Alto TS312 vs TS315
While both of these models belong to the same TS series from Alto, they are intended to deliver full-scale high-quality audio and are necessarily the same. However, they differ substantially because TS312 has 12-inch woofers, while TS315 is created with 15-inch ones.
While both of the models encompass the same characteristics and features as they originate from the same series, TS315 packs just a bit more of a punch. 15″ woofers would be capable enough to expel more air than the 12″ woofers and would thus produce an increased and maximum sound pressure level—this is where the main disparity stems from.

Therefore, the short technical explanation to the difference is that when all other components are similar, the TS315 is louder and tighter than the TS312 and will give more bass. Hence, you can feed it much more power and obtain extra volume, however for the low-frequency indications, this size rating is crucial, as they may be otherwise indistinguishable.
Alto TS315 Manual
To get the most out of a powered loudspeaker, you must use it accurately, and as instructed otherwise, it will fall short. We have explained how to set your product up to ensure it delivers all that it promises.
Mounting
The first and most crucial step is mounting. Always install subwoofers in agreement with acceptable electrical and building codes and according to its maximum weight. Test the specifications of your stand to assure it can bolster the loudspeaker’s weight. Furthermore, examine all safety precautions stipulated by the manufacturer. Do not mount numerous speakers on a similar stand. Confirm that the stand is on a steady, level, and flat surface.
You must analyze the stand before using that no parts are missing or got worn out. Be careful in windy, outdoor situations. You may need to position an extra weight on the stand’s base to expand stability. Do not attach anything to any part of a loudspeaker system as they can topple the system.
Unless you are sure that you can handle the loudspeaker’s weight, ask for additional help in mounting it. Ensure your wires are out of everyone’s way, so they don’t get tangled in the performers’ production crew’s or audiences’ feet and destroy the entire system.

Power Input
Connect the included power cable to the input area provided, connect the other end of the cable to a power source, and make sure the Power Switch is off while plugging and unplugging the cable.
Fuse
If the unit’s fuse faces wreckage, power off the loudspeaker and detach it from the power outlet, and then lift this flap to repair the fuse. Replace it with a fuse that has the relevant rating. Using a fuse with an inaccurate rating can defect the unit and fuse.
Power Switch
Turn the speaker on or off. Ensure the volume knob gets set to zero before turning it on, the power LED will illuminate when it is on.
Outputs
Attach the outputs to a loudspeaker using regular XLR cables. The audio signal that have frequencies above the crossover frequency of the subwoofer will get sent out of these outputs.
Inputs
Use a standard XLR cable to connect your sound source to these inputs.
Volume
Adjust the output volume accordingly with this knob, but don’t subject yourself to excessively constant loud sounds as they can damage your hearing.
Signal
This LED will light green when an audio signal gets transmitted to the subwoofer; the LED will flash at lower levels and lights up brightly at higher levels. The LED lights up red when the output limit is active, but if the LED shows light red continuously, decrease the volume of your audio source.
Polarity Reverse Option
Use it to overturn the phase of the speaker’s output. Use this to lessen phasing or cancellations caused due to the speaker’s location in a listening space.
Output Mode
Use it to Toggle between six different settings selections that modify the delay, crossover frequency, and the level of the XLR outputs. The first four settings are tailored for TS315 full-range loudspeakers. When a parameter is selected, its related LED will get illuminated
