OUTPUT EQUIPMENT
The output of any model Hammond Organ can be connected to earphones, disc and tape
recorder, or broadcast equipment. If necessary, it may be connected to play through
a public address system, although this is generally not desirable. Since so many
types of external equipment are in use, the following general suggestions may have
to be modified somewhat to fit individual cases.
Figures 7 to 10 show various types of output connections.
PLAYING THROUGH EARPHONES
It is important to use only high quality earphones. We recommend the dynamic or
moving coil type, which are quite expensive but give really excellent results. If
the organ is not equipped with reverberation control, crystal earphones will be very
satisfactory if connected as shown in figure 10. On an organ equipped with
reverberation control, the power amplifier connection is best, and good quality
magnetic earphones will give quite satisfactory results. Crystal earphones can be
used in this circuit, but are likely to be less satisfactory than the best quality
magnetic units.
For Home. Church or Concert Model Organ (Models A. AV, B, BA, BC,
BV, BCV, B-2. B-3, C, CV, C-2, D, DV, E, G, GV, RT, RT-2), the preferred
connection is to the power amplifier in the tone cabinet, if the organ is equipped
with reverberation control, since this provides reverberated signal to the
earphones. Refer to figure 7, if tone cabinet is type HR-40 or JR-2O, or to figure 8
for other models. If crystal earphones are used, connect a .1 megohm resistor in
series to avoid excessive high frequencies.
