INSTRUMENT
INPUT: This input is designed for all passive and active type
pickup signals. When a plug is inserted, the 9V battery is switched
on.
INSTRUMENT OUTPUT: This is a "parallel"
jack which can be used to send the "guitar/instrument signal" to an
external tuner, guitar amp or other device which can use an instrument
level signal.
EFX LOOP: This
is a real world "EFX LOOP".
In an effort to save room, most of our competition uses a TRS jack (tip,
ring, sleeve) and Y cable type system. The DI+ is provided with two
1/4" jacks, one for "SEND" and one for "RETURN". Since the EFX LOOP
interrupts the signal path it can be used as an insert point for a volume
pedal, compressor, or tuner, if the tuner is equipped with a bypass
switch. (Try that with one of our competitors
units)
SEND: The signal on the SEND jack is post-input
gain and pre EQ. This means that you can use the SEND signal as an auxiliary
unbalanced direct output. This signal is not affected by any of the
panel controls with exception of the "INPUT GAIN" control.
RETURN: A plug inserted into the RETURN
jack will interrupt the signal path. The signal on the tip of the plug
inserted into the RETURN jack will be the signal that the DI Plus will
process.
INPUT GAIN: The "INPUT GAIN" is not a volume
control, rather this control sets the level of amplification applied
to the input signal to boost it to a useable level. The reason this
is adjustable is to accommodate a wide range of pickup devices.
BASS: This is an "Active" control. The BASS control adjusts the amount
of cut or boost in the low frequency (150HZ) range.
TREBLE: This is an "Active" control. The
TREBLE control adjusts the amount of cut or boost in the high frequency
(5kHZ) range.
NOTCH FILTER: ON/OFF - Enables or disables
the NOTCH FILTER control.
FREQ. HZ - Sets the frequency (100-350HZ)
of the 18db cut NOTCH FILTER that is used to control resonant feedback.
SHAPE: ON/OFF - This toggle switch enables
or disables the SHAPE control. This control is a mid dip control. In
the ON position, the mid frequencies will be cut and the high and low
frequencies will be boosted.
XLR LEVEL: This control adjusts the amount
of signal sent to the XLR OUT jack.
LINE LEVEL: This control adjusts the amount
of signal sent to the LINE OUT jack.
48V : (Phantom Power) This LED lights when there is 48V Phantom Power
present on the XLR OUT jack. No battery drain will occur when Phantom
Power is present.
POWER: This
LED indicates the DI PLUS is ready to operate. The POWER LED will illuminate
when:
A. A plug is inserted into the INPUT jack and there is a fresh battery
installed in the DI PLUS.
B. A 9VDC adapter (Wall Wart) is plugged into the power jack.
(9VDC Regulated Power Supply - 500mA) (2.1MM DC Power Plug, Center +)
C. There is 48V phantom power on the XLR cable plugged into the XLR
OUT jack. (The 48V LED and the POWER LED will both be illuminated.)
XLR OUT: Plug a standard XLR cable from
your PA or recording console into this low impedance balanced output.
Use the "XLR LEVEL" control to set the output level which matches up
best with your PA or recording gear and gives you the least amount of
noise. If your board provides 48V phantom power on the XLR cables, the
DI Plus will run from this and save the battery. It is suggested that
you keep a battery in the unit as a backup when using the phantom power.
If the phantom power drops, the DI Plus will automatically switch to
battery power.
LINE OUT: This is a standard unbalanced
line level output signal. Use the "LINE LEVEL" control to adjust the
signal level on this jack. This output can be used simultaneously with
the XLR OUT jack for some creative signal routing. Plug a standard instrument
cable from this output to a stage monitor amp or unbalanced Mic input
on a mixer.
