The S3H from Adam Professional Audio is an active studio reference monitor designed for horizontal orientation in medium-sized and smaller control rooms. Capable of delivering 1350W RMS of cumulative amp power, it features two 7” HexaCone woofers, one 4” dome/cone hybrid midrange driver, and a handmade folded-ribbon tweeter. The waveguides, Adam-designed mid- and high-range propagation systems (MPS and HPS), ensure a wide, stable sweet spot.
Developed for transparency, the S3H’s frequency response is an impressive 32 Hz – 50 kHz. A multitude of DSP options, from equalization to delay, are provided for tailoring the monitor to the room and to personal preferences. The back panel features an OLED display and a push-button/rotary encoder to allow modification of parameters. Connect a computer to the USB Type-A jack for convenient remote access to all the S3H’s settings.
Two inputs, balanced analog and AES3 digital, are available via XLR jacks. An XLR AES3 output is provided to route digital signal to the second monitor, necessary for correct digital signal flow. Vary input sensitivity and output level as needed. Load and save voicing presets for quick configuration of monitor options. If further tonal adjustments are desired, there is a 6-band parametric EQ with high-pass and low-pass filters. Use up to 5 ms of delay for timing adjustments.
Adam S Series monitors, custom-developed with no off-the-shelf components, are handmade in Berlin according to strict manufacturing tolerances.
