AMX Precis DSP User manual

PRECIS DSP DATA SHEET
The new Precis with DSP provides the ultimate solution for distributed audio. With robust
features like input gain control, and output volume, tone, balance and a 10-band graphic
equalizer, you have the power to send audio to any room at any time – exactly how you
want to hear it.
PROFESSIONAL AND CONSUMER AUDIO SOURCES IN PERFECT HARMONY
The Precis DSP features gain adjustment on each individual input allowing for normalization of all inputs
to eliminate perceived jumps in volume (which are really line level variances) as the user switches between
various sources.
ENHANCE THE BEAUTY OF SOUND IN EVERY ROOM
Deliver audio to each room to suit it’s unique accoustical characteristics. Each output on the Precis DSP
features full 10-band EQ adjustments as well as volume, tone and balance control. So whether the room is
large or small, filled with absorbent or reflective furnishings, now the audio remains perfect.

1 kHz, 4 kHz, 8 kHz, 16 kHz
-12 dB to +12 dB (in 0.5 dB increments)
10-BAND GRAPHIC EQUALIZER
The 10-Band Graphic Equalizer has 10 distinct bands for boosting or cutting
center frequencies. This is useful when “fine tuning” the acoustics of a
particular audio zone to suit the physical characteristics of the room or zone.
*The total through-system gain for any input/output pair cannot exceed +10 dB.
INPUT GAIN CONTROL
Input gain control is provided to normalize input signals that have differing line level
voltages. This eliminates the potential volume variances that can occur during switching,
particularly when combining professional and consumer audio devices in the same system.
BALANCE, TONE AND VOLUME CONTROL
Balance Range: 100% left to 100% right
