Quick Start Guide
- Mute your studio monitors.
- Connect your LiNTEC to your mixing bus or patch bay then use balanced TRS cables.
- Set all of the Boost and Attenuate knobs fully counter-clockwise, to zero.
- Set the Power switch to ON, By-pass to OFF, and apply power. Pow-er LED meter will light up.
- Unmute your monitors, and verify that signal is passing to and from the unit.
- Send your desired signal through the LiNTEC.
- Adjust the controls and listen for changes in the program material.
- If you hear the controls affecting the character of your music, the unit is functioning correctly.
Basic Use
The LiNTEC works a little differently than other parametric or graphic EQs you
may have used in the past.
The three control knobs on the left of the LiN-TEC (Boost, Low Freq, and
Atten) affect low-frequency content. The Boost and Atten controls both affect
the frequency chosen by the Low Freq control.
The five control knobs on the right of the LiN-TEC (Bandwidth, Boost, High
Freq, Atten, and Atten Freq) affect high-frequency content. The Boost and
Atten controls each have their own corresponding frequency selectors, (High
Freq for the Boost control, Atten Freq affects the At-ten control.)
The Low-End Trick
Documentation for the original Pultec rather bullishly asserted “Do not
attempt to boost and attenuate simultaneously on the low frequencies.” So, of
course, that’s exactly what curious, rascally engineers did. The result of
this simultaneous boost/cut operation is a low-end boost below the selected
frequency, with a cut slightly above the selected frequency.
Because the bandwidth (Q) of the Boost and At-ten controls differ, the two
controls do not cancel each other out. This setting results in satisfying
thump and body that doesn’t risk muddying the midrange, and has been a not-so-
secret trick of engineers and producers ever since.
Try it, you’ll like it.
Meter Calibration
Meter should be calibrated so that 0 VU = +4 dB. This is controlled the the
master calibration set screw on the back of the unit.
Allow 1-2 minutes to let the LiNTEC warm up after powering on before
calibrating the meter’s zero-point — heat from the bulb can gently affect the
meter.
To calibrate, ensure that no audio is passing through the unit. Then, using a
flathead screw-driver, rotate the screw on the rear panel until the needle
rests on 0. Use very small movements… a little goes a long way in meter
calibration!
Voila! Meter calibrated.
Output Calibration
All LiNTECs are hand-calibrated at the factory to match each other at unity
gain within 0.2 dB for use in matched stereo pairs. This calibration is
measured with all controls set fully count-er-clockwise.
We doubt it will be necessary, but if you would like to re-calibrate your
unit, adjust the Output Calibration control on the back of the unit.
The 1731 op-amp
The LiNTEC’s “VINTAGE OPA 1731” is our take on the classic vintage 1731 op-amp
– the predecessor to the 2520, known for its smooth, punchy character.
We think you’ll like it as much as we do.
- Power switch: Turns the unit off.
- Bypass switch: Bypasses the EQ circuit, useful for A/B comparisons.
- VU Meter: Displays output VU level.
- (LF) Boost: Selects the amount of boost at the frequency selected by the Low Freq control.
- Low Freq: Selects the frequency affected by the LF Boost and LF Atten controls.
- (LF) Atten: Selects the amount of attenuation at the frequency selected by the Low Freq control.
- Bandwidth: Selects the width (Q) of the HF Boost control. Left=narrow, right=wide.
- (HF) Boost: Selects the amount of boost at the frequency selected by the High Freq control.
- High Freq: Selects the frequency affected by the HF Boost control.
- (HF) Atten: Selects the amount of boost at the frequency selected by the High Freq control.
- HF Atten Freq: Selects the frequency affected by the HF Atten control.
- TRS Output: Balanced line-level output.
- TRS Input: Balanced line-level input.
- Meter Calibration: Use this control to adjust the 0 VU point at +4 dB.
- Output Level: Use this control to adjust the output level of the LiNTEC to match that of another LinTEC for stereo use.
- Voltage setting: Select the voltage suitable to your region. Do not power the LiNTEC by inappropriate voltage.
- AC Adapter Input: ONLY use the supplied 12VAC to power this unit.
Note: For proper performance, balanced TRS must be used for all inputs and outputs.
