Can I use the Trim-Two on instruments such as acoustic guitar or bass?

The Trim-Two is designed for buffered signals. This means that it can be used with an active source such as an active bass or acoustic guitar with built-in electronics. However, the transformers in use are not designed for instruments. The ProDI or ProD2 would be a better choice.

Will phantom power from my mixer harm the Trim-Two?

No. The internal transformers will block the 48V phantom power.

Can the Trim-Two be connected to the line input of a mixer?

Yes. However the Trim-Two is a passive device that will only pass the signal from the source. This means that if the source level is low, the output may be too low to drive a line input.

Why is there no pad switch on the Trim-Two?

It is not required. The 'trim' level control replaces a traditional pad.

Where does the Trim-Two derive its power?

No power is needed. The Trim-Two employs two very efficient Eclipse transformers to manage the signal path. These passive devices do not require power to make them work.

Will the Trim-Two change the tone of the source?

Although all electronic devices impart some degree of personality on a signal, the exceptionally good performance of the two Eclipse transformers will yield a very natural tone with very low distortion.

What is the output level of the Trim-Two?

Unlike a typical DI box that reduces the input to produce a mic level output, the Trim-Two is a unity gain device. In other words, the output closely mimics the input. Simply set your mixer's input sensitivity to match.

Why should I not use the Trim-Two on a passive bass?

Because passive instruments have very low outputs and the transformers inside the Trim-Two are optimized for higher output instruments such as keyboards.

Can I use the Trim-Two on a speaker output?

No. A speaker level output could damage the Trim-Two.

Can I connect an unbalanced source to the Trim-Two?

Yes. To build the appropriate XLR to ¼" cable, connect the pin-2 hot to the tip and the pin-1 ground to the sleeve. This will likely reduce the balanced output by 6dB but this can easily be made up by increasing the level on the Trim-Two and the mixing console.
