeakers. The loudspeakers should be placed so that they are relative to your audience’s ears for best results. For instance, if you are playing at the same level as the audience, you may wish to add the middle spacer section so the loudspeakers are at ear height. If you are on a raised stage, you may wish to remove the spacer section so the loudspeakers are closer to the audience on the floor. To attach a section, simply insert the protruding end into the cavity, aligning the internal connectors, and gently push until it snaps into place. 

3. Connect your input and output devices, and then connect the subwoofer base to power. 

4. Power on the unit using the Power Switch on the subwoofer base and start playing! 

To disassemble, first power off the unit, and then gently pull apart the sections. Store the columnar sections in the included carrying bag when not in use.

What are the inputs on the Truesonic Column speakers?

Each Truesonic Column speaker has a minimum of two Combo XLR and TRS jacks that support both balanced and unbalanced audio. They also receive Bluetooth signal when you pair a supported Bluetooth Device. The TS112C also features an additional Combo jack with an instrument preamp and a line-level stereo input.

How do I pair my Truesonic Column speaker with a Bluetooth device?

To connect the speaker with a Bluetooth device follow these steps: 

• Hold down the pairing button for 3 seconds to initiate pairing.
• The blue LED on the speaker will flash, indicating that it is in pairing mode.
• Navigate to your device's Bluetooth device list and select ”Alto TS108C” or “Alto TS112C” to connect.
• Once paired, there will be a voice prompt stating the connection was successful, and the blue LED will be lit solid. 

Note: Pressing the pair button while in pairing mode will cancel the connection.

How do I stereo link two Truesonic Column speakers?

The Truesonic Column speakers have a stereo link mode that will allow two Truesonic column speakers to be paired wirelessly. To set up the stereo link mode do the following steps: 

• Connect one speaker to Bluetooth following the steps above. This will be the primary speaker.
• Hold the pairing button for 3 seconds to initiate stereo link. Do this for both speakers.
• Both speakers will beep to indicate they are in scanning mode, and the orange LED will blink. When they find each other, they will link automatically.
• Once the two speakers are successfully linked, there will be a confirmation chime, and the Orange LED will be lit solid.
• Press and hold the pair button on either speaker to disconnect. 

Once the speakers are in the stereo link, the Bluetooth Volume knob on either speaker will control volume for both speakers

Notes: 

• If you link the speakers first, only one speaker will connect to Bluetooth.
•  If pair mode is activated on both speakers (pair button held for 3 seconds), you may encounter trouble linking until pair mode is cancelled or times out. 
• The stereo link is only for Bluetooth signal only. 
• You can only link another speaker of the same size together, a TS108C and TS112C will not link.

Mix Out does not include Bluetooth signal, only analog inputs. 

Why are there Mic/Line switches, and what do they do?

The Mic/Line switches let you select your input so that you can turn up the volume without fear of overdriving your Truesonic Column speaker.  As a general rule of thumb, microphones will need to be amplified at a higher level than a line-level source, if using a microphone, choose Mic, and if using a passive pickup instrument, like a guitar, use inst (only available on TS112C- channel 3). If you are unsure of whether your input is Mic or Line, start with Line first and make sure your source volume is at 50-75% volume. If this is still not loud enough, turn your the channel gain all the way down, switch to Mic, and turn the channel gain up progressively until an appropriate volume is reached. Note: Amplifying a line-level source at Mic level can potentially damage your loudspeaker.

This process is also applicable to the Inst/Line switch on the TS112C.

Note: The Truesonic Column series are optimized to provide maximum output for your source when the volume knobs are turned all the way up (5 o’clock).

What do I do if there is a delay between my linked speakers?

If you experience a delay between two linked speakers, please first try pausing and restarting your audio. If that does not work, try powering off both speakers and then re-linking them. 

What does the CH EQ button do?

The CH EQ button optimizes the high and low frequencies of your Truesonic Column when you are unable to pair with a phone. There are two bands to adjust on the speaker, high or low, and to select which channel you're adjusting, you simply turn the EQ knob. While on High, turning the EQ knob on either channel will adjust the high frequency band of the EQ, and Low will adjust the low frequency band. 

What does the "Speaker Use" button do?

The speaker use button will adjust your speaker to control the output EQ based on what is streaming through your speaker

• EQ off setting is a flat setting for general use.
• The Live setting has a bump in vocal frequencies, and a cut in the low end frequencies.
• The DJ setting boosts the high and low ends for added clarity and thump.
• The Custom via app setting allows you to control the EQ using the  free Alto Pro app

How do I adjust the EQ settings on the Truesonic Column speakers?

The Speaker Use Presets provide one option for EQ adjustment. For greater control, the Alto Pro app offers a 6-band, parametric EQ for use with the “Custom via App” setting. You can manipulate the available sliders to get the sound you want, and then load it to your Truesonic Column speaker by pressing the “Load to Speaker” button. After setting the EQ you want, you can save your favorite settings for later use.

Is there a master volume for the Truesonic Column speakers?

No, there is not a master volume, although the individual channel volumes (separate from the Gain) are accessible from the Alto Professional App.

Note: All digital mixer controls in the app are applied post-gain control to the input channels. For best results, set your input Gain just below the clipping point before using the digital mixer controls. Changes on the physical speaker will also be shown in the App in real-time.

How do I turn the voice prompts off?

Press and hold the BT pair and TWS link buttons until you hear “voice off.” To turn it on again, do the same thing until you hear “voice on.”

Note: The voice prompt level is controlled by the BT volume knob.

Why is my Mic so quiet?

The mic preamp on the 1-2 channels only applies to XLR inputs. 1/4" mics will not have this applied.

Where can I download the Alto Professional App? 

The Alto Professional TrueSonic 4 App is available to download for free on the Android and Apple app store.
