Step 5: Power on the 2-LA-2. The purple LED above the power switch will light up.
Step 6: Unmute your monitors and apply signal to the left channel only. Slowly raise the level of the
signal being input until sufficient signal strength is achieved on the left channel meter.
Step 7:
Now it’s time
to hear the effect of compression on your signal. Set the Meter switch for the left
channel to its up (GR) position and, while continuing to apply input signal to the left channel, slowly
turn the Peak Reduction knob clockwise; as you do so, the left channel meter will reflect the amount of
gain reduction. You can compare the original, uncompressed signal with the compressed signal with
the use of the BYPASS/COMP switch in the center of the front panel. (NOTE: When in BYPASS mode, the
2-LA-2 does not restore signal to its original non-compressed level, so you may hear significant level
differences between the BYPASS and COMP settings if a great deal of Peak Reduction is being
applied.) As you increase the amount of compression (by raising the level of the Peak Reduction
control), the overall signal will be attenuated; turn the Gain knob clockwise to make up the difference.
Set the Meter switch back to its down (OUTPUT) position in order to view the final output level of the
left channel of the 2-LA-2 and ensure that you are applying the correct amount of makeup gain.
Step 8: Set the left channel LIMIT/COMPRESS switch to its up (LIMIT) position in order to hear the
effect of the 2-LA-2 in limiting mode, where a higher compression ratio is applied and only peak
signals are reduced in level.
Step 9: Repeat steps 6 - 8 above, this time routing signal to the right channel only and adjusting the
2-LA-2’s right channel controls as desired. Note that, in Dual mode, the two channels operate
completely independently of one another, giving you two discrete compressor/limiters.
Step 10: To hear the effect of the two compressors stereo linked, set the LINK/DUAL switch in the
center of the front panel to its up (LINK) position, and set the Peak Reduction and Gain knobs in both
channels identically.

Because the 2-LA-2 is a tube device, it needs several minutes to achieve stable operating
temperature. During warm-up, audio quality may vary slightly.
For more information, refer to the “Front Panel” and “Rear Panel” sections on pages 4 - 6
of this manual.
Because it can run quite hot, we
recommend you power off the 2-LA-2 when it is not being
used for extended periods of time.
