Level Att(Enuator); Input Selector Switch; Eq (Room Compensation) - Klein + Hummel O 300 D Installation And Operation Manual

1.7.2.2 Source 2x AES/EBU
1.7.2.3 Source 1x S/P-DIF or 1x AES 3id,
connection using two T - connectors
1.7.2.4 Source 2x S/P-DIF or 2x AES 3id

1.7.3 Level ATT(ENUATOR)

This rotary level control allows for continuous
damping of the input signal in a range from 0
to -24 dB in both analog and digital modes.

1.7.4 INPUT SELECTOR Switch

Use a screwdriver to change the position of
this recessed switch in order to select ana-
log or digital mode of operation. Since one
digital input carries both stereo channels, the
Input Selector has three additional positions
for establishing how the monitors are
assigned to the channels. This works as
follows:
Page 6
Position A = Analog mode (XLR input)
Position R = Digital mode right channel
Position L = Digital mode left channel
Position M = Digital mode mono (summed
Simultaneous operation from one analog and
one digital source is not possible. At any given
time you may connect only one type of source
to the pair.

1.7.5 EQ (Room compensation)

Three 4-way recessed rotary switches
(adjustable with a screwdriver) are available
for frequency compensation due to room
acoustics and speaker placement.
1.7.5.1 BASS Switch
For equalizing anomalies in the lower
frequencies due to proximity to room
boundaries:
Position 0 = free space
Position -3 = 1 boundary (wall)
Position -6 = 2 boundaries (corner)
Position -9 = 3 boundaries (corner + ceiling)
1.7.5.2 MID Switch
For equalizing anomalies in the midrange due
to reflections arising from placement on the
console's meter bridge:
Position 0 = free space
Position -2 = mid reduction of -2 dB
Position -4 = mid reduction of -4 dB
Position -6 = mid reduction of -6 dB

1.7.5.3 HIGH Switch
Compensates for high-frequency anomalies
3
due to excessive reflection or absorption in
the room:
Position 1 = treble boost of +1 dB
Position 0 = linear
Position -1 = treble reduction of -1 dB
Position -2 = treble reduction of -2 dB
Note: Since it is not feasible to list all possible
combinations of speaker placement and room
acoustics, we strongly recommend checking
the switch settings acoustically or by
measurement.
