HARD-WIRED IN EAR BODY PACK XL

Dear customer:

You have decided to buy a Fischer Amps product. Thank you.

Please read this manual carefully prior to the first use, you will get important information for
use and safety of the unit. These safety and operating instructions should be retained for
future reference.

Should you have further questions, please do not hesitate to contact FISCHER AMPS.

Product Description:

The Body Pack XL has the same functional principle as the Fischer Amps Hardwired In Ear Monitor
Belt Pack plus

an additional Mic-In to add-on a microphone signal to the stereo or mono mix received.
The integrated low-noise microphone preamp has standard features such as 48V phantom power,
PAD switch to reduce the input signal by 20 dB, and gain control from +12 dB to + 60 dB. An
additional feature for the microphone input is the parallel out which allows to loop the microphone
signal.
The Body Pack XL is powered with a 9V battery or a mains adaptor (not included).
This Body Pack is a compact in ear solution not only for orchestra musicians who want to mix their
own microphone signal to the incoming in ear signal, but it is also an excellent tool for engineers to
monitor microphone signals.

Basic information on the use of in-ear monitoring systems:
CAUTION:

Using this system at too high sound levels may cause permanent hearing defects. Adjust the
volume so that you can hear sufficiently. Ringing in the ears can indicate that the adjusted
hearing level is too high. Use headphone systems with good fit which suppress the ambient
noise well. This allows that the required listening volume can be low which is kind to your
ears.

Description of the Actuators (Front Side) :
(1)

3.5mm (1/8“) Stereo Jack: Connection of the headphone system (minimum impedance 12 ohms per

channel)
Maximum output power 40 mW per channel into 20 ohms.

Tip = left signal, Ring = right signal, Sleeve = ground

(2)

Battery Control LED: This LED controls the capacity of the battery or rechargeable battery. After

switching on with a newly inserted battery the green LED lights. With
increasing operating time and decreasing battery power (remaining
capacity approx. 20%) the LED lights orange. When the LED lights red, the
battery should be replaced.

(3)

Volume Control: Adjusts the volume of the left and right side of the headphone for channels

1 und 2. The microphone signal is adjusted with a separate volume control.

(4)

Change-over switch Stereo/ Mono-Mix Mode
Stereo Mode: The device outputs the signal fed into the left input at the left headphone

and the right signal at the right headphone.

Mono Mix Mode: Channel 1 and channel 2 are mixed and output to both sides of the

headphone.

By means of the Pan (balance) controller the ratio between both channels

can be adjusted.

(5)

Pan (Balance) Controller
In Stereo Mode: Adjusts the balance of volume of channel 1 and 2 between the left and the

right headphone system.

In Mono Mix Mode: Adjusts the volume level ratio between channel 1 and channel 2. Channels

1 and 2 are output mutually to both headphone sides. In middle position
both channel levels are equal;
at left stop only channel 1, at right stop only channel 2.

(6)

Microphone Gain: Adjusts the gain of the microphone signal from 12 dB to 60 dB.

When the PAD switch is activated, the adjusted gain is reduced by -20 dB.

(7)

LED Microphone Signal: Controls the level of the microphone signal after the microphone preamp.

When LED 0 dB lights, the working level is adjusted correctly. Peak levels
cause the LED to light red for a short period of time, however, the LED may
not constantly light red.

(8)

PAD Switch: The PAD switch reduces the adjusted gain value by -20 dB (which is

required for signals with a higher level).

(9)

LOW Cut Switch: Adds on a 70Hz Low-Cut with 18 dB/oct. after the microphone preamp; this

reduces deep bass signals.

(10)

Microphone Volume: Controls the volume of the microphone signal at the headphone output

(L/R)

Description of the Actuators (Back):
(1)

DC-In Connector: Possibility to connect a 230V mains adaptor with DC output 9V with
(lockable) minimum 250mAh output current. When a battery or rechargeable battery is

inserted, the battery is switched off after plugging in the adaptor.
When unplugging the adaptor, the Body Pack XL operates with the battery.
Polarity (+ tip, - ring)

Fischer Amps offer a suitable mains adaptor with lockable DC plug.

(2)

Power On: Activates the voltage supply of the device. This switch is flush so that it is

protected against being inadvertently switched off.
Activation of 48V phantom power is only possible, when the device is
switched on.

(3)

+48V for MIC INPUT
(Activation of Phantom Power): Add-on of 48V phantom power for the microphone input.

Activate phantom power only when a microphone is connected which
requires phantom power. 48V phantom power should only be activated at
one of the devices which are connected to the microphone.

(4) – (5)

XLR Inputs (L/1) and (R/2): Connect the input signal from the mixing console.
Assignment: 1 = Ground

2 = Signal +
3 = Signal -

With asymmetric wiring, assign PIN 3 to Ground (bridge in connector plug).

Maximum input level +5dB

(7) MIC-INPUT: Symmetric XLR connector to plug in the microphone
(6) MIC-LINK-OUT: XLR output to loop the microphone signal to another microphone input.

Mic In (7) and Mic Out (6) are coupled and function even when the device
is switched off.

Mono Operation of Body Pack XL:

With mono monitor mixing, the signal is connected to one of the two input channels, the change-over switch is
set to „Mono-Mix“ (press (4) front side), and the pan controller is in middle position. Thus the mono signal is
output to both headphones.

Mono-Mix Operation:
This operation mode is the easiest way to create a user-specific monitor mix. An over-all mono mix of the band,

for instance, is supplied to channel 1, the signal of the musician to channel 2. Thus the musician can
individually adjust the optimum listening signal by means of the PAN controller (ratio of over-all mix and
instrument). The PAN controller has no effect on the microphone signal. The microphone signal is output at the
Headphones output with the same level for left and right.

Adjustment of the Output Level at the Source of Signal (Mixing Console) for Channel 1 (L) and 2 (R):

Adjust the output level at the source of signal (mixing console at approx. 0 dB to +3 dB) at the signal peaks.
This provides the In Ear Body Pack XL with an adequate input level so that there is sufficient power at the
headphones output. In addition, this prevents that high increases of the level such as feedbacks escalate the
headphone level. The input level limits the signal at approx. +5 dB.

Inserting the Battery or Rechargeable Battery:

Switch off the device, open battery cover on top of the housing, insert battery or NiMH rechargeable battery in
correct position of the pole into the battery receptacle (according to drawing), put on cover and close it.
Inserting the battery with the pole in incorrect direction will not cause any damage to the device (the device
simply does not function).
Either use a 9V block alkaline battery or a nickel metal hydride (NiMH) brand rechargeable battery with 7 cells
(8.4V) and minimum 270mAh capacity. We advise not to use 9V zinc carbon batteries since their capacity is too
low and they can leak.
The operating time with a 270mAh rechargeable battery is min. 4 hours. We therefore recommend to use such
rechargeable batteries due to economic reasons and the protection of the environment. FISCHER AMPS offer
special rackmount chargers for the use on stage with charging times of 2 – 3 hours as well as high-quality
rechargeable batteries. When operating the Body Pack XL with add-on phantom power, the operating current is
increased (see Technical Data). When using the device for more than 4 hours, we suggest to use the DC
adaptor.
