Ch1 Xlr Mic Input; Insert Send And Return; Insert Send; Amp Out - Grace FELiX2 Owner's Manual

TRS 1/4" jack wired Tip signal to CH2, Ring signal normaled to
CH1, and Sleeve ground. If you are using CH1 with this input,
remember to select the 'line' setting of the adjacent 'mic/line'
switch.
Both CH1 and CH2 line inputs have 3 input impedance settings,
selectable from the toggle switch labeled 'Z' . The settings are:
CH1: med - 1MΩ / hi -10MΩ / low – 10kΩ
CH2: med - 1MΩ / hi -20MΩ / low – 332kΩ
Some pickups or sources are more sensitive to preamp input
impedances than others. For example, if you use a 'Sunrise'
magnetic pickup, they prefer to connect with an input
impedance of 1MΩ. If you have an onboard preamp or a lower
impedance pickup, the input impedance setting will probably
make less of a difference. In any case, we encourage you to try
different settings with your pickup or source. The difference
may be noticeable or not, and should be set accordingly to
what sounds best to you. Always what sounds best to you!

8.2 CH1 XLR MIC INPUT

This input can accommodate any type of microphone, from a
SM57 to a large diaphragm condenser or even a ribbon mic if
you're feeling fancy. The connector is wired pin 2 positive, pin 3
negative and pin 1 ground. 48V phantom power, if activated, is
supplied on pins 2 and 3. If you are using this input, remember
to select the 'mic' setting of the adjacent 'mic/line' switch. The
side panel phantom power switch should always be set to
OFF whenever connecting or disconnecting this input. We
recommend muting Felix 2 before changing the setting of the
mic/line and 48V switches to avoid pops on the output.

8.3 INSERT SEND AND RETURN

The insert connections are buffered, unbalanced send and
return points for connecting outboard effects to Felix 2. Both
jacks are TRS connectors, which allows for mono, dual mono or
stereo outboard signal processing to be placed in series with
the output signal. Configuring these jacks to suit your exact
need may require setting internal jumpers J18 and J19 (see
page 12 for more details).

8.4 INSERT SEND

The send can be operated as mono, dual mono or stereo. In
mono / dual mono, signal from CH1 is on the Tip and signal
from CH2 in on the Ring. In stereo
The SEND TRS jack is wired:
• Tip - CH1 or MIX
• Ring - CH2
• Sleeve - Ground
The RETURN TRS jack is wired:
• Tip - CH1
• Ring - CH2
• Sleeve - Ground
NOTE: the inserts will only work if the output you are using
'source' is set to MIX - even if preamp is in A/B mode.

There is an internal jumper that allows the output level of the
INSERT send to be adjusted between 0dB, -6dB and -16dB,
which helps when interfacing with external effects that have
much lower headroom than the Felix 2. The factory setting is
-6dB. Configuration of internal jumpers is described in detail on
page 12.

8.5 AMP OUT

This output is for sending an unbalanced, non-transformer
isolated output to a stage amp or anywhere else you may need
an additional unbalanced signal. This output has a level control,
which is situated on the right side, bottom row of controls on
the top panel. This output is muted when the MUTE / tune
footswitch is activated.
When the Amp Out source switch is set for MIX, the output
is stereo with CH1 or MIX on the tip and CH2 on the ring. The
CH1or MIX is determined by the jumper settings on your insert
Send/Receive. When the Amp Out source select switch is set for
CH2, then CH2 (pre insert) is sent out on both the Tip and Ring.
To use the jack in mono, simply plug in a TS cable.

8.6 TUNER OUTPUT

This is another unbalanced output which is always active –
provided as a dedicated stage tuner out. When the MUTE is
activated, your stage tuner will continue to receive signal,
allowing you to tune silently. The Tuner output level follows
the Amp Out level control and is a mono-summed version of
whatever signal is on the Amp Out jack.
8.7 DI OUTPUTS, CH1 & CH2
These two outputs are balanced and transformer isolated for
sending signals to a front of house console, monitor console or
any mixer or interface. The XLR pinout is: pin 2 positive, pin 3
negative and pin 1 ground.
Each output can be sourced from either its individual channel
only (pre insert) or the blend of the two channels, adjusted
by the 'MIX' control on the far right of the top panel controls.
Source select is via the 'DI source select' switch above each XLR
output. Also, each output has an adjacent level setting switch
– line and mic – depending on what input this source will be
feeding. In the 'mic' setting, the output is padded down -26dB
to interface properly with mic inputs at the console, the 'line'
setting is not padded for better level matching with line level
inputs at the console or interface.
When configuring the Felix 2 with the insert FX LOOP, the DI
source select should be set to 'MIX' . For setups utilizing the A/B
mode and the FX LOOP there is an additional configuration
available. By default, both DI outputs are active when in A/B
mode. Additionally, there is an internal jumper that allows
the DI outputs to be configured for exclusive operation. In this
mode, when channel A is active, DI 1 is active and DI 2 is muted
and when channel B is active, DI 1 is muted and DI 2 is active.
This allows for individual DI outputs for each channel while
sharing the FX LOOP. See page 12 for details about how to
adjust this jumper setting.
