Bogen Classic Series User Manual

MICROPHONE PRECEDENCE: A buUt-in circuit pro
vides microphone precedence over the AUX 2 channel. For
this fi inction, a customer-supplied normally-open SPST
switch must be connected to the AUX 2 MUTE terminals.
When the contacts are closed, the microphone will have
precedence over the AUX 2 input.
AUXILIARY: The AUX inputs may be used for ai^ signal
source having a high-level output, including sudi Bogen
equipment as the TF-50A and TP-IOOA AM/FM "nmcrs,
CR-100 Cassette Player/Tuner, and TG-4C Multiple Tone
Generator.
TEL: Connect the telephone line to the TEL tenninals.
OUTPUT CONNECTIONS
SPEAKERS: The amplifier m^ be used with most conven
tional speaker systems. Coimect onespeakerlead tothe screw
terminal which cone^nds to die impedance of the speaker
system and the other lead to the COM terminal. If the line is
Welded, connect die shield to GND. For balanced ouqiut
lines, lemoye the link between the COM and GND ouqiut
tenninals. Class 2 wiring be used.
TAPE RECORDING: To tape record die amplifier pro
gram, connect a patch cord from the TAPE/BOOSTER out
put jade to the input of die tape recorder. The patdi cord
should be single-conductor, low-capaci^ shielded wire, un
der 3S feet in length, and terminated in a standard RCA phono
plug.
BOOSTX31 AMPLIFIER: To drive a booster anqilifier,
connect a patch cord fi ro m the TAPE/BOOSTER ou^t jack
to the input of the booster anqilifier. The patch cord should
be single-conductor, low-c^aci^ shielded wire, under 35
feet in length, and terminated in a standard RCA phono plug.
OPERATION
POWER: The front panel ON/OFF switch applies power to
the amplifier and is illuminated when power is ON.
MIC 1, MIC 2: For two microphone inputs, the MIC 2/AUX
1 selector switch should be in the MIC 2 mode. The MIC
controls are used to adjust the volume of the microphone
irqmts. Rotate the controls clockwise to increase volume and
counterclockwise to decrease it. Turn the controls to the
minimum position if the inputs are not used.
AUX I, AUX 2: For two auxiliary inputs, the MIC 2/AUX 1
selector switdi should be in the AUX 1 mode. The AUX
controls are used to adjust the volume of the auxiliaty irq>uts.
Rotate fi re controls clodcwise to increase volume and coun
terclockwise to decrease it. Turn the controls to the minimum
position if the irq)uts are not used.
TEL: The 1EL VOLUME control on the rear panel adjusts
the telephone paging level, h does riot affect the microphone
level. Rotate the control counterclockwise to decrease the
level. Rotate the control clockwise to increase the level.
VOX SENS: The VOX SENSitivi^ control should be set so
that only the desired signal is above &e threshold level, while
noise and tmwanted signal is below It. When an input signal
(such as voice) is detected, the music channel will be muted.
To adjust the sensitivi^ of this circuit:
1. Rotate the control fully dockwise. While making a page
aimouncemait and talking at a low level, the sound should
not be choppy nor missing parts of words. If it is choppy,
or if intelli^bility is poor, ro tate the control counterclock
wise to the point where die sound is clear and crisp (but
not to the fna«iTnum counterclockvvise position).
2. If the background music shuts down when no page is in
progress, ro tate die control clockwise until the music is
restored.
t-:
MICROPHONE PRECEDENCE: Muting of AUX 2 re
quires a customer-supplied external switch, whidi must be
coimected to the AUX 2 MUTE tenninals. When the contacts
are closed, the microphones will have precedence over the
AUX 2 input.
BASS, TREBLE: The BASS and TREBLE controls are used
to adjust the tonal balance of the amplifier output. The center
position of these controls provides flat frequency response.
Counterclockwise rotation of these controls reduces the bass
or treble response, while clockwise rotadon increases re
sponse.
