RECORDING CONNECTIONS
Analog audio signals are created by microphones, synthesizers, mixers, and
instruments with magnetic pickups. Of these sources, microphones and magnetic
instrument pickups have the lowest output level, and generally require the most
amplification. Keyboards, preamps, and mixers output “line-level” audio, which varies
with each device between the -10 dBV and +4 dBu standards.
CONNECTING A MICROPHONE
Plug an XLR cable directly from a microphone into the desired
Mic
input on the
Lambda Studio rear panel.
TO ACTIVATE PHANTOM POWER
If your microphone requires phantom power, first make sure the microphone
is connected, then press the Phantom Power switch (labeled
+48V
). The +48V
Phantom Power LED on the front panel indicates the phantom power is active. If
your mics don’t need phantom power, it is best to leave it off.
USING THE ANALOG INSERTS
The analog inserts require an insert cable (¼" TRS to 2 x ¼" TS). The signal from
the tip should be routed to the input of your outboard processor and the output of
your processor should be routed to the ring.

CONNECTING A LINE-LEVEL SOURCE
Plug a ¼" TS (unbalanced) or TRS (balanced) cable directly from the line-level
source into the desired
Line In
jack on the rear panel of the Lambda Studio. Line-level
sources include keyboards, drum machines, CD and cassette players, and external
microphone preamps and effects. If the line-level source has something other than ¼"
outputs, cable adapters can be used.
NOTE:
When using the
Line In 1
input, DO NOT plug a cable into the
Instrument
input. Inserting a cable into the
Instrument
input disconnects the
Line In 1
input internally.
CONNECTING AN INSTRUMENT
Plug a standard ¼" TS (instrument) cable directly from the instrument into the
Instrument
input jack on the front panel of Lambda Studio. Note that this will disable
the
Line In 1
jack on the back panel.
IMPORTANT:
To avoid damage,
do not plug a line
output into the Mic
1-2 jacks unless the
+48V (phantom)
switch is turned OFF.
For the cleanest
recording, adjust
the Gain so the level
reaches at least
-6 on the input
bargraph meter,
but never lights the
“Clip” LED on the
loudest sound you’ll
be recording. If you
see the Peak LED
light constantly, turn
the Gain knob down
until it flashes only
occasionally, on the
loudest part of the
performance.
DO NOT TURN
DOWN A GAIN
CONTROL TO GET
THE RIGHT MIX IN
YOUR HEADPHONES
OR MONITORS
WHILE RECORDING.
USE THE MONITOR
MIX CONTROL FOR
THIS PURPOSE.
