INTRODUCTION
1-1. INTRODUCTION
This section provides equipment identification, a discussion of
equipment
features, and list equipment specifications.
1-2. GENERAL DESCRIPTION
The Series 3000 Cartridge machine is available in a wide range
of
monaural or stereophonic models to accomodate all sizes of cartridges
(see Figure 1-1). The Series 3000 is the first Broadcast Electronics Series
to incorporate
an automatic release deck. The units can be rack or desk
top
mounted. A large air damped solenoid and a rugged machined surface
ensures
trouble-free operation in continuous use.
Total
power consumption is low. An efficient hysteresis syn-
chronous drive motor
and a power conserving solenoid circuit keep total
power consumption below 45 watts. There is no excessive heat build up to
damage tape while still offering direct tape drive and optional fast
forward features.
Quality construction is standard with the Series 3000. All
components are readily available types chosen for proven dependability.
Modern integrated circuits, gold plated card edge contacts, and internally
shielded audio sections are among many features. Adjustments are accessible
and modular contruction is employed throughout.
Balanced transformer outputs are provided
on all models. Full
remote control
is provided at a rear panel receptacle. Mating connectors
are supplied
for all interconnections. Field effect transistor output
switching
is built into each machine to permit easy equipment paralleling.
The Series 3000 incorporates the Phase Lok IV head bracket which,
allows independent azimuth adjustment to assure extremely close control of
stereophonic phasing while permitting easy adjustment.
