Always turn the SOLO/PHONES LEVEL con-
trol down before you put the phone on. Then
advance it for best levels with a typical sound
source. Engineers who fry their ears find
themselves with short careers.
You can also use the PHONES output to in-
dependently drive a separate tape recorder,
PA system or studio monitor amp. Instead of
using a low-cost “headphone amp” chip, we
use a high-current version of our main output
amplifier circuity — which is why it can re-
ally clean out your cochlea if you crank it up
too far. But that’s also what makes it a
very
clean signal source that’s, in fact, identical to
the quality of the other outputs (see APPLI-
CATIONS GUIDE for various hookups which
use the PHONES output).
NOTE: When you press any SOLO button, a
slight click will be heard in the headphones
when a solo switch is activated.
SOLO/PHONES LEVEL
This control adjusts the Solo and Headphone
levels simultaneously. The control range is from
off to loud enough to cause a frontal lobotomy
(see warning on the
previous page). Be-
cause SOLO/
PHONES LEVEL is
completely indepen-
dent of the Master
Faders, you can use
it to preview your
mix before fading up
the main outputs.
CAUTION: To
avoid speaker dam-
age, this control
should never be set
higher than the Main
Output (1/LEFT 2/
RIGHT) level prior to
activating the SOLO
TO MAIN button.
1/LEFT 2/RIGHT
(MAIN OUTPUT LEVEL FADERS)
This gallant team stands
guard over your precious
main output level. They pre-
fer to be stationed below or
at the “U” (Unity) setting.
The outputs on the other end are capable of de-
livering up to +28dBm. Many amplifiers or other
equipment inputs will go into clipping before
that. Consult the specs on your amplifier/device.
You may have to keep the CR-1604’s Main and
Phone faders
below the Unity gain level.
LEVEL
This 10-segment meter reflects the “unbal-
anced” output signal strength at the left and
right main outputs.
• When the meter shows “0”, the unbalanced
output level is 0dBu (0.775 VAC RMS).
• Remember that “balanced” output levels
are 6dB hotter than the level indicated on
the bar graph meter.
BNC LAMP CONNECTOR
The CR-1604 includes a socket and power
supply for a 12-volt goose-neck lamp. We rec-
ommend LittleLite lamps PN #12G or 12G-HI
(with high-intensity bulb). Consult your
dealer for the gory details.
NOTE: When the CR-1604 has been “Roto-
podded” (pod jack to the front) the BNC lamp
connector becomes inaccessable.
This concludes our guided tour of the
CR-1604’s controls. After a short intermission,
we will re-board the bus (
HA! Get it? Pun?
bus......? Oh well. ) and explore the CR-1604’s
input/output “pod.”
