ALTEC Q

1698 AMPLIFIED
MONITOR PANEL

DESCRIPTION

The ALTEC LANSING 1698 amplified monitpr
panel permits monitoring of seven channels, at
either line level or loudspeaker level. Part of
ALTEC LANSINGs new generation of sound prod-
ucts, it continues the tradition of reliability and
ruggedness in an attractive package.

The ALTEC LANSING 1698 has an amplifier sec-
tion with an input isolation transformer and an
input impedance of 10,000 ohms, allowing a
line~bridging impedance high enough not to dis-

turb the line being monitored The amplifier fea-
tures an integrated circuit and a 2-watt amplifier
output section plus a regulated power supply. This
amplifier uses only 6 watts of line power and the
power transformer will accept 120 Vac as well as
240 Vac Line power changes are made by strap-
ping. The 1698 can also be used with a 24-v0lt
battery; silent and automatic transfer from ac to dc
source occurs if ac line power fails. The 1698 is 3
rack units high, 51/4 inches deep, and uses an
ALTEC LANSING high quality loudspeaker.
