Signal Adapter SA-1 enables to adjust the signal level in the amp effects loop to the signal level required by effects. SA-1 let you avoid distortions caused by to high signal level or reduce hums caused by to low signal level. Signal adjustment is done by two separated modules: ATTENUATION and BOOST. When the signal which goes to the effect is to high SA-1 attenuates it and boosts the return signal. When the signal which goes to the effect is to low SA-1 boosts it and attenuates the return signal. On the front panel of SA-1 there are attenuation and boost regulators for matching the signal of both sections. Adapter can be installed in the rack 19” using the GLAB 1U RMS FRONT PANEL.

Basic characteristics:

• fully passive ATTENUATION module working in the range up to -16 dB ( /6 ),
• BOOST module based on class A power amp working in the range from 0 to 14 dB ( x5),
• high level of the BOOST module transmitted signal - 19 dBu (19Vpp),
• PEAK indicator of crossing the BOOST module maximal signal level (>18 dBu),
• durable, powder-coated casing,
• possibility to install in the rack,
• 9V DC power supply.
