Description

The AMP1-DA/106 provides self-powered, full-fidelity 
stereo audio monitoring of 2 channels from analog 
and AES/EBU Digital sources and ultra-high 
resolution LEDs with 106 segments in the smallest 
rack space possible.

This unit contains four high performance transducers 
driven by three power amplifiers: one amplifier/driver 
combination handles midrange and high frequency 
information in stereo, while the second handles 
summed low frequency information below the 500 Hz 
crossover point.

The unique design provides optimally focused sound 
for operators in an ultra near field (1 to 3 ft.) working 
environment and offers performance comparable to 
that of many separate monitor pairs, yet does so 
without the installation hassles, awkward speaker 
placements and “added-on” look. This provides for a 
higher SPL for the operator while reducing overall 
ambient sound and adjacent bay crosstalk.

The level meters are now available with a choice of 
BBC, DIN, Nordic and VU scales and PPM Only.

Extended HF response reveals potential problems 
with audio whine or hiss and electronic rather than 

acoustic cancellation of bass frequencies provides 
positive audible detection of out-of-phase (reversed 
polarity) audio feeds. A headphone jack is provided on 
the front panel, usage automatically mutes the 
speakers.

Output limiter circuits are incorporated to protect the 
speakers, and extensive magnetic shielding allows 
placement immediately adjacent to video monitors 
with no color impurities.

Our unique tri-color LED design means we can offer 
an almost unlimited variety of options such as phase 
correlation, peak hold, loudness, sum and difference, 
and alternate scales and color mappings. The 
standard display mode is set as a single segment 
PPM “dot” above a VU bar; each segment’s color is 
fixed according to its position on the scale. Level 
calibration may be set via dip switches to select one of 
four different calibration levels.

The AMP1-DA/106 is ideally suited for use in VTR 
bays, mobile production vehicles, teleconferencing 
installations, multimedia systems, satellite link and 
cable TV facilities, and on-air radio studios.
