Phoenix Audio DRS-8 Description
ZenPro -15dB Pad Mod Explained:
If selected, we change the pad value from -30 to a more standard -15. The original mono and stereo DRS units use -30 values to accept line level signals, however most buyers of this 8 channel DRS8 are solely tracking with mics and we find this value more fitting. Unit is still under original factory warranty (2 years), and we stand behind our work for the same time frame.
The DRS-8 is an 8-Channel Mic-Pre Housed in a 2 rack-space high, 19” rack mountable
unit. All channels are individually controlled and separated from each
other.
The unit can operate from most AC mains inputs, but the mains selector switch
on
the rear
panel MUST be switched to the appropriate voltage position for your area,
otherwise
significant damage will result. This Unit must be connected to a safety
earth at
all times.
Front Panel:
Input Sens
Switch: The Input sensitivity switch is a rotary 9 position switch. It is
marked from -30 to
-70. This controls
the gain for the INPUT stage in 5dBu steps.
The switch
applies gain at all times and does not disconnect when using the Mic/Line
switch. It affects
both the
XLR and 1/4” jack inputs (see rear panel inputs) at once.
Mic/Line
switch: The Mic/Line switch allows the use of Mic or Line level inputs. The
input is in
LINE mode
when the switch is pressed in.
+48V
switch: The +48V switch applies industry standard 48V Phantom power to the
input
XLR/1/4”
jack. NOTE: The phantom power will be applied to BOTH the XLR connections AND
the 1/4”
Jack at the same time. Make sure the switch is OFF when using LINE inputs.
PH switch:
The PHase switch will reverse the PHase of the INPUT signal when pressed in.
HPF switch:
The High Pass Filter switch applies a filter to the INPUT signal when pressed
in.
This is
useful for eliminating low-level/frequency background hum from equipment such
as
noisy Air
Conditioning units.
Mute
switch: The Mute switch will mute the channel when pressed in.
Level
LED's: The LED meter is connected to the OUTPUT of each channel. This indicates
levels
being sent from the OUTPUT XLR on the channel and is useful for monitoring
levels
being sent
to other equipment. The meter has some hysteresis to make it easier to see fast
peaks in
the signal.
O/P Level
control: The Output level control is a rotary control. This affects the OUTPUT
level being
sent to the
OUTPUT XLR's and the Monitor D-sub connector. The resulting level will be shown
on the
LED Meter.
Monitor
Selector switch: The monitor selector switch is an 8 position rotary selector
switch.
The switch
selects each channel (one at a time) and sends it to the Output Jack on the
front
panel.
Monitor
Output Jack: The monitor Output Jack is a 1/4” Mono Jack socket. This can be
used to
send the
monitor signal directly to headphones or a monitoring system.
Mon Level
control: The Monitor level control is a rotary control and adjusts the output
level at
the 1/4”
Monitor Output Jack socket.
Rear Panel:
Mains Input
Connector: The mains input is via an industry standard IEC “Kettle lead” input
with
integrated
fuse carrier (500mA Quick Blow fuse). Special attention should be paid to the
mains
input
voltage.
V-Sel
Switch: The voltage selector switch MUST be set to correspond with the mains
voltage in
your area.
Input
Connectors: The Input connectors are XLR / 1/4” Jack “combo” sockets. These will
accept XLR
or 1/4” Stereo or Mono Jack plugs. Either type of input connector can be used,
at
any time,
in any channel. Special attention should be paid to the +48V switch position
(see
+48V
switch) when using LINE level inputs.
Output
Connectors: The output connectors are standard 3 Pin XLR connectors. These
outputs
are transformer-coupled
balanced outputs.
Monitor
Connector: The monitor connector is a 25 pin “D-sub” connector. This is wired
“Tascam”
standard. The output of all 8 channels are available on the connector. These
outputs
can be used
in addition with the main Output XLR connectors and can be sent to outboard
equipment,
patch bays, or monitoring systems. The output levels are controlled by the
Output
level
control on each channel. The output level will always be -8dBu lower than the
main
Output
XLR's.
