Click Out - The Click Out is a TTL-level output
pul~e.
When
enabled from the Front Panel,. a positive pulse appears at this
output.
Its repetition rate is the 'selected sequencer tempo.
Driving source is
a low power TTL gate through a
51
ohm
resistor. This
I/O port takes a
r1/4
inch phone jack.
Sync
In
- The Sync
In
is a TTL-compatible input used
to
drive
the
K250 from another instrument. The other instrument is to
provide a square wave at X12 to X96 the tempo. The input
impedance is greater than
10k ohms. The trigger level is 2
volts and this
I/O port takes a 1/4 inch phone jack.
Sync Out - The Sync
Out
is a TTL-level square wave output
used to drive another instrument
in
synchrony with the K250.
The repetition rate is normally X12
to
X96 the tempo. The
driving source is a low power TTL gate through a
51
ohm
resistor. This
I/O port takes a 1/4
in
phone jack.
LO - These are 2.6, absolute maximum, VPP audio outputs, with
a
600 ohm driving source impedance. Typical output levels are
an
order of magnitude lower than maximums. These require
114
inch phone jacks and are suitable for line level inputs.
ill
- These are 26, absolute maximim, VPP audio outputs, with
a
600 ohm driving source impedance. Typical output levels are
an
order of magnitude lower than maximums. These require
1/4 inch phone jacks and are suitable for directly driving
power
amplifiers and other high level inputs.
Balanced
- These are 26, absolute maximum, VPP audio
outputs. They have XLF connectors, floating outputs and a
600
ohm driving source impedance. Typical output levels are
an
order of magnitude lower than maximums.
External Pedals 1 and 2 - The
114
inch phone jacks accept
external pedals.
