HPF High Pass Filter selector. Use this to reduce undesirable low frequency
background noise. The 80Hz setting is appropriate for many musical and voice
applications. Note that use of the HPF will most likely not eliminate the need for a pop
screen for close-mic’d vocal use.
The INSTRUMENT input (DI) is used for connection of electric instrument pickup or
synthesizers. The DI we’ve designed for the
P-SOLO matches (or exceeds) the sonic
performance of acclaimed, dedicated DI products. It provides excellent articulation and
control for electric/acoustic bass, detail and smoothness for stringed instruments and
keyboards. A microphone plugged into MIC IN will be automatically de-selected when
an instrument is connected to the INSTRUMENT input. Settings for GAIN and HPF
apply to the DI input in the same manner as they apply to mic input. The gain range for
the direct inputs is from -4 dB to +44 dB at normal gain and -14 dB in the INP ATTEN
mode.
NOTE: The INSTRUMENT input is for unbalanced sources only. DO NOT use a TRS
(balanced) plug for this input, as the DI will not function correctly.
Level Indicators. Use these to match signal level between the P-SOLO and devices to
which it is connected - and to avoid overloading the preamp.
 SIG indicates that a signal is present on the channel. It illuminates when the signal
level exceeds -24dBu.
 +4 illuminates when the signal reaches normal operating level of +4 dBu.
 OL illuminates when the signal level exceeds +26 dBu, which is 5 dB below the
overload point for the P-SOLO *.
 .Note that the overload level of the P-SOLO is +31dBu at the output*. This level
exceeds the input capability of some devices (check manufacturer’s specifications).
In such cases it is appropriate to use the intermediate level indicators (+4, +12) to
set the maximum output level of the
P-SOLO to match the maximum input capability
of the connected device. In other words, it is possible to cause overload distortion in
the connected device even though the
P-SOLO level indicator does not show a red
light. * Maximum output level in the INP ATTEN mode is +27dBu.
