The BLOCK and CYMBAL voices are programmed into the pedal
keyboard when their rocker tabs are “on”. The remaining four
voices are programmed into the lower manual keys when their
rocker tabs are “on”.
The RHYTHM VOLUME control, mounted to the right of the rocker
tabs, regulates the loudness of the rhythm voices relative to the
other organ voices. The organ’s expression pedal also affects the
rhythm voices except brush and cymbal.
The BRUSH and CYMBAL voices sound without reverberation,
The remaining voices are reverberated whenever a REVERB tab
on the organ’s control panel is depressed.
1–17 EXTERNAL EQUIPMENT
The L–100 Series organs may be equipped with extension
speakers, external inputs and earphones.
1–18 EXTENSION SPEAKERS
A Hammond Model PR-40 Tone Cabinet may be used as an
extension speaker, A Tone Cabinet Control Kit, P/N AO–22625–2
is required for proper interconnections. Installation instructions are
furnished with the kit.
1–19 EXTERNAL SOUND SOURCE
A record player or microphone equipped with a suitable
preamplifier, or a radio, can be played through the organ’s speaker.
The device used should have an output level of about ½ volt rms
maximum, and should have its own volume control, since the
organ volume controls will not affect the signal. The organ may be
played at the same time.
To connect an external sound source, a Switchcraft Type 330 F1
“ Y” connector is required. Remove the connector cable from the
WH (White) RCA terminal on the power amplifier.
Insert the “Y” connector into the terminal, and insert cable
previously removed into one arm of the “Y”. Connect the external
sound source to the other arm.
1–20 EARPHONES
In order to use earphones, the output jack and network shown
in
Figure 1–13 are required. When earphones are in use, organ
speakers are silenced.
