>> Front Panel
8 HI
The “HI” control is centred at 8 kHz and offers a cut or
boost of 15 dB. Turn it up for a biting, crystal clear rock
or funk bass. Turn it counter clockwise to reduce hiss or
generally dampen the sound for a muted reggae feel.
9 MASTER
This is the overall volume control of the PUMA and works
on internal power amp. It determines the level at the
“SPEAKER OUTPUTS” (#19) as well as the “LINE OUT”
jack on the back panel (#17). Furthermore you can control
the level of the audio source connected to the Aux In jack
to blend it with your bass signal.
10 MUTE
The “MUTE” switch should be depressed when you po-
wer up or down your PUMA – the LED above the switch
illuminates when the function is engaged. In this mode
no audio signal will be processed and heard at any out-
put except the “TUNER” jack (#19). That way you don’t
have to turn down the volume for silent tuning or when
changing instruments, thus you do without the nasty
cling which you usually hear when you unplug the jack.
The “MUTE” switch also interrupts the signal path at
the balanced “DI OUT” (#12), no matter which position
the switch “DI POST” (#11) is in (that way your silent
tuning or changing instruments won’t be heard in the PA,
either). During breaks the amp should be set to “MUTE”
rather than switched off completely. That way the in-
ternal fan (only Puma 900) stays on and cools down the
power amp circuitry if necessary. Disengage the “MUTE”
function and start to rumble – now there is signal at all
outputs again.
11 POST
With this switch the balanced “DI OUT” (#12) can be
selected to be a “PRE” or “POST” preamp signal. In the
“PRE” position (switch is not depressed) the “DI OUT”
signal is tapped directly after the input stage including
the “GAIN” control (#3).
In the “POST” position (switch depressed) the “DI OUT”
signal is taken after it has been processed by the com-
plete preamp, i.e. including the “GAIN” control (#3), the
tone control section (#5 through #8), and the “EFFECTS
LOOP” (#18). It is not affected by the “MASTER” control
(#9). As a reference the LED above the “POST” switch
illuminates when the “DI OUT” is set to “POST”.
12 DI
PUMA supplies a balanced line output signal for con-
necting to a house mixing board, recording console or
external amplifier(s) with balanced inputs. Connect a
shielded 3-core microphone cable with XLR plugs to this
male XLR output.
The need for an additional active DI box, which can be
pretty expensive, is obsolete. Due to the advanced cir-
cuit design using only the best components available the
high sound quality of the “DI OUT” makes it the amp of
choice in any recording studio (you can use the PUMA’s
pre amp on its own without driving any speakers). The DI
signal can be tapped either before or after the preamp,
as determined by the switch “POST” (#11). There is no
need to be afraid of nasty ground loops as the DI output
is soft-grounded.
13a ON
Provided the included power cord is plugged into the pow-
er socket on the back panel (#14) and into an appropriate
wall socket, the blue line on the front panel will illuminate
when the power switch (#13) is turned on, no matter what
positions other switches are in.
