The Pro Acoustic Mix DI (PAMDI)
A
Powerhouse for Acoustic
Musicians
The Pro Acoustic Mix Di is a fully-featured, two-channel
mixer designed for working musicians. Each channel includes
our powerful new "Four Band, Tunable EQ," combining ease of
use with exceptional perofrmance. This powerhouse
outperforms bulky, expensive rack mount equipment, while
its ultra-compact design enables it to fit in most guitar
cases.
Use the PAMDI with any instruments that are equipped with
Active Pickups, Passive Magnetic Pickups and/or an Electret
Mic. The PAMDI can mix two instruments, an instrument that
has two pickups or an instrument that has a pickup and a
mic (such as our
iP-2 Dual System
with a Highlander
Internal Mic).

When used with two instruments, the volume and tone can be
preset for each instrument individually. Changing
instruments is as easy as hitting the mute buttons. Each
instrument can be tuned independently of the other while
the master output is muted.
Gain
precise control over your tone with "Four Band Tunable EQ,
eliminate feedback, control the level of reverb/echo,
connect directly to a PA or recording console via the
built-in DI and much more, with Highlander's Pro Acoustic
Mix DI.
“Another top-class tool from Highlander - this is
high-fi stuff. The combination of the Highlander pickup and
the Pro Acoustic Mix DI is unbeatable.”

The AD18 AC
Adapter supplies AC voltage, which is converted to DC in
the unit.
* 2nd Harmonic distortion, at the low levels that it occurs
in the Pro Acoustic Mix DI, is not audible. However, this
type of harmonic distortion is the prevalent type of
distortion in tube amplifiers and is associated with warm
sound.
Extended
Response:
During the course Highlander’s extensive research,
harmonics as high as 45KHz have been regularly measured
emanating from acoustic guitars. We are sure that many
acoustic instruments produce even higher harmonics. While
the human ear cannot detect frequencies this high, these
harmonics do have an effect on what we hear and perceive.
For example, it is well known that two frequencies that are
close in pitch generate “beat” frequencies.
Some musicians use these beat frequencies to aid in tuning.
These beat frequencies are actually the sum and difference
of the original pitches. If the difference between two high
harmonics(e.g. 40KHz and 42KHz) is 2KHz, this can be heard
even though the harmonics cannot.
Typically, in order to “roll off” the low end,
a phase shift is incurred. Our Extended Low End Response
insures that bass instruments will not suffer any phase
shift when their lowest notes are played through Highlander
equipment. Phase shift tends to cancel low notes and rob
the sound of its 'punch'.
These are just some of the reasons why Highlander strives
to produce equipment with Extended Frequency
Response.
