Connecting the power supply of the amplifier:
Connect the amplifier to an earthed safety socket with the cable supplied with the Drum In Ear Amp 2.
Connecting the input signals channel 1 to 4:
There are four inputs for the input signals. All inputs are balanced XLR / jack hybrid panel mount
connectors with a nominal input sensitivity of -10 dBu. So you can connect XLR plugs or balanced and
unbalanced jack connectors.
Reasonably, the monitor signal (monitor outputs of a mixing console) or the left/right sum signal are
connected to channel 1 and 2. In stereo mode, channel 1 is output left and channel 2 is output at the right.
If you only want to feed in a mono signal and would like to hear the signal on both earphone sides, press
key Mono for channel 1-2 at the front side of the amplifier.
At the inputs for channel 3 and 4, additional signals (such as CD players, sequencers, click signals, etc.)
are connected. If you only want to feed in a mono signal and would like to hear the signal on both
earphone sides, press key Mono for channel3-4 at the front side of the amplifier.
If you would like to hear the click signal at the right side only, plug it into channel 4. If you would like to hear
the click signal at the right side only, plug it into channel 3. You can also connect different signals to
channels 3 and 4 (e. g. sequencer and click). If you would like to hear these two signals at both earphone
sides, press key Mono for channel 3-4 at the front side of the amplifier. With the balance control of channel
3-4 the volume ratio of both signals can be adjusted. This is referred to as Mono-Mix Mode.
OPERATION OF THE DRUM IN EAR AMP 2:
Adjustment of the optimum working level:
When all required connections are made and the Drum In Ear Amp 2 is switched on, make sure that the
input signals have contact with the Drum In Ear Amp 2. Turn channel 1-2 volume control until the green
and yellow signal LEDs light. The red clip LED may only flash with short signal peaks, but should not light
steadily. Then you have the optimum working level. When you have also connected input signals to
channel 3-4, proceed as explained above, but use channel 3-4 volume control. When the yellow signal
LED does not light when the volume control is at the right stop (maximum), increase the level of the
connected input signal at the source device.
If the red clip LEDs light, decrease the level at the input controls of channel 1-2 or channel 3-4, as
otherwise the limiters respond, and the dynamic range is restricted.
Adjustment of the Earphone/Headphone Volume:
Connect your earphones to the phones output jack at the front. Any headphone system with an impedance
greater or equal 12 ohms can be connected at this jack. If your headphone system has a 1/8” stereo
connector, use the adapter supplied with the Drum In Ear Amp 2. Now adjust the volume which is
convenient for you with the volume control (Phones Out).
IMPORTANT: Use stereo headphone systems with 3-pole jack connectors.
Adjustment of the Intensity of the Bass Shaker:
Sit on the drummer seat and set the volume control of the bass shaker to an intensity which is convenient
for you compared to the earphone volume. The characteristics of the bass signal can be adjusted by
means of the cut-off frequency control of the bass shaker output. The more you turn the control in
clockwise direction, the more higher frequencies are output to the bass shaker (up to max. 200 Hz). The
adjustment you select can completely depend on your personal taste. Fischer Amps, however, recommend
a cut-off frequency of approx. 80 Hz.
